For the reader, that's not only an apt analogy - it's a chemically accurate one. Structurally the difference between methamphetamine and amphetamine as well as between ethanol and methanol is a methyl group.

Pharmacologically it's a different story - methanol is not a safe substance with any dose.

Addendum: This isn't to imply that methamphetamine has dosage that eliminates its side effects and neurotoxicity, but rather that drinking methanol will quite easily make one go blind.

It's only now, several hours later, that I realize I meant to have written 'adderall'. Good grief.
