I've seen them online mostly, I thought they were more an alternative to actually smoking rather than a quitting device? The whole point is they aren't affected by the smoking ban so you can get your nicotine fix without going outside for it. I may be wrong though! I would recommend the nicotine inhalators if you want to stop (I tried patches, Allen Carr, cold turkey & 'cutting down' before I used the inhalors). They're pricey (£22 a box I think?) but I actually went to my chemist and got them at prescription price £5, all I had to do was visit once a week and talk to the pharmacist about how I was getting on & pick up my supply of cartridges. I was on them for about 6 weeks before I didn't need them anymore. Btw, I had been smoking since I was 12 and was on more than 20 a day by the time I got round to stopping! Almost 8 years, scary stuff....!
