Marijuana: Medical Use Overview

The use of marijuana for medical purposes remains highly controversial and is fraught with a lack of good quality evidence regarding the specifics of clinical effectiveness and the details of treatment including dosing frequency, amount and duration. The following information is provided as an introduction to what is believed to be true about medical uses of marijuana. There will surely be more information to come.



Prescription Cannabinoids

The term “prescription cannabinoid” refers to products containing one or more marijuana plant-derived or synthetically manufactured cannabinoids that are available by prescription only. Currently in the U.S. only three prescription cannabinoids are FDA-approved and legal to be prescribed in all states. Other, non-FDA approved cannabis based pharmaceutical products are available depending on the state.


Medical Marijuana:

This term is in popular use but it is imprecise.  It generally refers broadly to dried cannabis dispensed or otherwise obtained and used either for supervised medical purposes or for self-medication. In a more accurate context, the term “cannabis” or “dried cannabis” is preferred when describing the plant form.


Cannabis/Dried Cannabis:

The terms “cannabis” or “dried cannabis” refer to the marijuana in its plant form.


Pharmaceutical Cannabis Products:

The term “pharmaceutical cannabis” refers to products that are derived from the marijuana plant and manufactured under controlled commercial conditions. Which of these products are available without a prescription varies state by state and the quality of manufacturing may also vary significantly from one product to another, with little to no regulatory oversight over the manufacturing process.


In Louisiana, the only pharmaceutical cannabinoid currently legal and available without a prescription is cannabidiol, and only if it is 100% pure and manufactured from cannabis stems or seeds, not leaves or flowers. While technically this is true, it appears that cannabis-based products derived from either whole plant or aerial (above ground) parts of the plant are available OTC locally as long as their THC content is <0.3%. Louisiana has now legalized prescription cannabinoids including THC but, at least initially, they are to be provided in the forms of capsules or tablets and liquid tinctures only, nothing that is intended to be smoked or “vaped.” Prescription cannabis-based products are expected to become available in LA in late 2018 or early 2019.

MarijuanaPotential for Therapeutic Benefit

There is currently a great deal of attention, both nationally and internationlly, on the potential medical benefits of marijuana (cannabis). The reasons for this are multiple, not the least of which is financial. That being said, however, there is a massive interest in therapeutic cannabis. One major reason for this is that in parallel with medical science’s interest in cannabis, is the associated interest in how cannabis offers medical benefits.


Patients have many reasons to advocate for use of cannabinoids in general and herbal cannabis in particular. These include the poor performance of currently available pain therapies, skepticism about the pharmaceutical industry, anecdotal and media reports reporting the effectiveness of herbal cannabis, familiarity with the marijuana because of past recreational use and knowledge that marijuana has been used for millennia for medical purposes.


The evaluation of cannabis has led to a grand new arena of knowledge surrounding a new neuroendocrine system in humans and animals not previously known and even now very poorly understood, But it is huge. The “endocannabinoid system,” explained further below, is present throughout the brain, central nervous system and all other organ systems. It represents an extremely important new field of study for understanding how our bodies work and it offers an excciting new world of therapeutic possibilities. It is a new frontier in medical science.


Our current understanding of medical uses of cannabis are, unfortunately, based on only a rudimentary beginning of research with little definitive knowledge established. The nature of the research currently available to the medical community to direct clinicians toward safe and effective applications of cannabis therapeutically is very limited and based mostly on observational studies which provide very limited useful information to guide cannabis prescribing.


Cannabis – Research Studies

Observational studies are those in which data is reviewed by an investigator who observes individuals without manipulation or intervention and draws inferences from a population where no independent variables are under the control of the researcher. Observational studies can determine if there are associations between an activity and an outcome but cannot identify or confirm cause and effect. This is in contrast to randomised controlled trials (RCTs) where investigators do intervene and look at the effects of the intervention on an outcome. Randomised controlled trials are useful in determining causal relationships between treatment and outcome such as whether a medication actually works for a particular conditi0n. There are few randomised controlled trials (RCTs) to provide specifics for establishing treatment protocols.


There are many preclinical studies (animal and labatory-based research) that have shown that modulating the activity of the ECS with cannabinoids is effective for mood and anxiety disorders, movement disorders, neuropathic (nerve) pain, epilepsy, multiple sclerosis, spinal cord injury, cancer, atherosclerosis, myocardial infarction, stroke, hypertension, glaucoma, obesity/metabolic syndrome, insomnia, drug addiction, Alzheimer’s disease, and osteoporosis.  Unfortunately, there remains a lack of good quality human-based research to confirm the specifics of what the preclinical studies suggest. Most human research has focused on spasticity, nausea and vomiting, anorexia, and chronic pain. Some conditions, such as migraine headaches, fibromyalgia, and Irritable Bowel Syndrome (IBS) have underlying physiological patterns that suggest an underlying endocannabinoid deficiency, suggesting they may be effectively treated with cannabinoid medicines.


