Personally, I don't have a problem with it. But in a state that deems that to be harmful to your neighbors, you violate their right to determine the standards of which they live by.
Not at all! Nothing forces them to smoke the evil weed or quaff the devil's brew.
I suspect you mean their right to determine the standards I live by, but they have no such right and therefore I cannot violate it.
The theory that there's a such a thing as a "positive right", i.e. a right to order other people around, is false. Such rights amount to little enslavements.
