Hon maintains a simple mechanism to create an e-cigarette. A battery powers a coil that heats a liquid containing various amounts of nicotine. It also heats propylene glycol and vegetable glycerin, which mimic tobacco smoke when heated. The flavorful “e-juice” can contain other substances, such as THC, or tetrahydrocannabinol, the psychoactive ingredient in marijuana.

E-cigarettes are mostly draw-activated, with the puffing releasing vapor. They do not produce tar and carbon monoxide. Tar and carbon monoxide are the two most noxious elements of tobacco that are associated with cancer and cardiovascular disease.

It is assumed that e-cigarettes were initially touted as less damaging than tobacco.  In 2015 public health authorities in England said That e-cigarettes were 95% less harmful than tobacco.

However, in 2019 the World Health Organization (WHO) warned that electronic smoking devices were “undoubtedly harmful and should therefore be subject to regulation”.
