As interpreted by our court judges.
Federal & state drug ~prohibition~ laws do not so comply on any number of grounds.
Then do drugs and see if the courts will save you from going to jail.
Reasonable law ~regulating~ the commercial sale & public use of mind altering substances on public health & safety grounds are perfectly constitutional, as you well know, as per alcohol.
Test it in the courts. I'll stand back and watch.
Which leaves this question. -- Why do you support unconstitutional prohibitionary type laws, -- laws which in their enforcement are destroying the very principles our free republic is built upon?
Our republic wasn't built on drug freedoms any more than it was built on the right of people to have sex in public.
You're the one that believes that states don't have the right to outlaw drug use, aren't you. So much for the myth of "state's rights Libertarians". LOL
