Electronic Cigarette: I stopped smoking 2 years ago with the electronic cigarette. Before this I was coughing ever breath and using Proventil treatments every 4 hours. Since switching I no longer cough and don't use any treatments. My lungs are completely clear, My doctor even says my lungs are completely clear. I know nicotine is not good for you but the electronic cigarette is so much better than smoking. All you are getting is prophylene glycol (used in smoke machines at concerts). None of the 4000 chemicals in cigarettes. You would not believe how many electronic cigarette users there are. I below to the Electronic Cigarette forum. Check it out.
