THC as lung-cancer treatment?
Some evicence suggests that THC, the (psycho-) active ingredient in cannabis may be a useful treatment for lung cancer.
THC acts on pair of receptors, CB1 and CB2. The receptors are found in the brain and peripheral tissues; CB1 activation in the brain is responsible for the psychoactive effects of the drug, CB1 activation in the circulation causes a decrease in blood pressure, and CB2 is involved in modulating immune function.