The Endocannabinoid System (ECS): Endocannabinoids and Phytocannabinoids

There are a number of physiologically active constituents of the cannabis (marijuana) plant, some of which have shown therapeutic benefits in a broad range of conditions. One group of compounds found to be uniquely abundant in cannabis is the “cannabinoids.”  Originally thought to be unique to cannabis, naturally occuring cannabinoids (endocannabinoids) were subsequently discovered in humans and animals (all vertebrates). An entire endocannabinoid system consisting of multiple types of endocannabinoids and cannabinoid receptors is distributed throughout the body.


This endocannabinoid system of endocannabinoids and receptors is similar to the presence of opioid receptors in the body that are related to naturally occuring opioids (endorphins) in the body. The ECS regulates many physiologic functions ranging from the immune system to the nervous system and impacts sleep, appetite, mood, pain and other functions. For this reason, marijuana has attracted a great deal of attention from a pharmacotherapy perspective for its potential to affect many physiologic functions with possible benefit. 


The clinical benefits from marijuana are derived from the many chemical agents found in the plant, including more than 100 pharmacologically active constituents, including cannabinoids and terpenes. The two best understood and most common of the cannabinoids are THC (tetrahydrocannabinol) and CBD (cannabidiol). There is very limited scientific information on the pharmacology and toxicology of the other constituents found in cannabis. It is believed that the clinical effects of marijuana come from not just THC or CBD, but are determined by both the concentrations and ratios of these two constituents as well as the influences from the many other cannabinoids and terpenes found in the plant.


THC (tetrahydrocannabinol)

THC is responsible for many of the clinical effects of marijuana, including the analgesic, anti-spasmodic, anti-tremor, anti-inflammatory, appetite stimulant and anti-emetic properties.  THC and its active metabolite, 11-Hydroxy-THC. produce the “high” or euphoria associated with use of marijuana.


CBD (cannabidiol)

CBD does not produce the mind-altering “high” effects like euphoria but it does reduce anxiety and enhance sleep. CBD is a versatile anti-inflammatory analgesic, operating through numerous distinct mechanisms. It has anti-convulsant, anti-psychotic, antioxidant, neuroprotective and immunomodulatory effects. CBD is also thought to reduce nausea, particularly related to chemotherapy. In combination with THC, CBD modulates some of the side effects of THC, including reducing THC-induced anxiety.






Marijuana – Potential for Harm

 While there is great hope for the therapeutic potential of cannabis, it is not for everyone and certain groups have been identifid who should likely avoid use of cannabis. The following groups are believed to be at increased risk of harm from use of cannabis:


  1. Children, adolescents, and young adults (<25 y/0)

  2. Women who are pregnant or breastfeeding

  3. Those with a personal or family history of psychotic disorders such as schizophrenia

  4. Those with a history of chronic lung disease, cardiovascular disease and/or kidney disease


    Children, Adolescents, and Young Adults (<25 y/o)

  1. While animal studies suggest use of cannabinoids alters brain development in adolescence, human studies are more inconclusive. Generally speaking, human studies have evaluated two broad categories of evidence. First, non-invasive brain imaging studies measure structural and functional changes within the brain. Second, studies have evaluated changes in neurocognitive functioning in cannabis users.


    Human brain imaging studies that have identified structural differences in young cannabis users compared with non-users. The majority of the evidence finds changes in the medial temporal regions (learning and memory, emotional processing) and frontal regions (decision-making, executive functioning, response inhibition, emotion regulation). However, not all studies have supported these conclusions.


    Studies evaluating neurocognitive functioning in adolescents also remain divided in their conclusions regarding the effects of cannabis on brain development. There is growing evidence that adolescent cannabis use is particularly associated with impaired attentional processing, executive functioning, and memory but the actual degree to which adolescent cannabis use is directly related to these declines is uncertain.


    Longitudinal research spanning nearly 3 decades revealed mixed results. One important study measured intelligence in early adolescence (age 13 – prior to the participants’ use of cannabis) and monitored for changes in intelligence through age 38. More frequent cannabis use was associated with declines in IQ by age 38 as well as more frequent findings of cannabis dependence. In contrast, in a more recent longitudinal study of IQ, this relationship did not hold. In particular, this study evaluating identical twin pairs showed that cannabis use does not directly cause declines in IQ.


