That is a strawman hypocrite you’re attacking. Regulation of drugs and criminalization of drugs are two different matters. I hardly see antiprohibitionists go after regulations on food production or distribution in the same terms as they do the War on Drugs, though they may attack it also. Not in principle, except on federalism grounds, but for more technical reasons.
Drugs can be regulated like that, according to legitimate state interest. In the same way that selling tainted fruit can be stopped bu state authorities, but possessing a banana is not criminal.
You still make no sense.. Drugs can be regulated? Ok. Well, lets keep it how it is with alcohol and tobacco legal and the rest not. Ok? Seems like a reasonable compromise to me.
