Do you support repealing the 21st Amendment, and returning to the days of moonshine, speakeasys, and Al Capone? After all, ending Prohibition validated the "alcohol culture", didn't it?
The "drug culture", as you describe it, started long before the 1960's: it started in the 1930's, with the first generation of Americans that relied on the welfare state for assorted and sundry government handouts. Marijuana isn't the enemy - socialism is.
