You can have a society that says "drugs are not OK", but which does not confiscate a man's real estate because unbeknownst to him, someone lit up a joint in one of its rooms.
1) A Police State is a bad thing. Our war on drugs is prosecuted badly. I do not like quasi-military forces kicking in doors. I do not support property seizures. These are bad attempts to enforce a law.
2) I would support legalization of drugs -- but only after Government charity is ended. If you can be responsible and support yourself AND take drugs, then it is none of my business. BUT the current situation is that a lot of feckless people get in trouble with substance abuse -- and they use MY money to survive. I will support legalization AFTER people become free to die in alleys due to their bad decisions. Until we live in such a free country, I think making drugs illegal isn't so bad.
