I got a starter set from VIP cigarettes. I had a voucher from groupon. I was smoking 10-15 a day, I've had it for 2 months and havent smoked for 10 days now.
It says it's not meant to be used to quit smoking, as you obviously still have the nicotine. I didn't buy it to quit, even though I wanted to. However I noticed that I smoked less and less, because it was more the habit of going outside and having a fag, that was stopping me stop smoking. With this, the habit of going outside was stopped, and then the nicotine addiction quickly got better as I was smoking less and less.
I've smoked for 9 years and have tried to quit many times, nothing has worked. So I am very surprised that this has stopped me without me even making a concerted effort.
Even if it doesn't work, at least I am not filling my lungs with tar and **** every time I smoke. So it's better either way!
Good luck.
