(CBS News) – Trying to quit smoking? It’s tough – studies suggest 70- to 80-percent of people who try to quit smoke within six months.

That’s because nicotine is so addictive, says Dr. Ronald G. Crystal, chairman and professor of Genetic Medicine at Weill Cornell Medical College in New York City. Crystal’s team has announced they’ve successfully tested a new vaccine that may treat nicotine addiction.

Crystal told HealthPop that many stop-smoking campaigns try to attack the source of smoking, cigarettes, but what his team wanted to do was find a way to block the sensation nicotine provides in the brain that makes smoking so addictive.”

His team’s vaccine is described in the June 27 issue of Science Translational Medicine.
