The Brain of a Smoker

We’re all well aware by now of the dangers of smoking when it comes to respiratory and cardiovascular health. However, it also has a profoundly negative impact on the body as a whole, including the health and proper functioning of the brain. Today, we’re going to shed light on what occurs within the brain of a smoker and provide yet more reasons to never take it up, or to kick that habit for good.

Smoking in young people

When we’re discussing smoking and brain health, it’s important to note the impact that it can have on a developing brain. Our brains are still maturing into our mid to late 20’s, and smoking can cause immense disruption to these crucial processes. In fact, some studies have shown that younger smokers are more likely to have reduced brain volume in several key areas, including emotional regulation, impulse control, and decision-making. 

Smoking in general

Not only does nicotine create feelings of pleasure by activating dopamine signals, it also mimics several neurotransmitters, thus increasing overall signaling within the brain. In response to this, the brain compensates by reducing the number of acetylcholine receptors. Acetylcholine is the principal neurotransmitter of the parasympathetic nervous system and is responsible for a diverse range of brain and body functions, from muscle movement to memory.  

Smoking and cognitive decline 

Now let’s think about more of the long-term effects of smoking. Perhaps unsurprisingly, it accelerates brain aging, stunts cognitive function, and comes with a higher risk of dementia, as well as an increased chance of strokes, cancers, and cardiovascular issues. Research looking into the structural brain changes in smokers has noted that they have thinner cerebral cortexes and less grey matter. And what does this mean in real terms? Memory and learning tasks become much more difficult. 

Smoking and mental health

Although some people use smoking as a way to temporarily reduce anxiety or stress, mental health issues can often worsen as a long-term result. Since nicotine has mood-altering properties, it creates a dependence that, over time, can compound conditions such as depression, and even increase the chances of developing schizophrenia. 

How to quit for good using brain-friendly methods

If you smoke currently and have found that traditional methods of quitting aren’t working for you, then perhaps tuning into what your brain needs could be the answer. What do we mean by this? Well, instead of flooding your system with dopamine via cigarettes or vapes, take the time to show your brain new ways of receiving a steady supply. For example, engage in regular exercise, prioritize sleep, try meditating, and take a look at your diet. Remember, every small change adds up.
