After finishing this chapter, students should be able to understand:
Hallucinogenic plants have been used for many centuries, not only as medicines
but for spiritual and recreational purposes as well.
LSD, a synthetic hallucinogen, alters perceptual processes and enhances
emotionality, so that the real world is seen differently and is responded
to with great emotion.
Other chemicals that contain the indole nucleus, such as psilocybin (from
the Mexican mushroom), have effects similar to those of LSD.
Mescaline, from the peyote cactus, and synthetic derivatives of the amphetamines
represent the catechol hallucinogens. They have psychological effects quite
similar to those of the indole types.
MDMA is the only catechol hallucinogen that appears likely to be capable
of producing permanent brain damage in its users.
PCP, or angel dust, produces more changes in body perception and fewer visual
effects than LSD.
Anticholinergics are found in many plants throughout the world and have
been used not only recreationally, medically, and spiritually but also as
poisons.
