First I've heard of generational ban was in a hundred years old novel from Jack London (maybe an autobiography ? can't remember the name). It certainly was about alcohol, maybe he mentioned tobacco as well, anyway the idea and debate certainly aren't new.

I find bewildering that such concepts are tried only centuries later, and wonder how it comes to be possible. Is it that we can finally enforce them, or that the lobbying have been gradually weakened, or enough data to drive decision, etc. ?
