Why Does High THC Matter?

High-THC cannabis strains

tetrahydrocannabinol (THC)

THC is the most prevalent active ingredient and psychoactive compound in cannabis. It is commonly associated with a “high” effect after a few cannabis hits, but the impact goes beyond psychoactivity.

THC activity starts in the ECS, your brain’s network of enzymes, receptors, and endogenous cannabinoids (eCBs) responsible for various cognitive and physiological processes in the brain and body.

THC can mimic eCBs and bind to receptors, mainly CB1 and CB2, prevalent in the central nervous and immune systems, respectively. As a result, various brain regions may be affected, and functions such as motor control, mood, memory, reward, and appetite may be stimulated.

THC also affects the hypothalamic-pituitary-adrenal (HPA) axis and alters cortisol levels in the body. All these stimulate the stress response, hormone secretion, and growth and sex hormones.

The list could go on and on shaped by other factors like route of administration, dose, and frequency of use.
