April 20. On this date celebrating cannabis culture, it is worth reflecting on 'Abdu'l-Bahá's words: "Regarding hashish, you had pointed out that some Persians have become habituated to its use. Gracious God! This is the worst of all intoxicants, and its prohibition is explicitly revealed. Its use causeth the disintegration of thought and the complete torpor of the soul. How could anyone seek this fruit of the infernal tree, and by partaking of it, be led to exemplify the qualities of a monster? How could one use this forbidden drug, and thus deprive himself of the blessings of the All-Merciful?"

1184. The Use of Marijuana, LSD and Other Psychedelic Products
"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.
"Although we have found no direct reference to marijuana in the Bahá'í writings, since this substance is derived from what is considered to be a milder form of cannabis, the species used to produce hashish, we can share with you a translation from the Persian of a Tablet of Abdu'l-Bahá on hashish:
'Regarding hashish, you had pointed out that some Persians have become habituated to its use. Gracious God! This is the worst of all intoxicants, and its prohibition is explicitly revealed. Its use causeth the disintegration of thought and the complete torpor of the soul. How could anyone seek this fruit of the infernal tree, and by partaking of it, be led to exemplify the qualities of a monster? How could one use this forbidden drug, and thus deprive himself of the blessings of the All-Merciful?...
'Alcohol consumeth the mind and causeth man to commit acts of absurdity, but ... this wicked hashish extinguisheth the mind, freezeth the spirit, petrifieth the soul, wasteth the body and leaveth man frustrated and lost.'"
(From a letter of the Universal House of Justice to the National Spiritual Assembly of the Hawaiian Islands, November 11, 1967)