    It should be noted that the studies described here are primarily based on the use of recreational cannabis products which have relatively high levels of THC. Medical cannabis products, on the other hand, have varying levels and ratios of THC to CBD and their use may not result in the same findings. More research is needed to clarify the risks and dangers of cannabis use in adolescents and young adults. In the meantime, great caution weighing the potential benefits against the uncertain risks should be engaged prior to treatment with cannabis products in these age groups.


Pregnant and Breastfeeding

Animal studies demonstrate that tetrahydrocannabinol (THC) crosses the placenta and results in fetal THC plasma levels approximately 10% of maternal levels after acute exposure and repeat exposure can result in much higher fetal concentrations. Both animal and human studies suggest that prenatal or perinatal cannabis use can result in long-term neurological impairments. The American College of Obstetricians and Gynecologists Committee on Obstetric Practice discourages the use of medical cannabis during preconception, pregnancy and breastfeeding due to concern for potential harm including impaired neurologic development.


Evidence also suggests cannabis use during pregnancy may be linked to preterm delivery, low birth weight or growth issues, birth defects, newborn behavioral issues as well as long-term impaired cognitive and behavioral functioning. There is also limited evidence that cannabis use is associated with greater risk of stillbirth, birth defects including anencephaly (severely impaired brain development) and heart defects.


Much of the concern around cannabis use during pregnancy is focused on long term cognitive functioning and behavioral impairment. There is moderate evidence from two large longitudinal studies that suggest prenatal cannabis use is linked to lower IQ scores and decreased cognitive functioning later in life. There is also limited evidence that cannabis use is associated with behavioral problems such as attention problems, aggression, hyperactivity, impulsivity, depression and delinquent behaviors.


Evidence regarding cannabis use while breastfeeding is extremely limited. THC can be detected in the breast milk of women using cannabis but research is mixed on whether cannabis use during breastfeeding is associated with poorer motor development in infants.


Cannabis Use in Persons with Psychotic Disorders

Use of cannabis by patients with established psychotic disorders is likely associated with increased relapse  and decreased adherence to treatment but the association between cannabis use and psychotic symptoms or other psychopathology remain unclear.The association between cannabis use and psychotic symptoms appears to be bi-directional: changes in cannabis use predicts changes in psychotic symptoms and vice versa. 


Studies evaluating cannabis use patients with new onset psychosis show that reduced use of cannabis is associated with better psychological function and decreased anxiety. Additionally, patients with new-onset psychotic disease who are using cannabis at baseline but subsequently discontinue use have better psychological functioning and fewer negative symptoms than patients who continue cannabis use.



Cannabis Use and Onset of Psychotic Disorder

A review of many studies concludes that cannabis is neither a necessary nor a sufficient cause of psychosis but that it could be a contributing factor that interacts with genetic and environmental factors in vulnerable individuals. The causal nature of the association is unclear and includes the “reverse causality“ hypothesis – that is, the discomfort caused by early symptoms of psychotic disease leads some people to use marijuana for relief.


Recent evidence suggests there may be a causal role for cannabis use, especially for persons already at increased risk for developing a psychotic disorder due genetics, history of child mistreatment, or other reasons. It has been reported that age of onset of psychosis for cannabis users is 2.7 years younger than for non-users. Onset of schizophrenia usually occurs in late adolescence or early adulthood, a time at which a delay of a few years could allow many patients to achieve important developmental milestones of late adolescence and early adulthood that could reduce long-term disability resulting from the schizophrenia. However studies remain conflicting as to whether cannabis or THC contributes as a cause of schizophrenia. THC is clearly recognized to be the cause of psychotic effects and use of higher TCH products has been shown to be more strongly associated with development of psychotic disease than use of lower THC cannabis. But there is also growing evidence that CBD has anti-psychotic benefits.


The research on associations between cannabis use and psychotic disease is based nearly exclusively on use of recreational cannabis products, which have relatively high levels of THC. Products accessed through the a medical cannabis program, on the other hand, have varying ratios of THC to CBD so existing research may not apply to patients using medical cannabis products whose CBD content approaches or surpasses its THC content.


Chronic lung, cardiovascular, and/or kidney disease

Due to a lack of evidence regarding the safety of cannabis use in patients with these chronic medical conditions, cannabis use in this population should be avoided or initiated with caution.



Clinical Evidence for Effectiveness

Research on Medical Marijuana

Definitive research regarding the medical uses of marijuana and its constitutents remains limited and in only early stages. Observational studies are those in which data is reviewed by an investigator who observes individuals without manipulation or intervention and draws inferences from a population where no independent variables are under the control of the researcher. Observational studies can determine if there are associations between an activity and an outcome but cannot identify or confirm cause and effect. This is in contrast to randomised controlled trials (RCTs) where investigators do intervene and look at the effects of the intervention on an outcome. Randomised controlled trials are useful in determining causal relationships between treatment and outcome such as whether a medication actually works for a particular conditi0n..

