they're hesitant because they're whipped by the ugov. amphetamines decided wars. us airforce liked having it around because it's the alpha substance. international substance control was implemented afrerwards to make sure only very few countries could get it, and you have to have a handler to do so as well. it's most effective when you avoid sin. also, op's picrelated contains the l-isomer, that is, the sinister isomer. dextro, the right isomer, is the move. i hypothesize that street meth is such a problem because it's 50/50 dextro and sinister. the sinister isomer in adderall persists longer than the dextro, and i wouldn't be surprised if meth was the same way. presumably, people who get the prescription meth (which is 100% dextro) don't go nuts because they aren't getting overloaded by the sinister isomer.
