So you're good with alcohol prohibition, got it. how bout cigarettes and other tobacco products? Maybe what your concern is with our government and not with the drugs themselves. You should be free to do whatever stupid thing you want to your own body, that's part of that whole liberty thing that conservatives seem to usually champion.
The legalization of drugs turned into a pipe dream of politicians (local, county and state) dreaming of big tax money falling from the sky in order to keep their big government payroll going.
What people put in their bodies, such as drugs, does have an effect on others. So when an uninsured person overdoses, who picks up the hospital bill? The taxpayer!
