Roscoe. I don't care if every person in the US but one has decided that prohibiting a thing is ok, it's not allowed. At least to the federal government. If you want the federal government to have that power, then enact an amendment giving it that power, and get it ratified.. They used to understand that, thus the 18th amendment giving congress the power to prohibit alcohol. Remember how well that worked? The same thing is happening again, but without the legitimacy of a constitutional amendment.
There is no such power in the Constitution to prohibit a thing. Period, end of discussion. Even if 99.999999999999% of the population agreed with you, they still would not have the power unless an amendment was passed and ratified under the procedures specifically set out in the Constitution.
It is folks like you, along with your hubris and paranoia, who are tearing this nation apart. You say...oh no, a nasty plant that will make someone happy....must eraticate it and jail all who may get the slightest enjoyment from it...can't have enjoyment, oh no.
God, listen to yourself, Roscoe. You must a bitter, unhappy man.
Two centuries of building the greatest, most free and prosperous nation in history abandoned in favor of the unsubstatiated ravings of America hating zealots promoting Constitutional revisionism? You don't stand a chance.
