Ritalin is damn good for studying on, which is one of the reasons I (was) looking for a cheap distro (used my $1.5 dollar contact for a new shipment).

Sigh, guess I have to get it myself..

Novartis Ritalin at the bottom, Queteset Ket gram bags on the right, the rest you can probably guess.

That odd red packaging at the bottom is Buprenorphine (Temgesic).

Sugar, although not an according to Hoyle stimulant, it acts in the same way as one by releasing energy quickly into the system.
(I think..my expertise is not in Biochemistry, although it should be Pharmacology).
