Make smoking around others outside or in public without other's consent illegal (i.e. you can complain to police if you don't like the smell), and introduce a rule you can only smoke on licensed premises (with smoking rooms) or at home.
That's what some places have done with tobacco smoking. It is basically harassment or assault in my view to have people consume your second hand smoke and smells.
Edibles on the outer hand, or if you create flavored vapes that don't smell much or travel far in the air, all good.
Lack of creativity among conservatives is never surprising.
Also it's already illegal for kids to do weed, smoke or drink.
