I started using electronic cigarettes about 18 months ago. I gradually cut down cigarettes whilst using them (had some blips where the electronic one broke and started up again) and now done smoke. I've tried various nicotine replacement therapy in the past (patches about four times, inhalator, champix, lozenges) but nothing has worked quite like my e cigarette. I've gone from 18mg to 6mg nicotine, now to get rid of the habit of this thing. Anyone else used them?
