How Does THC Finish Up In My Hair?

Your physique processes THC and other cannabinoids in complicated techniques, causing cannabinoids and their many metabolic byproducts to finish up scattered all through the body’s various systems.

The physique breaks down cannabinoids in the blood immediately, but not pretty immediately enough—some of the THC molecules uncover their way into the soft tissue surrounding the root of your hair (retain in thoughts, all the action is taking spot beneath your scalp so far).
