May I ask a question? What the hell do you do with atropine? Idrolizing it and re-esterifying it with benzoic acid is useless, since you can't get a cocaine-like anesthetic, for isomerism problems. Years ago, I wanted to extract the alkaloids out of datura stramonium (jimson weed). I lost somewhere the atropine, so I had the doubt I took the right plant. I drank an infusion of a leaf just to make sure it was datura. The effect was bloody strong and horrible. What a bad experience! I remember at a certain stage of the effect I couldn't swallow any more. I wanted to drink some water because I was feeling my skin burning, and I couldn't drink a drop of water. Then I checked on a pharmaceutical medicine book: I had exactly all the symptoms of a strong atropine intoxication. For Christ's sake, don't do that experience! It is completely different from speed or any hallucinogenic drug. Taken for recreational or entheogenic use, is just poison, not a drug! Don't do it, it makes you feel very bad.
