You have no regard for common adult humans. That adult human is our 'present', you are worried about kids that is our 'future'.

Help the adult smokers first, kids later.

You said ''You can ruin your own body, but at least give your own child a chance.''

This is very unfortunate on your part for not caring the adult smoking parent, who is always a kid for his own parents. So you carelessly want to sacrifice some body else's kid and save your own kid ???
