The review also confirmed that psilocybin, a compound contained in some species of mushrooms, significantly helped in the treatment of depression and cancer-related anxiety. Other promising, though more preliminary, results suggests that the hallucinogenic drug LSD (lysergic acid diethylamide) and a plant-based brew [...]
