Anti-smoking drugs

There is positive feedback on two anti-smoking drugs.

One is Varenicline. The drug targets the area of the brain affected by nicotine. A review of 5,000 smokers found the drug increased the odds of quitting three-times for a year or longer.

Another study found the antidepressant drug Zyban can double a person's chances of quitting.

Both studies are published in the Cochrane Library.
