That type of “logic” only makes sense IF you are stoned - something I am not.
To me it is a state issue, and it makes no never mind to me if states do or do not legalize it - I would like to see the feds butt out. It took a constitutional amendment for the feds to institute prohibition for alcohol - I see no difference between alcohol and marijuana, thus do not understand why the feds are involved in it at all, unless in the same manner.
A state can have prohibition but if cartels want to pour drugs into the state, you need fed gov to guard borders and stop the flood.
