Amphetamines like that will do more harm than good and it’s not really a stable high as far as drugs go. Plus, testing coke is a pain as you don’t really know what it is cut with.

Yeah, of course. Amphetamines can be used medicinally, but it’s better they be amphetamine salts and are used on a regular schedule. I have been taking Adderall for years, and after so long, it’s a chore to constantly use them. Also, the long term side effects absolutely suck ass. They work, but I would rather not take them any more.
