Want to improve your mood? Quit smoking
Conventional wisdom says many smokers use cigarettes to ease anxiety and depression. But a new study has shown that quitting makes people happier.health and fitness Updated: Dec 03, 2010 13:34 IST
In the new study, researchers tracked the symptoms of depression in people who were trying to quit and found that they were never happier than when they were being successful, for however long that was.
Based on their results, the authors recommend that smokers embrace quitting as a step toward improving mental as well as physical health, said Christopher Kahler, corresponding author and research professor of community health at the Warren Alpert Medical School of Brown University.
Quitting is not, as some smokers may fear, a grim psychological sacrifice to be made for the sake of longevity.
"The assumption has often been that people might smoke because it has antidepressant properties and that if they quit it might unmask a depressive episode," said Kahler. "What's surprising is that at the time when you measure smokers' mood, even if they've only succeeded for a little while, they are already reporting less symptoms of depression."
Kahler and colleagues from Brown, The Miriam Hospital, and the University of Southern California studied a group of 236 men and women seeking to quit smoking, who also happened to be heavy social drinkers.
They received nicotine patches and counseling on quitting and then agreed to a quit date; some also were given specific advice to reduce drinking. Participants took a standardized test of symptoms of depression a week before the quit date and then two, eight, 16, and 28 weeks after that date.
All but 29 participants exhibited one of four different quitting behaviors: 99 subjects never abstained; 44 were only abstinent at the two-week assessment; 33 managed to remain smoke-free at the two- and eight-week checkups; 33 managed to stay off cigarettes for the entire study length.
The most illustrative - and somewhat tragic - subjects were the ones who only quit temporarily. Their moods were clearly brightest at the checkups when they were abstinent.
After going back to smoking, their mood darkened, in some cases to higher levels of sadness than before. The strong correlation in time between increased happiness and abstinence is a tell-tale sign that the two go hand-in-hand, said Kahler, who is based at Brown's Center for Alcohol and Addiction Studies (CAAS).
Subjects who never quit remained the unhappiest of all throughout the study. The ones who quit and stuck with abstinence were the happiest to begin with and remained at the same strong level of happiness throughout.
The study has been published online Nov. 24 in the journal Nicotine and Tobacco Research.
