I too would probably say I was in favour of a stupid policy on drugs, meaning going on as we are now. Perhaps, if I were daring, I might admit that change may be possible in the future. But I would be crazy to argue in favour of the reform that our drug laws so badly need. It would lose me a lot of votes, and the only television programmes it would get me on would be the ones about freaks.
Ordinary voters are scared of drugs and dislike drug users.
Changing the present policy of drug prohibition is easily misrepresented by demagogues as going 'soft on drugs'. The very idea of lifting the drugs ban calls up instant resistance from the moral guardians in the churches and so on. And the one change worth making is counterintuitive, involving intricate and painful explanation. So here goes. The only sound policy for mind-altering drugs is to bring the trade in them within the laaw, so that they can be taxed, controlled and discouraged.
