vaping about…….A major review on the health effects of e-cigarettes reflects what public health advocates have feared – escalating use of e-cigarettes in school-aged children, early warning signs of increased smoking rates in young Australians, and direct health harms of vaping in all ages. The review, which was released today, was commissioned by the federal health department and conducted by researchers at the Australian National University. Overall, it found the health risks from e-cigarettes significantly outweighed any potential benefits. The review should silence lobbyists, who have long used data selectively to promote the sale of e-cigarettes. This is despite the fact previous reports, none as comprehensive and rigorous as this latest review, have delivered similar findings. What does the review tell us? The review looked at the evidence behind the health impacts of e-cigarettes or “vapes” – a diverse group of devices that aerosolise a liquid for inhalation. These are touted as a safer alternative to cigarettes and an aid to quit smoking. The review found conclusive clinical evidence e-cigarettes cause acute (short-term) lung injury, poisoning, burns, seizures, and their use leads to addiction. They also cause less serious harms, such as throat irritation and nausea. Evidence e-cigarettes produce airborne particles in indoor environments (potentially harming non-users) was also conclusive. Among evidence ranked as strong, the review confirms what has worried tobacco control experts since patterns of e-cigarette use first emerged. People who have never smoked or are non-smokers are three times as likely to smoke if they use e-cigarettes, compared with people who have never used e-cigarettes. This is a dream for tobacco companies and their retail allies. Weighing up the harms and the benefitsThe review found limited evidence e-cigarettes assist individuals to stop smoking. But this is no stronger than evidence showing e-cigarette use might also cause former smokers to relapse and revert to tobacco. There is no conclusive or strong evidence in the review for any beneficial outcome from e-cigarettes. E-cigarettes might help some individuals stop smoking. So they should only be available via a prescription from authorised medical professionals trained in helping people to quit. Any access beyond this risks serious harm for no benefit.

This has risen from 19.2% in 2016 to 26.1% in 2019. Of e-cigarette users who identify as smokers, the second largest user group is 14 to 17-year-olds. Dual use is starting young, from the limited Australian Institute of Health and Welfare data we have.
