I think potheads are pathetic, but that’s a completely different matter than whether or not I think they should be crushed by the federal government. Justice Thomas made the right call in Gonzales v. Raich.

In a federalist system, we permit other states and people to decide how they want to live even if we disagree with them. For one thing, that means we can live together peacefully as one nation. For another, it means the states are free to experiment and maybe prove or disprove the value of a given policy, like the legalization of marijuana.
I agree. I believe it should be left to the states.
