How vaping affects men’s health

6 min

Strong public health campaigns and strict regulation have seen rates of tobacco smoking almost halve over the last three decades in Australia. However, the number of people vaping every day has grown from 6% in 2016 to 9% in 2019 – a trend that’s sounding alarm bells for many health experts.

Here’s what you need to know about vaping and what the evidence so far shows when it comes to men’s health.

What is vaping?

E-cigarettes (you might know them as e-cigs, electronic nicotine delivery systems (ENDS), vapes, or by their brand names, like Juul) are battery-powered devices that heat up liquid to make a vapour you inhale.

When e-cigarettes first became available, vaping liquids contained nicotine and a range of chemicals to add flavour, but as of October 2021, all nicotine vaping products can only be purchased with a doctor’s prescription.

Nicotine-free devices and e-liquids can still be legally bought in most parts of Australia.

A 2019 study found that 60% of “nicotine-free” liquids contained nicotine, however, follow-up research in 2021 found nicotine was detected much less frequently and in lower concentrations.

Is vaping harmful to your health?

There’s not enough evidence to be sure that vaping is safe. We can’t be sure, but it looks like vaping makes lung function worse and affects wound healing2.

Because many diseases take a long time to develop, and long-term studies on the health effects of using e-cigarettes aren’t available yet. It’s important to remember that just because there is currently no proof that vaping causes disease, this is not proof that it is safe.

Is vaping better for you than smoking tobacco?

Vaping is often marketed as a better alternative to smoking cigarettes. When e-cigarettes are used by smokers instead of conventional cigarettes there is evidence for improvement in individual health[2]. However, many people who use e-cigarettes also smoke cigarettes, and diseases caused by smoking are unlikely to be reduced by e-cigarettes if you continue to smoke3.

If you start vaping, you’re three times more likely than non-vapers to take up smoking tobacco later on[3].

While two out of three long-term smokers in Australia will die from smoking, quitting before 45 years old can reduce your mortality risk close to that of never-smokers [4] but how this might be affected by vaping is not known.

Does vaping help smokers quit?

Quitting smoking can be difficult, so the best option is not to vape or smoke at all. Many people use e-cigs to try and stop smoking, to reduce the number of cigarettes smoked, or to avoid restarting a smoking habit when they quit.

Ex-smokers who use nicotine e-cigarettes are more likely to not smoke than those who use other nicotine replacement options such as patches, gum, lozenges, mouth sprays, inhalators, and intranasal sprays[5]. However, most studies showing this effect have a moderate or high level of bias and more research is needed.

Most published studies of e-cigarettes were funded or otherwise supported by manufacturers of e-cigarettes (including the tobacco industry), which appeared to influence the conclusions[6].

Key Australian health organisations such as the Australian Medical Association, Cancer Council Australia and the Australian Council on Smoking and Health, say there isn’t enough evidence to promote the use of e-cigarettes for smoking cessation. You may be able to use nicotine e-cigarettes as a last-line tool for quitting smoking but only under medical supervision if your doctor thinks it’s right for you.

Vaping and erectile dysfunction

Men have long been more likely to smoke than women and younger men who have higher psychological stress and are current smokers are more likely to use e-cigarettes[7]. There’s plenty of evidence to suggest nicotine impairs normal erectile function and negatively affects male sexual performance. Erectile dysfunction is twice as common among men who vape every day, compared to those who have never vaped[8].

The bad effects of conventional cigarette smoking on men’s reproductive health are proven but more research on vaping’s impact is needed.
