You have lots of rights not specifically mentioned in the Constitution. In fact the Framers were so concerned about this point being spelled out so no one could make any mistakes about it they included this:
Amendment the Ninth: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
There's no explicit Constitutional right to drink alcohol. But when we banned that the 22nd Amendment had to be ratified and the Volkstead Act passed.
Drugs support an underworld of evil and hopelessness and ending the "drug war" will only allow more victims to be dragged into the pit.
Which is exactly what happened after Prohibition ended. We're now a nation awash in hopeless alcoholics dying on every streetcorner.
Oh, that never happened? Sorry.
Have a good day.
It makes me sad that people who claim to be conservatives twist their logic to rationalize drug use as "personal responsibility". Delusion.
