Types vary: The conservative half-life for the general class of amphetamines is 32 hrs. That means that 50mg taken will leave 25mg in your system after 32 hrs. Another 32 hrs and 12-1/2 remain, etc. So, how much matters. A tiny, tiny bump will leave a tiny, tiny, tiny bump. Helpful? Not much, I guess. Don't use it. It's really a BAD thing for our bodies. Drinking is fine, but 'drunk' is not great either.
