The facts of vaping

Does vaping cause cancer?

The current estimates are, if vaping is found to be associated with cancer, the risk is likely to be only be a tiny fraction of the risks of smoking.

Non-smokers

If you’re a non-smoker, you should not start vaping.

Although second-hand smoke is linked to lung cancer, there is no evidence yet that second-hand vapour is linked.

Smokers

Many of the cancer-causing chemicals are produced from burning tobacco in cigarettes or roll-your-own tobacco. If you’re a smoker, switching to vaping will greatly decrease your risk of cancer.

There are some toxins in vapour, but these are generally at much lower levels than what’s in cigarette smoke, or at levels that are unlikely to cause harm.

Vaping has nicotine, which does not cause cancer. However, nicotine is harmful to children and animals.
