Although the number of adults smoking in the UK has decreased since 2011, there are still around 6 million people who smoke in the UK. Smoking kills one person every five minutes according to analysis released on World No Tobacco day by Cancer Research UK in 2023.
Smoking can have a negative impact on your mental health, and statistics show that those with anxiety, depression or schizophrenia are more likely to smoke than those without these conditions.
The addictive affects of nicotine on the brain
Nicotine, an addictive drug used in tobacco, is one of the main reasons people struggle to quit smoking. Nicotine triggers the release of dopamine in the brain, causing a temporary ‘pleasurable’ feeling.
Over time, you can grow an intolerance to nicotine, meaning you require more amounts in order to feel a temporary pleasurable effect.
