@microRNA Yes, but not just for decriminalizing possession as in Portugal. The entire chain from customer to manufacturer.The key thing in an extra-legal market, it can mostly supervise itself because there are clear standards for drug purity, drug manufacture standards etc. The only criminal activity, is those cow-boy operations that persist in dangerous manufacture practices, lie about their product or use violent practices to obtain customers etc.Instead of organizations like the DEA, we'd have the drug market equivalent of a 'Food Standards Agency', with inspectors investigation operations and giving out licenses to operate. Similarly, there would be certain restrictions on the point of sale. e.g. not to minors etcYou don't necessary have to get the drug from decent operators with a certificate, but you'd be well advised to.In such a world, the vast majority of the black market would become grey. Not illegal or legal, but outside the law, extra-legal. Here society isn't validating your drug use, they were merely putting up with it and defining a valid route.I don't have all the answers, but there's some ideas there. I think it's best to experiment and see what works best rather than bumbling along in the dark into perpetuity. We're never going to get rid of some form of government interference, and we're never going to get rid of drug markets, so we might as well come to some clearly defined solution so harm reduction is at its most optimal.
