The Njoy cigarettes have a new model out called Njoy Npro.  The Npro is a wonderful substitution for the real thing.  The cartridges are good for three quarters of a pack to one pack of cigarettes.  When you buy refills, the cartridges cost only $2.50 each.  This is half the price of a pack of cigarettes, and if you are trying to quit, you won’t be smoking them like you did cigarettes anyhow.  The Npro can truly help you quit if you are trying to find a way to quit while handling the cravings.   You can “smoke” an Npro and go on about your business.  These really can help you eliminate your habit.
