Total bans on products people use and can enjoy responsibility due to potential health risks is nearly always a bad idea in my opinion. Just look at smoking in the US, for example, which recently hit an all time low. We could have gone the prohibition route (and we can guess how that would turn out), but instead we clamped down on advertising, increased taxes, and helped usher in a societal change where smoking is largely seen as unacceptable behavior by huge swaths of people now.
