Absolutely helps you stop smoking, but like most things it's up to you to do it right and fight old habits.
It's the nicotine keeps you going back to the cigarettes so if you find a flavour you like more than or equal to smoking and a nicotine level equal to the old habit then you will not be missing anything that requires burning hugely expensive and cancerous dried leaves.
I smoked up to 2 packs a day and had smoked since 14 years old, I'm 52 now, I've had a brain Hemorrhage and 2 heart attacks and with huge support from my Dr and having tried every patch, gum, pill and potion known to man I never quit longer than 2 months.
9th December 2012 I took delivery of a Vamo and a couple of T3's and Vivi Nova's and since the batteries charged ready for use I have not had or craved a single cigarette and transformed my life, sounds somewhat dramatic but that's not my way, it really has improved my health and well-being beyond my expectations and being as a pack of 20 smokes costs £7 ($10) in the UK I'm sure you will appreciate the size of the financial reward.
vaping is not a one size fits all experience so you have to try a few options and discover what fits you as far as finding the right device, strength of liquid and flavour but if you stick with it there is no reason to fail, the secret I believe is research. Make the effort to discover what's out there and understand what weaknesses might exist in a particular product and roll with the punches as you will have failures with you device, you will run low on
juice.
Vaporisers do require a little bit more than pulling out of a pack and striking a match but to be honest, if a little bit of battery changing or juice dripping is too much bother then your not ready to protect your health so don't bother.... Yet.
