Abstract
There are various types of hallucinogenic drugs that are distinguished by the psychological effects which they induce. The most familiar are the “visionary psychodysleptics” which produce prominent visual and somatic distortions and hallucinations. Complex emotional changes ranging from ecstasy to terror may occur, as well as alterations in thinking. Examples of such drugs are LSD, mescaline, and tryptamine derivatives such as dimethyltryptamine (DMT). The imagery-producing psychodysleptics such as cannabis and various coumarins (e.g., from Calea zacatechichi) potentiate visual imagery and produce characteristic distortions in time perception, body-image, and thought. Trance-producing psychodysleptics (such as lysergic acid amide (obtained from Rivea corymbosa) ololiquhqui, turbicoryn, and corymbosine), as their names suggest, produce trance-like states. Finally the deliriants (e.g., atropine) produce clouding of consciousness and amnesia, as well as hallucinatory effects.
