Never tried modafinil but I've tried a lot of amphetamines, methamphetamines, cathinones, and some other research chems. I can say with confidence that Adderall (d-Amph) is dirtier than d-MethAmp. Meth would work much better for the children but no one would prescribe desoyxn in this day and age, and they only come in 5 mg pills. But I imagine Modafinil as a "wakefulness enhancer" feels like 1 lvl up from coffee and a cigarette.

As an aside I've never touched coke, crack, bath salt blends, or most nootropics
