Does Smoking Calm Anxiety? What Nicotine Does to Your Brain

The cigarette with your coffee seems to calm you down, but in reality it is putting out a fire it started itself. We explain what nicotine does to your brain and which three aids work best to help you stop smoking.

What nicotine does to your brain

When you inhale, nicotine reaches the brain in about ten seconds. There, it fits into certain receptors like a key in a lock.

That binding releases dopamine in the nucleus accumbens, the part of the brain that learns what is worth repeating. With daily use, the brain adapts and produces more receptors.

Why a cigarette seems to calm you

After a few hours without smoking, those empty locks start demanding their key. Irritability, anxiety and difficulty concentrating set in.

That is the trick. Each cigarette delivers less and less pleasure and more and more relief. What it actually does is bring the smoker back to the baseline a non-smoker enjoys for free. The brain mistakes that relief for calm.

Does quitting smoking increase anxiety?

During the first few weeks, yes. But a 2021 Cochrane review found that, over time, people who quit smoking had less anxiety, depression and stress than those who kept smoking.

On top of that, this relief comes at a high price. According to the WHO, tobacco kills more than eight million people a year. More than one million of them die from breathing other people's smoke.

Two myths about tobacco

Myth one: smoking a little is harmless. It isn't. An analysis published in the BMJ in 2018 calculated that smoking one cigarette a day carries between a third and half of the excess coronary risk of smoking twenty.

Myth two: vaping helps you quit. The WHO does not consider it a proven method for stopping smoking. It also keeps nicotine dependence going.

The three aids that work best for quitting smoking

1. Nicotine replacement therapy. Patches, gum or lozenges provide nicotine without smoke, so withdrawal is less intense. They are available from pharmacies. The patch covers the whole day, and gum helps with sudden cravings, for example after coffee. Used together, they work better than either one alone.

2. Professional support. Book an appointment with your doctor or a nurse at your local health centre and explain that you want to stop smoking. They will help you set a quit date and plan for high-risk moments, such as lingering at the table after a meal or stress at work.

3. Prescription medicines, such as varenicline. It acts on those same receptors and partly occupies the lock. This eases cravings and, if you slip up, the cigarette is less satisfying. Combined with professional support, it can as much as double your chances of success. Your doctor will assess whether it is suitable for you.

When to see a doctor

Some warning signs should not be ignored: a cough lasting more than three weeks, coughing up blood, or new shortness of breath. If you have any of these, see a doctor.

If you take any medication, tell your doctor before you quit. Smoke changes how some drugs are cleared from the body, and the dose may need adjusting. Never do this on your own.

In short: that cigarette doesn't calm you. For a few minutes, it gives back the calm it took away from you.
