What is the available evidence to date on the
health risks of using e-cigarettes?
• While using an e-cigarette may not be 100% safe, most of the
chemicals that cause smoking-related diseases are absent from e-
cigarette vapour, and the chemicals that are present are found at
levels that pose little harm to health.
• The long-term health effects of e-cigarette use are unknown but,
compared with cigarettes, e-cigarettes are likely to be much less, if
at all, harmful to users or bystanders.
• Evidence suggests the possibility that some harm from long-term e-
cigarette use cannot be ruled out.
• Sustained exposure to low levels of toxins in e-cigarette vapour over
many years may pose some risks to health, particularly in relation
COPD and lung cancer. But the magnitude of these risks is likely to
be very small in absolute terms, and substantially smaller than the
risks arising from sustained tobacco smoking.
