> Also, Adderall (Amphetamine) != Methamphetamine. That is like saying Ethylene Glycol (a common car anti-freeze) is the same as Ethanol (drinking alcohol) or that Peroxide is the same as distilled water. In fact, the substances I listed above are more molecularly similar than methamphetamine and amphetamine.

The people I know who have made such a distinction haven't done both. The people I know who have done both tell me that they have essentially the same effects.

> Also, stimulant medications have a higher safety profile than many OTC medications, so take that for what it's worth.

Yeah, I think a lot of OTC medications are essentially grandfathered in to drug policies and would require a prescription if they came out new today.
