I you are a smoker, how do you tell your kids not to smoke?

Nooooooo don't just "let them".... tell them all the reasons they should not smoke...... educate them...... don't let them smoke if they are underage either. If they are going to make that decision they should do so being informed and of the legal age. Best thing to do is to quit and show by example.

Its hard to tell your kids not to smoke especially if you are smoking. Parents usually idolizes their parents and they usually copy what their parents are doing.

If I have a kids I will tell him to not smoking. but I will also let him choose he want to smoke or not. it he's life not mine..

I will not impute to my kids if they are smoke, but they have to reach enough age for that, like 17 years old or older, because i ever feel the situation like them, as long as it is the real smoke, not mariyuana smoke hehe
