Now you're talking about an argument from efficacy, not liberty. My point is that the argument from liberty isn't going to get a good hearing when drug addiction is such a major societal problem. No one cares about your right to get high when drugs are destroying people's lives and entire communities. Drug policy will be judged mostly on its efficacy in preventing and ending addiction and wanton self-destruction.

I would rather say that it's argument from evidence, but that's perhaps an academic point.

But I disagree that drug policy is judged on the merits you mention; we have evidence of decriminalization in portugal, and its relative success in preventing destruction. Meanwhile elsewhere in the world there is very little appetite to entertain the idea of decriminalization or legalization, despite evidence supporting the theory that prohibition exacerbates the effects its intended to directly prevent.
