No, they don't. Methamphetamine and amphetamines are quite different. Methamphetamine is neurotoxic and crosses the blood brain barrier at twice the rate that amphetamines do. Equating the two is misleading, wrong, and will create stigma

Methamphetamine hydrochloride IS methamphetamine. I don't know how that can be stated more clearly.

Edit: in addition they are very much the same. They cross the b/b barrier at different speeds (add mentioned) and are metabolized at different rates due to the additional methyl group but otherwise their pharmacological actions are very much the same. The differences in effects are almost entirely covered by the 2 potentially mentioned rates differences. To argue otherwise is to ascribe produced sociological effects which we create by now we treat the drugs to their inherent pharmacology which is just plain wrong.

Note that absorption and metabolization rates can affect the safety profile; for example, this is why acetaminophen is generally safe at lower doses, but quickly becomes hepatotoxic at higher doses, because different metabolic pathways come into play:

Methamphetamine by itself isn't neurotoxic, but the additives it is commonly cut with usually are.
