What didn’t work for alcohol will work for easily concealed drugs like cocaine or heroin or meth? Let’s not kid ourselves.
You should read your own words. You’ve nailed my whole argument in a nut shell. What didn’t work for alcohol hasn’t worked for drugs like cocaine, or heroin or meth or pot, i.e. prohibition.
Then allowing each state (or worse, the local level) to decide if drugs should be legal isn’t the solution. Why did you even suggest that when you now admit you know it wouldn’t work?
