Since I am not a smoker, it is hard to tell which is the best way to quit smoking cigarettes is. However, I do believe these posters create some sort of awareness, am not sure to what extend is the effect but definitely on a minute scale.
Quit smoking hypnosis, pill, drugs, hypnotherapy, patch and many more simply does work. Ever heard of electronic cigarette?
An electronic cigarette (or “e-cigarette”) is an alternative to smoked tobacco products, such as cigarettes, cigars, or pipes. It is a battery-powered device that provides inhaled doses of nicotine by delivering a vaporized propylene glycol/nicotine solution. In addition to nicotine delivery, this vapor also provides a flavor and physical sensation similar to that of inhaled tobacco smoke, while no tobacco, smoke, or combustion is actually involved in its operation.
