Jan 19, 20211. Introduction to electronic cigarettes. Electronic cigarettes (ECIGs), also known as smokeless cigarettes, e-hookahs, vape pens and vapes, are electronic devices that heat and vaporize a solution that usually contains a mixture of glycerol, propylene glycol, water, flavors and various nicotine concentrations ().The first electronic cigarette patents date back to 1965().
