A friend once told me that it was 100 times harder for him to quit smoking cigarettes than to quit drinking alcohol. He was successful and hasn’t smoked a cigarette for over 10 years, but he’s a lucky minority. I have several other friends who still struggle with smoking cigarettes – willpower, counseling, exercising, nicotine replacement patches and antidepressants like Zyban haven’t been enough.
Clearly nicotine is highly addictive. About 45 million people in the U.S. smoke cigarettes, even though cigarette smoking leads to 1 of every 5 deaths each year. In a National Health Interview Survey, over half of the smokers reported trying to quit in the past year without success.
In the future, these smokers may get a vaccine to help protect them from nicotine addiction.
Researchers from Weill Cornell Medical College and Scripps Research Institute have developed a new vaccine that may treat nicotine addiction, by blocking the pleasurable sensations that nicotine creates in the brain. Dr. Ronald Crystal and his colleagues have demonstrated that they can prevent nicotine from reaching the brain in mice using a single injection of vaccine. If these findings are confirmed in people, this vaccine could be an effective therapy to help prevent nicotine addiction.
