A systematic review published in August identifies a range of health consequences for children and young people who vape. The extent of likely harmful effects is wider than anticipated and increasingly evident in hospital practice. The authors call for governments to legislate and enforce laws effectively.

Key Facts

A systematic review published in August identified a range of health consequences for children and young people who vape.
E-cigarettes deliver nicotine at levels comparable with or higher than typical tobacco cigarettes.
Nicotine is known from decades of studies of smokers to impair fetal and adolescent brain development.
E-cigarettes have been shown to contain harmful substances, including heavy metals such as lead, toxic carbonyls, nanoparticles, and unregulated substances such as synthetic cannabinoids.
Even low-level, intermittent use can quickly lead to symptoms of nicotine dependence, with some young users reporting cravings and withdrawal from occasional exposure.

Health Risks for Youth

The systematic review published in August identified a range of health consequences for children and young people who vape. Nicotine is a highly addictive substance that is known, from decades of studies of smokers, to impair fetal and adolescent brain development. Even low-level, intermittent use can quickly lead to symptoms of nicotine dependence. Some young users report symptoms of dependence, including cravings and withdrawal from occasional exposure.

Chemical Composition and Concerns

E-cigarettes have been shown to contain harmful substances, including heavy metals such as lead, toxic carbonyls, nanoparticles, and unregulated substances such as synthetic cannabinoids. The longer-term health concerns are yet to emerge, but these substances are known to be pro-inflammatory, immunosuppressive, carcinogenic and highly addictive in their own right. The continued increase in vape use since their development has coincided with the rediscovery of nicotine salts.
