Some smokers seem to.
Although the risks of smoking have been very well publicized, a recent survey conducted by Boston researchers found that smokers don't seem to recognize the health risks they face. Only 40 percent of smokers thought their habit raised their risk for cancer, and only 29 percent realized they had an increased risk for a heart attack. One reason many smokers fail at quitting or don't even try to quit is the fear of gaining weight. It's common for smokers to put on weight once they quit. But researchers in Israel have found that it is possible to limit the amount of weight gain.