The current state of medical marijuana research is based mostly in observational studies with very few RCTs to guide management of most medical conditions with specific cannabis-based treatments.

Based on the 2017 report from the National Academies of Sciences, Engineering, and Medicine there is conclusive or substantial evidence that cannabis or cannabinoids are effective for the treatment of:


  1. Chronic pain in adults
  2. Chemotherapy-induced nausea and vomiting
  3. Multiple sclerosis spasticity symptoms


The report also found moderate evidence that cannabis or cannabinoids are effective for:

  1. Improving short-term sleep outcomes in individuals with sleep disturbance associated with obstructive sleep apnea syndrome (See: Sleep Apnea)
  2. Fibromyalgia
  3. Multiple sclerosis


Additionally, there is increasing but limited research showing that cannabinoids are safe and effective in the treatment of:

  1. Seizure disorders
  2. Increasing appetite and decreasing weight loss associated with HIV/AIDS
  3. Tourette syndrome
  4. Several geriatric conditions
  5. Anxiety, particularly in individuals with PTSD and social anxiety disorder
  6. Depression, associated with chronic pain
  7. Neurocognition in some cases of dementia


Clinical Evidence For Harm – Highlights

Based on the 2017 report from the National Academies of Sciences, Engineering, and Medicine, the following conclusions have been drawn.


Cardiovascular Risk

  1. The evidence is unclear as to whether and how cannabis use is associated with heart attack, stroke, and diabetes.



  1. The evidence suggests that smoking cannabis does not increase the risk for certain cancers (i.e., lung, head, and neck) in adults.
  2. There is modest evidence that cannabis use is associated with one subtype of testicular cancer.
  3. There is minimal evidence that parental cannabis use during pregnancy is associated with greater cancer risk in offspring.



  1. There exists a paucity of data on the effects of cannabis or cannabinoid-based therapeutics on the human immune system.
  2. There is insufficient data to draw overarching conclusions concerning the effects of cannabis smoke or cannabinoids on immune competence.
  3. There is limited evidence to suggest that regular exposure to cannabis smoke may have anti-inflammatory activity.
  4. There is insufficient evidence to support or refute a statistical association between cannabis or cannabinoid use and adverse effects on immune status in individuals with HIV.


Prenatal, Perinatal, and Neonatal Exposure

  1. Smoking cannabis during pregnancy is linked to lower birth weight in the offspring.
  2. The relationship between smoking cannabis during pregnancy and other pregnancy and childhood outcomes is unclear.


Problem Cannabis Use

  1. Greater frequency of cannabis use increases the likelihood of developing problem cannabis use.
  2. Initiating cannabis use at a younger age increases the likelihood of developing problem cannabis use.


Cannabis Use and Abuse of Other Substances

  1. Cannabis use is likely to increase the risk for developing substance dependence (other than cannabis use disorder).


Injury and Death

  1. Cannabis use prior to driving increases the risk of being involved in a motor vehicle accident.
  2. In states where cannabis use is legal, there is increased risk of unintentional cannabis overdose injuries among children.
  3. It is unclear whether and how cannabis use is associated with all-cause mortality or with occupational injury.


Mental Health

  1. Cannabis use is likely to increase the risk of developing schizophrenia and other psychoses; the higher the use the greater the risk.
  2. In individuals with schizophrenia and other psychoses, a history of cannabis use may be linked to better performance on learning and memory tasks.
  3. Cannabis use does not appear to increase the likelihood of developing depression, anxiety, and posttraumatic stress disorder.
  4. For individuals diagnosed with bipolar disorders, near daily cannabis use may be linked to greater symptoms of bipolar disorder than non-users.
  5. Heavy cannabis users are more likely to report thoughts of suicide than non-users.
  6. Regular cannabis use is likely to increase the risk for developing social anxiety disorder.



  1. Recent cannabis use impairs the performance in cognitive domains of learning, memory, and attention. Recent use may be defined as cannabis use within 24 hours of evaluation.
  2. A limited number of studies suggest that there are impairments in cognitive domains of learning, memory, and attention in individuals who have stopped smoking cannabis.
  3. Cannabis use during adolescence is related to impairments in subsequent academic achievement and education, employment and income, and social relationships and social roles.


Respiratory Disease

  1. Smoking cannabis on a regular basis is associated with chronic cough and phlegm production.
  2. Quitting cannabis smoking is likely to reduce chronic cough and production of phlegm.
  3. It is unclear whether cannabis use is associated with COPD, asthma, or worsened lung function.



