A smoker is more likely to kick the habit if a spouse, friend, co-worker or sibling did..


May 22, 2008 -  A team of researchers who showed that obesity can spread person-to-person ( NEJM 357(4):370-379, 2007) has found a similar pattern with smoking cessation. Not surprisingly, the greatest influence was seen in close relationships. When a spouse stops smoking, the other partner is 67 percent less likely to smoke. Similarly, when a friend quits, the odds of the other continuing drops by 36 percent. The odds are similar among co-workers and siblings. The findings back up previous studies showing that peer influence plays a key role in people's decision to stop lighting up and provide evidence that the "buddy system" used by smoking cessation, weight loss and alcoholism programs to change addictive behavior works.
