Has anyone out there experienced REAL, long-lasting hallucinations after smoking up? Some intrepid psychonauts I know experimented with shavings of Datura leaf in their mull and had what they variously discribed as 'otherworldly' and 'near-death' experiences that sometimes lasted for hours. The comedowns usually included brutal headaches. Frightened shit out of me so I stayed away from it. Being an imprecise and undoubtedly dangerous 'science ' I DON'T advocate mixing poisonous plants with perfectly good bud, but I am curious to hear from people who do.
