There used to be a website called http://www.TVECA.com however lately I've been having trouble finding it. However, as a vap-er since the beginning, I can tell you it is at least 10,000 times healthier than analogs. There are over 10,000 "known" chemicals (and an undetermined amount of undiscovered hazards) found in traditional tobacco cigarette smoke. Compare to the four (yes 4) ingredients in e-cigs. The most controversial being the propylene glycol, or "PG" which is used in other food, beverage, and cosmetics which some liken to "anti-freeze" but is safe for consumption.. Today almost all e juice is comprised of a mixture of PG and VG (vegetable glycerin,) made strictly from vegetables. PG produces more vapor while VG is sweeter producing more flavor. Most e juices fall somewhere between 50/50, and the highest I've seen.. 80/20 ratio. Aside from that one (or combination of the two,) the only other ingredients should be; water, nicotine (ranging from zero up to as high as 36 mg, and the flavoring. There are over 30,000+ flavor combinations and counting. Anyway that's my two cents for now hope that helps.
