Most students know about harmful effects of smoking cigarettes including the risk of cancer, stroke, heart disease, breathing problems (1). Students may also know that stopping smoking reduces these health risks (2-3).
Most people may not know that smoking contributes to anxiety and depression and that you can feel good and increase happiness by quitting smoking.
This study (4) analyzed mental health inforation across 26 studies and looked at positive and negative changes in mental health before and after quitting smoking cigarettes.
What did the study show?
When compared to smokers, 7 weeks to 9 years after quitting smoking, those who quit smoking reported a DECREASE in:
• Mixed anxiety and depression
When compared to smokers, 7 weeks to 9 years after quitting smoking, those who quit smoking reported an INCREASE in:
• Psychological quality of life 0.22 Positive affect significantly 0.40
• This improvement occurred whether or not participants had anxiety or depression before quitting smoking.
But I thought people smoke to be less anxious and depressed?
• When they have not smoked for a while, smokers experience irritability, anxiety, and depression (6, 7)
• These feelings are relieved by smoking (5) thus creating the perception that smoking has psychological benefits, while in fact it is smoking that caused these psychological disturbances in the first place.
How can I quit smoking?
You may want to talk to your doctor/prescriber about medications and nicotine replacement as additional options that can help you quit.
Is smoking worth anxiety, depression and feeling bad? Is it zapping your energy level? How good will you feel after you stop smoking for good?
