It's used as leverage by vicious parents. Unfortunately for my ex idiot, I smoke outside. Bf loathes cigarette smoke.
I've read about other cases where that has been the situation.
Also, the anti-smokers are targetting seperated/divorcing parents. One group even offers, for a fee, a "kit" on how to win a custody battle when the other spouse smokes.
Money and control are the only 2 things that interest the professinal anti-smokers.
It is a shame that so many otherwise intelligent conservatives fall for the nonsense.
