Why do people take LSD?

LSD, like other hallucinogens, produces a distortion in the user’s sense of reality, including images, sounds, and sensations that do not really exist. These hallucinations can be pleasurable and for some people even intellectually stimulating, but they can also be disorienting or disturbing and result in a negative emotional experience (bad trip). It is difficult to determine what kind of an experience a person will have on LSD because the same person can have very different experiences each time. As with all drugs, but especially with LSD, a user’s experience is shaped by her previous drug experience, expectations, setting, as well as the neurological effects of the drug.
