If you believe in the constitution then you have to believe that the government has no right to stop someone from using drugs. I mean if you break the law like drive while drugged up do some other crime then you will go to jail. Right now we have a lot of junkies in jail on minor crimes and our jails are getting full! I’ve been at the juncture to legalize all drugs and tax them. This could kill the illegal drug trade. They could use the tax money to help people get off of drugs.
Then build more prisons.
They could use the tax money to help people get off of drugs.
This is your idea of conservatism?
The legal question to ask is not one of usage, but of possession. Can the state or federal government regulate what a citizen possesses, whatever it may be. If the answer to that is yes, then your constitutional argument falls apart.
