Effects of LSD and Psilocybin in Controlled Experiments

The study reviews a number of controlled experiments that observe the effects of common psychedelics, specifically LSD and psilocybin. These drugs have been associated with increases in mood, sociality, and empathy, as well as the recognition of negative affect. In these studies, small doses—such as 100-200 mcg of LSD and 15 mg of psilocybin—have been dosed according to body weight.
