"LSD, or acid, is derived from a fungus that grows on grains such as rye. It is typically used for its ability to cause delusions, hallucinations, and an altered sense of time and self. LSD increases body temperature and heart rate, and causes loss of appetite, sweating, sleeplessness, and shaking. Peyote is a cactus containing mescaline, a chemical with effects similar to those of LSD, but with different types of hallucinations."
