I started smoking at the age of 13 and was an heavy smoker between the ages of 20 and 50. A total of 37 years smoking. In 2007 I came across a personal vaporiser. An early model imitating a cigarette. I had no plans to stop smoking but needed something to get by with while working on site one or two days a week. I had tried nicotine patches and chewing gum but these had not abated the craving. I soon found that with a bit of fiddling and care with the quality of the liquid put into the device I was reaching for the so called e-cigarette and not the tobacco. The whole process from smoking 40 grams of tobacco a day to completely stopping took 5 days. I stopped smoking with out thinking about it and have had no craving to smoke a cigarette for over 6 years. My obvious concerns was whether I was replacing one bad habit with something more dangerous. So I looked at what research was available on propylene glycerine and the other ingredients of the e-liquid. Directly appropriate research was non existent but by looking back and seeing where these ingredients had been in constant use for over 50 years I felt confident that personal vaping was far lees likely to be harmful than cigarettes. Since then I kept an eye on any research that has become available, all of which have increased my confidence in personal vaporizing. Initially I started with the highest nicotine content pref filled containers. They were pretty hopeless and tried to imitate tobacco flavours. To get decent results meant buying pre-made e-liquids in bottles and dripping directly onto the atomiser. Batteries were an endless problem and they only time I have ever been tempted to buy a packet of tobacco were when the batteries kept going flat. Since that time we have had the benefit of many innovations in atomisers, battery devices and the flavours available as e-liquids. Many of the smokers I know did not have the temperament to play around with early models and found them and the cigarette lookalikes totally unsatisfactory. Since improved atomizers and flavour qualities have become available there appears to be a migration from cigarettes to personal vaporising devices among the people I know. Now I use much lower levels of nicotine in fruit or sweet flavoured juices. The improvements in the delivery systems and flavours means less reliance on nicotine content to give satisfaction. The most obvious health benefits are seen in that I no longer seem to get the wnter coughs and colds I used to suffer from. My younger daughter was telling me that both her and her sister were so much happier about me not smoking as they had become increasingly concerned about my long term health but could not foresee me ever stopping smoking. So here I am at the age of 56 and much to my surprise and everybody who knows me a non smoker for ver 6 years thanks to stumbling upon e-cigarettes, Tony
