Electronic cigarettes: the new face of nicotine delivery and addiction

Electronic or “e” cigarettes are increasing in popularity worldwide as nicotine delivery devices. Chinese pharmacist Hon Lik initially developed this drug delivery device in 2003 with the goal of creating a more effective smoking cessation tool. Electronic cigarettes use batteries to heat liquid containing nicotine, which is atomized to create an inhalable aerosol. The aerosol is a mixture of propylene glycol, vegetable glycerin, nicotine, flavorings, and other toxic and non-toxic chemicals in droplet and gaseous forms.
