The SmokeFree campaign poster aims to persuade people to quit smoking and raise awareness of the dangers of smoking through graphic imagery and facts. The poster uses a graphic image of mutations on a cigarette to visually portray the damage smoking can cause. It also includes a fact about how just 15 cigarettes can negatively impact health to catch viewers' attention. The poster provides links to SmokeFree websites to give people seeking help resources to quit smoking. The goal is to campaign against smoking by informing people of its health risks in an eye-catching way.
