Petition Ban Smoking in front of minors (under 18s)

Banning smoking in front of minors will protect the children of this country from the harmful effects of passive smoking as well as helping to prevent the psychological link to smoking caused when children see others smoke.
If children arent around smoking at all they will be less likely to smoke themselves.
My biggest fear is that my child grows up to become a smoker.
Are we doing enough to prevent the next generation of smokers?
I want the government to make smoking infront of children or in the vacinity of children illegal.
This includes in cars and outside shops, pubs, resteraunts, bus stops, and everywhere else where smoking can affect children via passive smoking.
