In some schools or army.
In Estonia, cases like this occur in most of russian schools. In russia, I think that's a standard. My father started smoking in 4th grade... Today, he doesn't have a choice, though he's been fighting for 46 years. And won for some durations, too.
But you can research for more yourself.
Taking a smoke or getting yourself beaten up, abandoned and bullied for rest of your time in place doesn't really sound like two fair options to anyone.
