LSD
From Bahai9
LSD is included under the prohibition in the Kitáb-i-Aqdas of opium[edit]
"Heroin, hashish and other derivatives of cannabis such as marijuana, as well as hallucinogenic agents such as LSD, peyote and similar substances, are regarded as falling under this prohibition."
- (Notes to the Kitáb-i-Aqdas, no. 170)
LSD should not be used except if prescribed for medical treatment, nor should Bahá'ís become involved in experiments with LSD[edit]
"In reply to your request of October 24, 1967 that we issue a statement concerning 'the use of marijuana, LSD and other psychedelic products', we have already informed the National Spiritual Assembly of the United States that Bahá'ís should not use hallucinogenic agents, including LSD, peyote and similar substances, except when prescribed for medical treatment. Neither should they become involved in experiments with such substances.
