Marijuana vs. Hemp

What is the difference between Marijuana and Hemp?

 
The short answer is that they are quite different, with distinct difference in appearance, growth patterns, legal implications and, especially, pharmacologic properties. For more about the differences between marijuana and hemp, see below.

Marijuana vs Hemp

Within the kingdom of plants, the Cannabaceae family includes the genus Cannabis; included in this genus are Cannabis ruderalis (hemp) along with the marijuana subspecies cannabis sativa and cannabis indica, each of which have multiple varieties. In turn, each variety has its unique content of pharmacologically active agents including the cannabinoids THC, CBD and others. Since hemp and marijuana both derive from the Cannabis genus, they do share certain similarities. However, due to each plant’s biological structure, they have several very distinct and crucial differences.

 

Appearance

Hemp has skinnier leaves, concentrated at the top with fewer branches aand leaves at the lower part of the plant. While marijuana looks like a short fat bush, hemp is typically skinnier and taller (up to 20 ft).  Hemp and marijuana clearly look very different from one another.

 

Chemical Makeup

The main difference between hemp and marijuana is there chemical composition, specifically in their tetrahydrocannabinol (THC) content. THC is the cannabinoid compound responsible for marijuana’s psychological effects along with many of the medical benefits. Marijuana generally contains anywhere from 5-20% and even up to 25-30% THC content. Hemp on the other hand, has a maximum THC content of only 0.3% or less and as such, hemp offers no “high” effects. However, hemp like marijuana does contain other cannabinoids, especially cannabidiol (CBD).

 

Legality

As a result of paranoid and uninformed politicians including President Nixon and the “War on Drugs,” hemp was initially grouped with all Cannabis species and banned in 1970 as a Schedule I Drug under the Controlled Substances Act. In most of the United States, the allowed THC-content for hemp to be classified as legal is 0.3%, while in much of the rest of the world, the allowed THC-content is 0.2%. Because it contains minimal THC, hemp is now legal to grow and is used in many industial applications such as paper, clothing, building materials, biofuel, food products, oils and more. Because of its high CBD content, hemp is also used to produce a wide variety of THC-free CBD pharmaceutical products.
