Why is Propylene Glycol Used in Electronic Cigarettes?

One of the aspects of electronic cigarettes that make them attractive for prior users of traditional tobacco is the similar look and feel that e-cigs have to regular smokes. A problem arises, however, when just vaporizing nicotine, water, and the flavoring ingredients– there is no smoke produced. As a result, propylene glycol (or PG for short) is added to the e liquid mixture in order to produce an colorless vapor when smoking an e-cig. This helps better mimic the action of smoking without producing the dangerous second hand smoke produced by regular tobacco cigarettes.
