You get like 200 mg per foot of cactus, if your a noob like me. I bet an expert chemist could not get much more. a gram...maybe? .....I found a extract on RIU that claims to get a good trip with just two shots of tea. one shot for threshold and three for full blown. I could handle a couple shots no problem. drinking a cup sucks..... and I think mescaline give you the shits just like LSD or even MDMA. could be a diet thing mixed with the anticipation of the oncoming trip that upsets ones stomach? Anyhow, i will try to boil the tea dow. with this new tech and get so e tea leafs for practice. ,.... I hate giving up on anything. I want to make sure, at the very least, that i learned a simple A/B extraction....
