> Raising the cost of tobacco has over half the effect of getting people to quit or never start. Also very important is banning smoking in public places and hard-hitting, scary, advertisements spending about $1 to $2 per capita. Clinical interventions such as doctors speaking with patients about quitting, providing nicotine replacement therapy, and telephone counseling support are also important. But most of the gains are from the public policy initiatives.

Statistically, empirically, which of those things actually work? I've heard time and time again that scary ads don't seem to do a damn thing, while raising prices actually seems to have an overly large impact.
