"We discussed the effects of hallucinogens in a previous lesson. Recall that hallucinogens alter perceptive and emotional faculties. This class of drugs includes marijuana, psilocybe, LSD, mescaline, and PCP. Common side effects include anxiety, panic, loss of coordination, nausea, increased body temperature, delusions, and hallucinations. In the following slides, we'll provide more detail on the use and abuse of marijuana, the most widely used hallucinogen in the United States. We'll also discuss more generally dissociatives and the prototypical hallucinogens, which have importantly different effects."