  1. While there can be adverse effects associated with the use of marijuana and cannabanoids, their use is considered safe. No acute fatal cases due to cannabinoid toxicity has been documented in humans. While the effective oral dosing range of plant-based cannabinoids in humans is 0.05 -25mg/kg/day,  no deaths occurred in monkeys treated acutely with oral dosing of THC 9,000mg/kg.
  2. Myocardial infarction (heart attack) may be triggered by inhaled THC in individuals who are unable to tolerate secondary side effects such as rapid heart rate or drop in blood pressure.



Inhaled cannabis, illegal in Louisiana, is contraindicated in:  

  1. Patients who are 25 years of age or younger
  2. Patients who have a current, past, or strong family history of psychosis
  3. Patients who have a current or past cannabis use disorder (marijuana addiction)
  4. Patients who have a current substance use disorder (chemical or behavioral)
  5. Patients who have cardiovascular or respiratory disease
  6. Patients who are pregnant or planning to become pregnant]
  7. Inhaled cannabis should be used with caution in patients who smoke tobaccco



Cannabis products should be used with caution in:

  1. Patients who are at increased risk of cardiovascular disease
  2. Patients who have anxiety or mood disorders
  3. Patients who are taking opioids or benzodiazepines


Harm Reduction:

  1. Do not operate dangerous equipment or perform potentially dangerous activities after use
  2. Do not use with alcohol, opioids, or sedating drugs, especially benzodiazepines (Valium, Xanax, Klonopin etc)
  3. Keep cannabis safely stored under lock and key


Cannabis users should be advised not to drive for at least:

  1. Three to four (3 to 4) hours after smoking
  2. Six (6) hours after oral ingestion
  3. Eight (8) hours if they experience a subjective “high”


THC serum concentrations of 2–5 μg/L have been shown to impair driving, and concentrations of 7–10 μg/L can produce impairment equivalent to a blood alcohol concentration of 0.05%. Sweden and Australia have zero tolerance for illegal drugs in drivers. If a 5-μg/L THC blood cutoff were adopted in Sweden, 90% of convicted impaired drivers would not have been prosecuted; 61% of prosecuted drivers would have been missed with a >1 μg/L cutoff.


Two states, Nevada and Ohio, have set blood per se limits of ≥2 μg/L for THC or ≥5 μg/L for THCCOOH and Colorado has set(?) a per se limit of 5.0 μg/L THC in blood.. The highest per se limits in Europe are 3 μg/L for THC in Portugal and 50 μg/L for THCCOOH in Poland. While existing laws focus on THC and THCCOOH per se concentrations, appropriate cutoffs might also be selected for 11-OH-THC due its shorter detection window. THC- glucuronide, cannabinol, and cannabidiol concentrations in blood may also indicate recent cannabis smoking.


Of note, cannabinoids can be detected in blood of chronic daily cannabis smokers for a month after sustained abstinence. This is consistent with the time course of persisting neurocognitive impairment reported in recent studies. There is a strong public safety need to reduce cannabis-impaired driving  and reduce cannabis-related motor vehicle injuries and deaths.


Dosing – Prescription Cannabanoids

See: Marijuana (Cannabis) – Prescription Cannabanoids


It is beyond the scope of this web site to provide any meaningful dosing recommendations for CBD or THC. With as many as 850 brands of marijuana-derived CBD products and 150 hemp-derived products on the market and an even greater number of various extracts of THC and marijuana plants cultivated to produce maximum THC concentration, universal dosing recommendations are nearly impossible.


In Germany currently there are 14 types of cannabis flowers that can be prescribed, with THC concentrations varying between 1% and 22% and CBD concentrations varying between 0.05% and 9%. Dosing information for specific indications is not available but the German Narcotic Drugs Act sets the maximum amount that can be prescribed within a 30-day period at 100 g cannabis in form of flowers, regardless of THC content. While  THC-containing capsules and oil are not permitted under the German Narcotic Drugs Act, they can be prescribed for individual therapeutic trials as compounded medications in the form of drops, capsules or inhalation solution. The recommended daily doses range between 5 and 30 mg.



Dosing – Dried Cannabis

See: Marijuana – Inhaled (Smoked and Vaporized)

  1. The determination of dosing is one of the major stumbling blocks in the study of medical marijuana. This is because marijuana, a plant, varies widely in the amount and ratios of the pharmacologically active constituents present depending on a multitude of variables. Depending on the plant there may be over 100 pharmacologically active constituents all of which vary depending on the genetics of the plant, the conditions in which the plant was grown, how and when it was harvested and other variables. As such there is a huge variability in the potency and expected effects between different plants.
  2. As noted above, the major pharmacologically active cannabinoids in marijuana are THC and cannabidiol (CBD). The average contents of THC and CBD in dried plant preparations of marijuana confiscated from 1993 to 2008 in the United States were 4.5 and 0.4, respectively, although these contents vary widely. In the last decade these percentages have increased in different strains to more than 3-5 times as potent.


