For example, cheap distilled spirits have little or no redeeming value. But it would be more harmful to make that illegal than otherwise. Methamphetamine (Desoxyn) is used to treat obesety and ADHD, and similar treatments for ADHD have similar potential for recreational use/abuse. But the whole Drug War is so harmful, it doesn't matter if there are therapeutic or harmless recreational uses of a drug. It would be less expensive, more effective, and more compassionate to treat addicts than to continue the Drug War, even if more people became addicted.

Palliative care, for one.

> Meth

FDA-approved to treat ADHD and obesity. Lots of people use amphetamines to great effect when working/studying.

> Cocaine

Used as a local anesthetic in nose surgery.

In addition, one might argue they pick a person up when they want to be up and relax them when they need to relax and abuse, not use is the problem. I'm not saying this argument is correct, but these drugs, like other drugs, have their uses. Which is why people use them.
