Smoking and mental health 

Smoking does not help with stress. Stopping smoking can reduce stress and anxiety. 

Many people smoke to cope with stress, anxiety, low mood or difficult emotions. Cigarettes can feel calming in the moment – but the relief is temporary.

Nicotine actually keeps the brain in a cycle of tension and withdrawal which can worsen mental health over time.

Understanding this cycle helps explain why smoking feels helpful while quietly making symptoms harder to manage.

Why smoking feels like it helps

Nicotine changes brain chemistry within seconds. It briefly increases dopamine – the brain chemical linked to reward and relief – which can make you feel calmer and more focussed. 

This effect fades quickly. 

As nicotine levels drop, the brain starts to experience withdrawal. This creates uncomfortable feelings such as:

Irritability and low mood

Restlessness

Poor focus

Lighting another cigarette relieves these symptoms – not because the help stress but because it temporarily removes nicotine withdrawal.

 

In other words, smoking doesn’t solve stress, it relieves nicotine withdrawal.

Smoking and anxiety

Smokers and more likely to report higher anxiety then non smokers. Nicotine stimulates the nervous system, and increases heart rate. While the immediate effect feels calming, the overall pattern leads to changing moods and tension throughout the day.

Smoking and depression

People who smoke are more likely to experience low mood. This is partly because nicotine interferes with the brains natural mood regulation. Over time smoking can increase mood swings and lower how you feel all the time.
