Nowadays, consuming marijuana is not only knowing the name of the strain you’re buying, it also means to understand their components and what they can cause in your body. To start that process, is necessary to understand the difference between CBD and THC.

What’s the difference between CBD and THC?

Marijuana has more than 100 components, however, the more famous are CBD and THC, those two are also identified as cannabinoids. Both CBD and THC have the exact same molecular structure: 21 carbon atoms, 30 hydrogen atoms, and 2 oxygen atoms.

CBD, aka, cannabidiol is extracted from the flowers and buds of marijuana or hemp plants.This component doesn’t have psychoactive effects.

The effectiveness of marijuana is explained by the existence in the human body of an “endocannabinoid system”, constituted by neurotransmitter substances -such as serotonin or anandamide- and its cellular receptors that regulate a variety of functions, such as: sleep, appetite, the pain or the immune response.

Therefore, the CBD works essentially as naturally as a substance secreted by the body itself.

THC is the main therapeutic agent in the most commonly used cannabis preparations.
