> I don't even try to use amphetamines for productivity anymore because they don't clear from my system fast enough to avoid interfering with my sleep.
Some people have told me that they prefer cocaine to amphetamine specifically for this reason: its metabolic half-life is something like two hours, if I recall. Have you tried using cocaine instead? I'm not sure if the toxic side effects are more or less severe; maybe you know.
(Myself, I stay far, far away from the entire family of stimulants. The most I take is caffeine, and then only in the traditional drink forms, not in pill form.)
I wouldn't want to try and use cocaine to focus. While I've tried it once, I don't like the typical routes of administration, the lack of quality control, and financially, supporting the drug cartels.
The only drug I use regularly is caffeine, also (coffee) =).
Hmm, I think most people who take cocaine just chew coca leaf, which eliminates all three of your concerns. There may not be any people taking cocaine by that route anywhere near you, though.
