Desoxyn is routinely prescribed to teenagers with severe ADHD. It is literally just methamphetamine tablets. Oral capsules with pure methamphetamine crystals. Like Panzerchokolate, or whatever the WWII Germans called it. Or Pervatin as it was called for the front line troops. Some soldiers had crazy psychotic experiences with those pills and barely made it back alive.. There's also the modern much more common Vivance extended release pills. Marketed as less addictive and extended release, but people still use them to get high. Of course the most common are the extremely popular amphetamine pills; Adderall. Take a few or sniff a line of one and you will be up for three days straight, same as that dirty street meth... But it was prescribed by a doctor!!
