New Anti Smoking Vaccine

Doctors test anti-smoking vaccine

Mickey shouldn't smoke! MADISON, Wis. (Associated Press) -- Doctors are testing a radical new way to help smokers quit: a shot that "immunizes" them against the nicotine rush that fuels their addiction. That pleasurable buzz has seduced Mario Musachia into burning through nearly half a million cigarettes in half a century. Now the Madison man is among 300 people around the country who are testing an experimental vaccine that makes the immune system attack nicotine in much the same way it would fight a life-threatening germ. 

The treatment keeps nicotine from reaching the brain, making smoking less pleasurable and theoretically, easier to give up. The small amount that still manages to get in helps to ease withdrawal, the main reason most quitters relapse. 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.
