How would you define abuse, and what contribution do you think laws can make toward preventing such abuse?
Let's see, it if increases cognition after a long night, or during a long night there are going to be some who will attempt to overdose.
Just look around, it happens.
It looks like from what I've seen, however, that there is a huge safety margin between projected dose and limiting doses with an ampakine (CX-717) so you'd probably have to take 8 pills or more to just develope a headache!
But right now there's nothing to suggest that abuse (taking more than the recomended dose) would do much more than produce a headache.
Further testing will tell. We're a couple of years from having an ampakine on the shelf for anything. But DARPA (military) and sleep related uses are probably going to come first.
LAWS? Just distribution/costs will limit use, as it USUALLY should be.
