The big difference between them is that THC causes a ‘high’ feeling or psychoactive effect, whereas CBD is known for its potential health benefits.
Marijuana and hemp are both members of the cannabis plant family, but the ratio of chemicals inside them differs.
Marijuana contains a very high amount of the THC compound, the illegal substance that causes people to become ‘high’ and a small amount of CBD.
Hemp is the opposite, containing a very high concentration of CBD and a low amount of THC.
Legally, CBD products must be derived from an industrial hemp strain to ensure that the THC amount is not over 0.2%.
