It's good to point out that amphetamines are not the only treatment for ADHD nor are they always the best treatment. In fact Methylphenidate (Ritalin) is a Norepinephrine-Domamine Reuptake Inhibitor, which while still having dopaminergic effects on the brain, are not amphetamines and can't really even be detected through traditional urinalysis means.

So those of us who do take Methylphenidate and are subject to regular urinalysis to measure amphetamine content as a requirement to obtain a prescription renewal for the drug in the US, are actually being tested for additional non-perscription use of amphetamines unrelated to our ADHD treatment. I feel this should be illegal and that Methylphenidate should really be removed from the list of controlled substances.
