What is THC?

We all love our beloved herb, cannabis, but do we know what it is and how it works in the body? To begin, THC, or tetrahydrocannabinol, is one of the 100+ known compounds found in the cannabis plant.

THC is a cannabinoid. Another cannabinoid you might recognize is CBD.

THC is the compound that provides the cannabis user the psychoactive feelings.

Strongest Marijuana Strains to Smoke

THC affects both the mind and body through a little-known system called the Endocannabinoid System. The endocannabinoid system regulates bodily functions and works with homeostasis to keep equilibrium within the body. It is crucial for your body that these two are functioning together, as they keep all of your vitals stable. The ECS helps to regulate memory, pain, motor controls, digestion and inflammation.

There are specific receptors within the system, the CB1 and the CB2 receptor, that are working to keep the above functions at bay. THC has an affinity to the CB1 receptor, found in large quantities in the brain. When THC binds to this receptor, it creates intoxicating effects and also mimics a natural chemical called anandamide, also known as the “bliss” molecule. THC can create feelings of euphoria, altered time and perception, lightheadedness, relaxation and sensory changes.

It is important to realize that receptors are like fingerprints, meaning they are unique for everyone.

This explains why everyone has a very different reaction and feeling to THC.
