I've only been vaping for a day but so far so good so we'll see. Like I said the juice I'm using has 0 nicotine and thus far it's cut my smoking in half. Once I get some juice with a mild nicotine dosage I'll be completely chucking the cigarettes. So far it's actually a good tasting smoke. The only niggle thus far, I wish my unit gave me a slightly warmer vape
I can fill it with juice and I can pick the nicotine dosages and slowly cut the dosage until it's zero. Also, an e cigarette doesn't contain a quarter of the carcinogens and other chemical crap a cigarette does. Usually a lot of people will smoke the e cigarette and wean down to 0 nicotine or a very mild 0.3 nicotine dosage an then either stop altogether or just continue vaping off and on at the 0.3 or 0 nicotine dosage level.
I think there are slightly higher voltage units you can switch in that would give you a warmer vapor. You could check madvapes.com as they've got an enormous host of options.
