>The only caveat is that methamphetamine should remain illegal to buy or use. The idea being that people will use "less harmful" drugs than methamphetamine because they are available cheap, easy and clean. The strongest possible justification for legalization of sale and use of drugs is to minimize usage and supply of the greatest of all evils - methamphetamine.

You seem to have an oddly demonized view of methamphetamine. The reaction on people is fairly similar to dextroamphetamine, which you probably know of by the name of 'Adderall', and we prescribe it frequently.

Meth is mildly neurotoxic and adderall is not, so it's definitely worse for you, but we let people do plenty of things that are bad for them.

Not that I'm suggesting anyone go out and develop a meth habit, but if you're arguing in favor or legalizing everything but meth you're already arguing in favor of quite a few things that can cause personal damage.

The violence surrounding meth is much the same as the violence surrounding most other illegal substances - driven by the actions taken to procure funding of the substance or procuring the substance itself.
