What I do think is happening is physicians who are not acutely aware of some of the risks of amphetamines are treating their patients with other drugs, let's say antidepressants. The sad fact is probably half the people prescribed an antidepressant don't get a satisfactory result. So amphetamines get added to the mix in hopes of enhancing the antidepressant effect or in hopes that they will counter some of the side effects.
