Adults should be free to do as they wish, even if they make choices that other people don’t agree with.
If you don’t agree with alcohol use, tobacco use, pot use, or hard drug use, than don’t use them.
Overturning Wickard v Filburn would have ramifications well beyond pot prohibtion, and drug laws in general. Great swaths of federal bureaucracy would suddenly have no claim of constitutional authority.
So an adult should be free to attack from me and rob me?
