Quitting smoking is one of the hardest things to do, but studies have found that one strategy in particular can help many people: Start anti-smoking medication well before your intended quit date. Under traditional prescribing guidelines, people who plan to quit smoking with the help of a medication begin taking their anti-smoking drug about one week before their set quit date. But about 75 percent of people who try to quit go back to smoking within a year.
So what's the solution? Research done at the University at Buffalo, in New York, showed that simply starting the drugs four weeks in advance can increase the success rate. One study was done on bupropion, known by the brand name Zyban, and similar research has involved both nicotine replacement therapy and varenicline (Chantix).