Inhaled Cannabis (Smoked and Vaped)

At the current time, Louisiana legislation for medical marijuana does not permit products to be inhaled, either by smoking or vaping. It is not yet known what products and their potencies will be provided under current Louisiana legislstion.

See: Marijuana – Inhaled (Smoked and Vaporized)


Based on Canadian guidelines published in 2014, smoked cannabis might be indicated for patients with severe neuropathic pain conditions who have not responded to adequate trials of pharmaceutical cannabinoids and standard analgesics. Smoked cannabis is contraindicated in patients who: (1) are 25 years of age or younger; (2) have a current, past, or strong family history of psychosis; (3) have a current or past cannabis use disorder (marijuana addiction); (4) have a current substance use disorder (addiction to other drugs); (5) have cardiovascular or respiratory disease; or (6) are pregnant or planning to become pregnant. It should be used with caution in patients who smoke tobacco, who are at increased risk of cardiovascular disease, who have anxiety or mood disorders, or who are taking high doses of opioids or benzodiazepines.


Based on these Canadian guidelines, when smoking is advised (which it is generally not), initial dosing recommendations for smoked marijuana are usually for small amounts of lower-potency marijuana. For example, the starting recommended dosing is 1 inhalation of a 9% maximum THC “joint” once per day. This can be increased to a maximum recommended dose of 1 inhalation 4 times a day, resulting in approximately half a “joint” per day (or 400 mg). People should not operate dangerous equipment or perform potentially dangerous activities after use. This includes no driving for 3 to 4 hours after inhaled medical marijuana, 6 hours after oral ingestion, and for at least 8 hours if they experience a subjective “high.”


Higher doses are sometimes used. It should be noted that if patients use a 5 gram dose of 15% THC, this represents approximately a 20 times higher dose than the recommended 400 mg of 9% THC. Higher doses, especially at this level are associated with significantly higher risk of adverse side effects (see below). In marijuana resin (commonly referred to as hash or hashish), the mean contents of THC, CBD, and CBN are 14.1, 2.5, and 1.9%, respectively. Other commercial products including oils and edibles may contain even higher potencies.


Adverse Side Effects

Overall, the adverse side effects of medical cannabis are within the range tolerated for other common medications. Multiple studies have demonstrated that there is no higher incidence of serious adverse events in cannabis subjects following medical cannabis use compared with control subjects, although non-serious adverse events were significantly higher in cannabinoid groups. Dizziness is the most common non-serious adverse reported. Other common adverse effects include:


  1. Euphoria, altered consciousness
  2. Acute panic or paranoid reaction
  3. Altered motivation
  4. Impaired attention, memory, and psychomotor performance
  5. Tachycardia, orthostatic hypotension (drop in blood pressure associated with sitting to standing)
  6. Dry mouth
  7. Increased appetite
  8. Cognitive impairment, including the ability to learn and remember new information, has been associated with long term illicit cannabis use but has been shown to be reversible after a period of abstinence.
  9. Long-term heavy cannabis smokers have increased risk of pulmonary symptoms such as chronic bronchitis and COPD but have no increased incidence of lung cancer


As expected, cannabis-naïve patients tend to have more frequent adverse side effects compared with regular users. The effects of THC can change over time, with therapeutic effects more resistant to tolerance development than side effects. Careful attention. to appropriate dosage, delivery method, and ratio of cannabinoids can reduce many of their adverse side effccts.


It is important to point out that the adverse effects of medical cannabis cannot be equated with the adverse effect of illicit marijuana use. The amounts and ratios of the different cannabanoid constituents vary dramatically between different marijuana plants, whereas medical marijuana is formulated with specific standardized doses and ratios of the different cannabinoid component. The use of illicit marijuana does not allow for any accurate prediction of dosing.


Interactions With Other Drugs and Herbal Preparations

Cannabinoids and Opioids

There appears to be a synergistic analgesic (pain-relieving) benefit when cannabanoids are added to opioid treatment for pain in which there is a greater-than-additive benefical effect with the addition of cannabinoids. Studies indicate a trend towards reduced use of opioids when patients taking opioids add cannabinoids to their regimen. It is not uncommon for patients started on cannabinoids to be able to taper off opioids.


