I am writting this in response to not only my health, rather all those
 tobacco smokers wishing to quit smoking. Although the electronic
 cigarette is just another alternative to help smokers kick the habit
 by reducing the nicotine intake from a High Level to a Medium, Low
 and finally zero nicotine level after approximately 4 to 6 months. The
 vapor from the e-cigs are not harmful to breath. These are truely a
 medical and scientific breakthrough for tobacco smokers healthwise.
 My only suggestion is that pure vegetable based propylene glycol  be used in the electronic cigarette instead of the present type being used

 today. They are most assuredly 99.9% safer for the user healthwise
 than traditional tobacco burning cigarettes. Why are they still legal to
 smoke?  The FDA nor the US has not blocked the sale of the number 2
 killer in the world? Alcohol being number 1 in my opinion. Please allow
 smokers the freedom and right to choose the electronic cigarette with-
 -out the FDA blocking the sale of a truely medical breakthrough here in
  this great country of ours. The good ole USA!  Wendel A. Midkiff
