A new theoretical hypothesis on the mode of action of LSD and other hallucinogens of the indolamine family is proposed. In view of the suggestions that LSD acts both on the 5-HT system as an antagonist and on the DA system as an agonist, we suggest that in addition to 5-HT blocking capacity, LSD and the other indolamine hallucinogens act as MAO inhibitors.
