Time to prohibit chewing gum?

As chewing gum will always get dropped and stuck on pavements by a minority, is it time to prohibit chewing gum sales in the UK/EU? Singapore banned it back in 1992, the ban remains to this day (although medicinal gum is allowed). I wouldn't miss it, and it would not be "nanny state" ban. In fact, dog dirt is just as much a problem, if only the culture would change, and owners would tidy up after their pooches!
