While vapes have a role as smoking cessation aids, public health concerns include marketing and the prevalence of rogue products

Vapes and e-cigarettes are electronic devices enabling nicotine to be inhaled as a vapour instead of as smoke. They are less harmful than cigarettes because they do not contain carbon monoxide, tar and other toxic chemicals such as arsenic and benzene. A solution in the vape, known as an e-liquid, contains varying strengths of nicotine and sometimes flavourings, allowing for a tapered nicotine withdrawal.