Interestingly, animals studies suggest that cannabinoids may reduce the development of tolerance to the analgesic benefits of opioids, resulting in less need for opioid dose escalation.


There is no enhancement of cardiorespiratory suppression from opioids with the addition of cannabanoids due to the very low density of cannabanoid (CB) receptors in brainstem cardiorespiratory centers. There does not appear to be any significant interactions with opioids regarding a cannabinoid effecct on opioid metabolism.

For more information, See Cannabinoids and Opioids


Alcohol and Benzodiazepines

The combination of cannabinoids with alcohol and benzodiazepines may increase sedation and cognitive impairment.


NSAIDS (Non-Steroid Anti-inflammatory Drugs)

NSAIDs such as ibuprofen and naproxen, particularly indomethacin, can suppress the effects of THC.


 Anticholinergic drugs (Tricyclic antidepressants (TCAs) and some muslce relatxers)

Medications with anticholinergic activity such as amitriptyline (Elavil) and doxepin, and muscle relaxers such as cyclobenzaprine (Flexeril) may increase the psychoactive side effccts of cannabanoids.


Herbal Preparations

Sedative agents such as sleep aids (includes supplements containing GABA, melatonin, 5-HTP, skullcap, or valerian) – Use caution when taking these products and cannabis products together because one may experience increased drowsiness.


Drug Metabolic Interactions

The major cannabanoids, THC and CBD are both metabolized in the liver by the CYP450 enzymes 2C9 and 3A4. Drugs that inhibit these enzymes may enhance or prolong the effects of THC and CBD. Whether people with genetic variants of these enzymes may experience altered effects from cannabinoids is not known. 


The bioavailability of medications are generally described in terms of maximum blood level (Cmax) and maximum overall absorption into the blood (AUC).


Metabolic Effects of Medications on Cannabinoids

CYP3A4 Inhibitors Effect on Cannabinoids

Treatment with CYP3A4 inhibitors such as ketoconazole can produce an increase in Cmax and AUC of THC (1.2- and 1.8- fold, respectively). The increase in Cmax and AUC of the primary active metabolite of THC, 11-OH-THC,  can be 3 and 3.6-fold, respectively, and of that of CBD (2- and 2-fold, respectively). Therefore, if concomitant drug treatment with CYP3A4 inhibitors (e.g. itraconazole, ritonavir, clarithromycin) is started or stopped during treatment with cannabinoids, a dose adjustment may be required.


CYP3A4 Inducers Effect on Cannabinoids

Treatment with CYP3A4 inducers such as rifampicin can reduce the Cmax and AUC of THC (by 40% and 20%, respectively), the primary active metabolite of THC, 11-OH-THC, (by 85% and 87%, respectively) and CBD (by 50% and 60%, respectively). Therefore, concomitant treatment with strong enzyme inducers (e.g. rifampicin, carbamazepine, phenytoin, phenobarbital, St John’s Wort) should be avoided whenever possible. Again, if concomitant drug treatment with CYP3A4 inducers (e.g. itraconazole, ritonavir, clarithromycin) are started or stopped during treatment with cannabinoids, a dose adjustment may be required within two weeks of starting or stopping the inducer.


Metabolic Effects of Cannabinoids on other Medications


CBD has been identified as a potent inhibitor of CYP2D6 which may have significant impact on the metabolism of medications that are broken down by CYP2D6, including hydrocodone (Norc0, Vicodin, Zohydro, Hysingla). As such, use of CBD with tramadol, codeine or hydrocodone may significantly reduce the analgesic effectiveness of these opioids.


CBD is also a potent inhibitor of CYP3A enzymes, especially CYP3A5. While CYP34 is the dominant CYP3A isoform in the metabolism of most drugs, some drugs such as diltiazem, are more efficiently metabolized by CYP3A5 than by CYP3A4. Also, CYP3A5 is a major isoform of CYP3A found in extrahepatic tissues and plays an important role in the metabolism of endogenous and exogenous compounds in these tissues. Thus, the inhibition of CYP3A5 by CBD may cause interactions with other medications but may also disturb normal metabolism of endogenous compounds.


Since cannabinoids are readily distributed in various tissues due to a high lipophilicity, tissue concentrations of CBD may be even higher than the blood concentration, suggesting that the inhibition of human CYP3A by CBD might be caused during and/or after marijuana smoking.



As of February, 2018, medical marijuana prices from licensed producers in Canada ranged from $4.25 to $15 per gram. Public Safety Canada reports the average price from licensed producers to be $8.37 per gram. Given that most patients smoke 1 to 3 g per day (compared to the recommended 400 mg per day), typical costs are approximately $250 to $750 per month.

No cost estimates for Louisiana are available at this time.


