What are the ingredients of the electronic cigarette?

Q. Just what is in the electronic cigarette?

The principal ingredient of the electronic cigarette is propylene glycol, which is used to make stage smoke.

According to DR Murray Laugeson, who analysed the electronic cigarette for Health New Zealand:

Using micro-electronics it vaporizes, separately for each puff, very small quantities of nicotine dissolved in propylene glycol, two small well-known molecules with excellent safety profiles, – into a fine aerosol.

Other ingredients are:

  • Vegetable glycerine
  • Nicotine
  • Food grade flavourings 

Some eliquid may also include distilled water.
