I have been asked about almost every supplement, cream and pill you can buy online. I have almost never been asked about cigarettes. That says a lot. Men will spend money on a mystery capsule from an advert, and the whole time they are holding in their hand one of the most clearly proven enemies of a good erection.

I am not a doctor, and this is not medical advice. The facts come from the NHS and studies listed on PubMed. The opinions are mine, from 14 years in an industry where how your body performs is literally your job.

Why your erections are a blood vessel story

To understand why smoking matters, you have to understand what an erection is. When you are aroused, nerve signals tell the arteries in your penis to relax and widen. Blood rushes into the spongy tissue, the tissue swells, and the veins that would let the blood out get compressed. The result is an erection.

The key word is widen. Your arteries need a healthy inner lining, called the endothelium, that can release the chemical signals (mainly nitric oxide) that tell the vessel to open. The arteries in the penis are small, much smaller than the ones around your heart. So when the endothelium is damaged, the penis often shows it first.

This is why doctors call erection problems an early warning sign. The NHS lists smoking, alongside drinking too much alcohol, being overweight, high blood pressure and diabetes, among the physical causes of erection problems (NHS: erectile dysfunction). Smoking damages the lining of the blood vessels and helps build up fatty deposits that narrow them. Nicotine itself also tightens blood vessels in the short term.

I explain the food side of the same story in the diet for erectile health. Cigarettes are the opposite of that diet.

What the big studies say about smoking

You do not have to trust my opinion. In 2013, researchers pooled the data from eight observational studies with a combined 28,586 men in a meta-analysis published in PLOS ONE (Cao et al., PubMed). They found that:

• Current smokers had about 51% higher odds of erectile dysfunction than men who had never smoked.
• Former smokers still had about 29% higher odds, which suggests some damage can last.
• The risk tended to rise with the number of cigarettes and the years of smoking.

These are observational studies, which means they show an association, not a perfect proof that the cigarette alone caused every case. Smokers may also drink more, exercise less or have other risk factors. But the biology is clear, the pattern repeats across countries, and that is why every serious medical source tells men with erection problems to stop smoking.

You cannot out-train or out-supplement a pack a day. The arteries keep the score.

Vaping: the new question

Many men I talk to switched from cigarettes to a vape and think the problem is solved. For lungs, vaping is generally less harmful than smoking. The NHS says vaping is substantially less harmful than smoking and supports it as a way to quit cigarettes, while being clear that it is not risk-free and that people who do not smoke should not start (NHS: vaping to quit smoking).

But erections are a different question, because the main problem for blood vessels may be the nicotine itself, and most vapes deliver plenty of it.

In 2022, researchers at NYU Langone published a study in the American Journal of Preventive Medicine using data from the US Population Assessment of Tobacco and Health (PATH) survey (El Shahawy et al., PubMed). They looked at men aged 20 to 65 with no history of cardiovascular disease. Men who vaped daily were 2.41 times more likely to report erectile dysfunction than men who had never vaped, even after adjusting for things like age, smoking history and other health conditions.

The authors themselves pointed out the limits: it was a cross-sectional survey, erectile dysfunction was self-reported, and you cannot prove cause and effect from one snapshot. But it is a serious warning, especially because vaping is popular with exactly the young men who think erection problems will never happen to them. I talk about why that is not true in erectile dysfunction in young men.

So my honest view is simple. If you are switching from cigarettes to vaping to quit completely, that is a step forward. If you are vaping forever and telling yourself it is harmless for your sex life, you are probably wrong.

Does quitting actually help?

This is the good news, and it is the reason I wrote this article. There is evidence that quitting can help erections recover, at least for some men.

In a prospective study published in BJU International in 2004, doctors in Iran followed smokers with erectile dysfunction for a year after they received advice to quit (Pourmand et al., PubMed). Among the men who stopped, at least 25% had improved erections after one year. None of the men who kept smoking improved. The men who benefited were mostly younger and had less advanced vascular damage.

A 2023 review in Sexual Medicine Reviews summarising the evidence on cigarettes, e-cigarettes and erectile function also describes a randomised smoking-cessation study in which 53.8% of men who successfully quit improved their erectile function at six months, compared with 28.1% of those who did not (Sexual Medicine Reviews, 2023).

The message is the same as with every blood vessel problem: the earlier you stop, the more you can recover. If you have smoked for 30 years and already have heart disease, quitting is still worth it for your life, but your erections may need medical help too. If you are 28 and smoking ten a day, you have a real chance of reversing the trend.

The first-cigarette-after-sex myth

Cinema built this image: the couple in bed, the sheets, the cigarette after sex. It was cool for decades. In my world, the reality is less romantic. On a professional set, nobody wants the person they are working with to smell of smoke, and performers who know their bodies tend to avoid anything that makes erections less reliable on the day.

I am not going to pretend every performer lives like a monk. People in this industry smoke, drink and party like people in any industry. But the men who last in this job, the ones who still work after ten or fifteen years, usually treat their bodies like a tool, because they are.

How to quit without losing your mind

I am not a stop-smoking counsellor, so I will point you to the people who are. The NHS says you are much more likely to quit with support than with willpower alone (NHS: quit smoking). In practice, what tends to work:

• Use proven tools. Nicotine replacement (patches, gum, lozenges), prescription medicines and stop-smoking services. Talk to a pharmacist or doctor about what suits you.
• Use the vape as a bridge, not a home. If a vape helps you get off cigarettes, good. Then plan to reduce the nicotine and stop.
• Know your triggers. Coffee, alcohol, stress, the drive home. Change the routine around them.
• Move your body. Exercise reduces cravings for many people and directly helps your blood vessels. I explain the erection side of that in exercise and erectile function.
• Do not panic about weight. Some people gain a little weight when they quit. Your blood vessels still win.

And if erections are already a problem, do not wait until you have quit to see a doctor. Erection problems can be a sign of heart disease or diabetes, and medicines like the ones I describe in Viagra vs Cialis need a proper check before you take them.

Alcohol, cigarettes and the Friday night combination

Many men smoke more when they drink. That is a double hit. Alcohol in larger amounts already makes erections harder, which I explain in alcohol and sex. Add nicotine tightening your blood vessels and you have the perfect recipe for a disappointing night, then anxiety about the next one.

That anxiety is its own trap. One bad night becomes fear, fear becomes another bad night, and suddenly a man who has no real disease thinks he is broken. I wrote about that cycle in sexual performance anxiety. Sometimes the first step out of it is not a pill but simply cutting the drinks and cigarettes that started it.

My take

I meet a lot of men who would do almost anything for better erections. They buy supplements, they watch videos, they ask me for secrets. And many of them light a cigarette while they ask.

If you smoke, quitting is probably the single most powerful thing you can do for your sex life that does not involve a prescription. It is free, it is backed by decades of research and the benefits go far beyond the bedroom. If you vape, do not assume you are safe just because there is no smoke.

In my job, your body is your instrument. In your life, it is too. Treat it that way.
