You tend to find that u have to try all the different types of stop smoking products to find out what works for you every ones different I like smoking the plastic pipe it helps me a lot and what I would say to anyone is to try it and if you get addicted to the plastic pipe its better to be addicted to that than a cigarette any day and at least with the plastic pipe you can reduce the amount of cartridges u use in a day at your own speed. And I buy the 42 cartridge packet for £20 and I use 3 cartridges a day so the last me 14 days so if I was smoking that would have been £140 for 14 days in my case and now it costs me £20 for 14 days now.
