It is believed by some that calamus is a hallucinogen. This urban legend is based on two pages of a book written by Hoffer and Osmund entitled "The Hallucinogens". The information on these two pages came from anecdotal reports from two individuals (a husband and wife) who reported that they had ingested calamus on a few occasions. None of the components in calamus are converted to TMA (trimethoxyamphetamine) in the human organism. To date there is no solid evidence of any hallucinogenic substances in "Acorus calamus".
