Club members were clearly familiar with their pot-smoking literary antecedents. Club founder Theophile Gautier wrote of "pantagreulion dreams" passing through his consciousness.
Gautier formed the club after meeting Dr J Moreau - an expert on the effects of hashish. Moreau wrote about how cannabis allowed one to enter "an in-between land where the external life ends and the internal life begins." Moreau also described hashish as "an intellectual intoxication," preferrable to the "ignoble heavy drunkenness" of alcohol.
