Libertarians will also make rational arguments about how blood alcohol limit laws should be repealed. After all, there's no science to indicate that 10 different people will be impaired to the same extent by the same blood alcohol level.
My point is simply this: now you're trying to convince sensible people of two things they've been trained not to believe. First, that something that has been a controlled substance for decades should be open to commerce in California, and second, that the basis of our drunk driving laws are unsound and should be in effect repealed starting with that controlled substance.
A campaign to repeal blood alcohol limits would almost certainly fail in every US state, so its attachment to this bill seems like a horrible overreach.
No, that issue is solved. It's called a trial.