Botanical Cannabis

Botanical cannabis is highly inconsistent and variable in its chemical composition. Some authorities describe Cannabis as a single species, while others describe up to four separate species: Cannabis sativa, Cannabis indica, Cannabis ruderalis, and Cannabis afghanica (or kafiristanica). Cannabis likely evolved in Central Asia, native to regions including Afghanistan, Pakistan, India and China.  Cannabis species have been found to fall into three general chemotypes (chemical compositions) based on genetically-determined THC:CBD ratios:

  1. Category I: Relatively high total THC and low total CBD
  2. Category II: THC:CBD ratios near equal (1:1)
  3. Category III: Relatively low total THC and high total CBD


While native Central Asian cannabis is mostly chemotype III (CBD- dominant), emerging commercial cannabis over the last few decades such as currently grown in Washington are more likely to fall into chemotype I (THC- dominant). While there still are biochemically distinct strains of Cannabis, the Cannabis sativa amd Cannabis indica distinction is commonly debated in the laymen’s literature with alleged differences in their constituent combinations and therapeutic effects. Sativa is often described as being uplifting and energetic, whereas indica as being relaxing and calming. At this time, however, due to the evolution of commercial breeding the distinction between the two, as one expert put it “is total nonsense and an exercise in futility.” One can no longer assess the biochemical content of a given Cannabis plant based on its height, branching, or leaf morphology. Due to the degree of interbreeding and hybridization, currently only a biochemical assay can accuratey identify what is really in the plant.


However, no universal standards for laboratory testing protocols currently exist, and there is controversy as to whether all reported results are legitimate. A 2018 study investigated the consistency of reported cannabinoid content of legal cannabis products from state-certified laboratories in Washington. The study  documented significant differences in the cannabinoid content reported by different laboratories. It was reported that there is relative stability in cannabinoid levels of commercial flower and concentrates over time. This publication underscores the need for standardized laboratory methodologies in the legal cannabis industry to provide a framework for quantitatively assessing laboratory quality.


THC and CBD concentrations depend not only on the species and strain, but also cultivation, growth conditions, harvesting and storage of the plant. The average contents of THC, CBD, and CBN in dried plant preparations of marijuana confiscated from 1993 to 2008 in the United States were 4.5, 0.4, and 0.3%, respectively, although these contents varied widely. In marijuana resin, commonly referred to as hash or hashish, the average contents of THC, CBD, and CBN are 14.1, 2.5, and 1.9%, respectively. However, in the decade following 2008, various strains and marijuana-based products contain substantially higher contents of these constituents, especially THC which can range upwards of 20-30% or more.


Aside from the increasing number of CBD predominant strains introduced in the market recently, almost all Cannabis currently are high-THC strains. While the strength and ratio of THC and CBD play a large role in the clinical effects of marijuana, a synergy exists between these two components and their combination with other constituents that produce effects that are uniquely determined by the amount and ratios of all the constituents. In addition to THC and CBD, there are other cannabinoids in cannabis including tetrahydrocannabivarin (THCV), cannabigerol (CBG) and cannabichromene (CBC), as well as other pharmacologically active chemical constituents including cannabis terpenoids that impact the clinic effects of marijuana.


Cannabis terpenoids include limonene, myrcene, a-pinene, linalool, b-caryophyllene, caryophyllene oxide, nerolidol and phytol. These terpenoids are derived from a shared precursor with the cannabinoids, and are all flavour and fragrance components common to human diets that have been designated “Generally Recognized as Safe” by the FDA. Terpenoids are quite potent and affect behaviour when inhaled even at very low levels. Terpenoids have unique therapeutic effects that likely contribute to the synergy or “entourage” effects of cannabis with respect to treatment of pain, inflammation, depression, anxiety, addiction, epilepsy, cancer and infections.


In all likelihood, the differences in observed effects in Cannabis are due to their terpenoid content, which is rarely assessed or reported to potential consumers. The sedation of the so-called “indica” strains is often wrongly attributed to CBD content when, in fact, CBD is stimulating in low and moderate doses. Rather, sedation in most common Cannabis strains is attributable to their myrcene content, a monoterpene with a strongly sedative effect that resembles a narcotic. In contrast, a high limonene content (common to citrus peels) will be uplifting on mood, while the presence of the relatively rare terpene in Cannabis, alpha-pinene, can effectively reduce or eliminate the short-term memory impairment classically induced by THC.


This complexity of cannabis constituents and their pharmacologic impact underscores the importance of pharmaceutical medical marijuana in which pharmacologic agents are manufactured with specific doses and ratios which allow for safer titration of dosing to achieve desired clinical benefits.
