SWIM noticed that atropine and cocaine have a bicyclic cicloaliphatic ring system, made with two rings condensed. One chair conformation 1-methyl-piperidine, condensed with a cyclopentane system. That is tropane, isn’it? Well, you find tropane both in cocaine and atropine. The difference is that in cocaine there are an alcoholic and a carboxylic acid functions on two adjacent carbon atoms, saturated as esthers (on hydrolysis of coke you should obtain that bicyclic ring system + benzoic acid and methanol), while in atropine there is just one alcoholic function, exactly in the same C atom as cocaine, estherified with tropic acid. Well, if one extracts atropine out of Datura Stramonium, obtainable any-fucking-where in these summer periods as an infestant weed, then hydrolyses it to liberate that tropanic ring system, followed by an estherification with benzoic acid, you should obtain a product structurally very similar to cocaine, the only difference is that is lacking a methyl esther carboxyl group. Has this way tried before? If this stuff could be any good, there is a shitload of these plants now, and in the evening hours, the smell of toxic they exhale can be felt metres away; it’s a pity they thrive so happily and useless!
