Smoking, mental health and dementia
How does smoking cause stress?
Smoking cigarettes interferes with certain chemicals in the brain. If you haven’t had a cigarette for a while, the craving for another one can makes you feel irritable and anxious.
These feelings are relieved for just a short while when you smoke a cigarette. But this relief doesn’t last long, your body soon starts to crave another cigarette, making you feel irritable and anxious again – you might even feel your heart rate and stress levels rising. Over time people who smoke are more likely to develop anxiety and depression than people who do not smoke.
Mental health benefits of quitting
People with mental health problems – and those without – report that they feel much calmer, more positive, and have a better quality of life after stopping smoking. The effect has been proven to be similar to taking antidepressants.
When people stop smoking, studies show:
- anxiety, depression and stress levels are lower
- quality of life and positive mood improve
- the dosage of some medicines used to treat mental health problems can be reduced
How can I make quitting less stressful?
If you want to stop smoking, contact your local stop smoking service which will provide support to quit.
Stop smoking treatments like nicotine replacement therapy (NRT) or vapes can really help with cravings. A trained stop smoking advisor can talk about the different stop smoking aids and help you decide which will work best for you. They can work out how best to manage your cravings before they pass.
If you take medicines or antidepressants, you must talk to your GP or psychiatrist to get advice on the amount you need to take.
It’s a myth that smoking helps with stress. Quitting can reduce your stress and anxiety.

Smoking and dementia
None of us like to think about developing dementia. But evidence is clear that smoking raises the risks of developing dementia.
- Smoking increases the risk of vascular problems which affect blood vessels and can lead to strokes or smaller bleeds in the brain. These increase the risk of dementia.
- Poisonous chemicals in cigarette smoke cause inflammation and stress and kill off brain cells and neurons, which increase the risk of Alzheimer’s Disease.
Alzheimer’s Research UK advise: “evidence is that stopping smoking reduces your risk of dementia. This is similar to other findings with smoking, where stopping smoking leads to a reduction in the risk of cardiovascular disease or cancer.”
