Why bother with cold turkey when you can just get a vaccine? Medical researches are testing radical new drugs which would allow smokers to immunize them against cigarette addiction.

MSNBC notes, "If it works — and this has not yet been proved — the vaccine could become part of a new generation of smoking cessation treatments. They attack dependency in the brain instead of just replacing the nicotine from cigarettes in a less harmful way, like the gum, lozenges, patches and nasal sprays sold today."
