yeah basically, i have yet to try mescaline. i am considerably comfortable with acid and shrooms by now so im not new to the whole psychedelia thing. My question is basically, how much fresh san pedro cactus will i need to extract a reasonable amount of mesc. If i am going to be going through the whole extraction process, i want it to be for more than 1 dose. How much cactus would i need to extract say 4 or 5 doses? I know potency varies, so just an estimate wuld be good. Also does anyone know of a good UK vendor. Cheers
