E-Zigaretten wirksamer zur Raucherentwöhnung als herkömmliche Nikotinersatztherapie

According to the latest Cochrane study conducted by a public health and health policy researcher at the University of Massachusetts Amherst, nicotine e-cigarettes are more effective in smoking cessation than traditional nicotine replacement therapies (NRT).

Reviewing studies published on the subject in the Cochrane Database of Systematic Reviews, high-quality evidence was found indicating that e-cigarettes, which allow users to „vape“ nicotine instead of smoking it, lead to better chances of smoking cessation compared to patches, gums, lozenges, or other traditional NRT.

In England, unlike the rest of the world, e-cigarettes are embraced by public health authorities as a tool to help people reduce the harm caused by smoking.“

Smoking is the most common cause of preventable diseases and deaths worldwide, leading to more than seven million deaths per year. „Most adults in the US who smoke want to quit, but many find it very difficult,“ said Hartmann-Boyce. „We need a range of evidence-based options that people can use to quit smoking, as some people try many different methods before finding one that works for them.“

Hartmann-Boyce, Cochrane editor, is the lead author of the review, which included 88 studies and over 27,235 participants – an addition of 10 studies since the last update in 2022. Most of the analyzed studies were conducted in the US, the UK, and Italy.

E-cigarettes do not burn tobacco; instead, they heat liquids containing nicotine and flavorings, allowing users to inhale nicotine-laden vapor instead of tobacco smoke. „We have very clear evidence that nicotine e-cigarettes, while not risk-free, are significantly less harmful than smoking,“ says Hartmann-Boyce. „Some people who have not succeeded with other cessation aids in the past have found e-cigarettes to be helpful.“

The analysis revealed that out of 100 people using nicotine e-cigarettes to quit smoking, an estimated eight to ten would likely successfully quit smoking, compared to six out of 100 using traditional NRT and four out of 100 attempting to quit smoking without any support or behavioral assistance. Regularly reviewing smoking cessation studies continues to provide strong evidence that can inform public health policies and strategies, providing people who smoke with better options for quitting smoking for good. Hartmann-Boyce stresses that the public health message, particularly in the US, is nuanced and complex.

While non-smokers should avoid the use of e-cigarettes due to potential health risks, Hartmann-Boyce says some smokers can improve their health and reduce their risks by quitting tobacco with the help of e-cigarettes.

„Not everything is completely harmful or beneficial,“ says Hartmann-Boyce. „Different things can have different effects on different populations. There is evidence that nicotine e-cigarettes can help people quit smoking, and people who do not smoke should not use e-cigarettes.“ She compares the scenario of smoking vs. e-cigarettes to the treatment of opioid use disorder. „We will not prescribe methadone to people who are not opioid-dependent,“ says Hartmann-Boyce. „But for people dependent on opioids, we know that methadone is helpful.“

The US Food and Drug Administration (FDA), which regulates e-cigarettes, has approved seven different medications that have been proven to help adults quit smoking. E-cigarettes are not among them. FDA Commissioner Dr. Robert Califf stated in an update on the FDA’s tobacco program earlier this year, „While certain e-cigarettes may help adult smokers quit smoking completely or significantly reduce their use of more harmful cigarettes, the law is meaningful to the public health. The health standard balances this potential with the known and substantial risk in terms of the attractiveness, uptake, and use of these highly addictive products among youth.“
