Topical Marijuana Products
Topical use of marijuana products are as of yet not well explored but cannabis-based formulations offered currently appear to provide therapeutic benefits. As research and experience grow, it is expected that even greater benefits particularly for joint and muscle pain will be available. Currently available products are explored here along with a brief review of the mechanisms by which they offer their benefits.

Topical Products
Marijuana-related medications act on the body primarily through the Endocannabinoid System (ECS), a nerve/hormone system present all throughout the body (See: Endocannabinoid System) . These actions are primarily carried out via the medications interacting with cannabinoid receptors associated with the ECS. There are several different cannabinoid receptors in the ECS, but the CB1 and CB2 receptors are the best known.
CB1 receptors are mostly found in the nervous system but are also found to a lesser extent in the skin. Tetrahydrocannabinol (THC) interacts primarily with the CB1 receptors. CB2 receptors are mainly found in the skin, organs and immune cells. and respond indirectly to cannabidiol (CBD), as well as other cannabinoids and terpenes (especially β-Caryophyllene). Topical marijuana products act mostly through the CB1 and CB2 receptors in the skin because they do not penetrate systemically to reach the brain. Therefore they can be therapeutically effective without the intoxication, euphoria or sedation associated with the systemic exposure that is associated with ingesting or inhaling marijuana products.

Transdermal vs Topical
Transdermal medications are designed to penetrate the skin barrier in order to provide systemic (whole body) benefits. By penetrating through the epidermis, the topmost layers of the skin, and into the underlying dermis layer where the blood vessels are, transdermal products are transported through the blood to the organs and especially the central nervous system including the spinal cord and brain where cannabinoids provide therapeutic benefits.
Topical formulations, on the other hand, refers to creams, lotions, ointments, and other products designed to be massaged into the epidermis only. These products target the skin itself to provide benefits only locally to the area of application. They don’t carry cannabinoids into the blood vessels of the derma below and therefore are not meant to enter systemic circulation.
Topical marijuana based products can be helpful for arthritic joint pain, tendonitis, muscle soreness, tightness and spasm, headaches and skin conditions such as such as eczema and psoriasis. Products with β-Caryophyllene may also help with sensitivity to cold as well as the nerve pain associated with peripheral neuropathy or with injured nerves including chronic regional pain syndrome (CRPS).
LA Topical Marijuana-Based Products
In LA, currently available topical preparations are formulated with absorption enhancers to facilitate transdermal penetration. The extent to which these LA topically applied THC products actually enter the blood and become available to enter the brain and central nervous system is unknown but they are not promoted as transdermal preparations and they do not seem to provide much, if any, psychoactive effects or other systemic benefits. However, this means that the THC is likely to trigger a positive urine drug screen.
Currently available topical preparations are provided in 2 oz jars or 50 ml pumps and are typically applied to affected areas 1-4 x/day. These products have generally been reported by patients to be helpful for pain, especially joint pain but also neck and back pain.
It should be noted however that these products all contain THC in significant amounts which contributes to their relatively high cost. Studies are lacking as to whether the THC components of these creams are truly important in their contribution to the therapeutic effects of these products. Alternative over-the-counter products with CBD and terpenes (but no THC) are also available at significantly less expense yet they may offer equivalent or superior benefits. No head-to-head studies have been performed comparing benefits of THC-based formulations vs. CBD/terpenes only-based formulations.

Marijuana (Cannabis): Topicals (coming soon)
Topical marijuana products currently available are provided in four THC/CBD formulations:
Illera Topical Products:
Wellcana Topical Products:
Wellcana topicals reportedly have a variety of sources for their constituents but do include a signifcant contribution from the Jenny Kush strain of cannabis which contains pinene, caryophyllene and limonene. No additional information as to other constituents in their products is available.
