Psychoactive Alkaloids and Psychedelic Effects

Psychedelic compounds are known to produce powerful effects on the mind, and they have been used throughout history for spiritual and medicinal purposes. One of these compounds is mescaline, which is found in high concentrations in the San Pedro cactus (Echinopsis pachanoi).
