Do you feel the same way about the states' ability to regulate the legalization of marijuana?
I thought I already answered this question. I'll be happy to answer it again.
As with any law, absent Congressional action, the state has the power to regulate the commerce in their state. They can prohibit the sale of sex toys, for example. Since Congress has chosen to regulate marijuana, the states are bound by the Supremacy Clause of the U.S. Constitution to comply.
Are you saying that, despite federal action in this area, states should still be allowed to regulate marijuana as they please?
