Hi PD
I'm not all that keen on the e-cig. The one I tried is the Matchless, which seems pretty well reviewed. I have a few issues:
1. the ethylene glycol content. From my brief reading of the subject, the long term effects of inhaling this are unknown. Ever since I read that this is one of the ingredients, I have had a faint smell/taste of antifreeze or similar when using the e-cig. I appreciate that the possible harmful effect of the e-cig is much much less than that of cigarettes but nevertheless I am not sure that inhaling this stuff is the way I want to go.
2. Using the e-cig makes me feel just very very mildly ill, with a slight sense of some physiological effect that is different from the effect of smoking cigarettes. I don't really like that.
3. I am not convinced that it is delivering an effective dose of nicotine. I noted some research that showed that the nicotine levels in users' blood was often negligible, so the value of the e-cig lies elsewhere (the act of inhaling, "throat hit", etc).
4. Using the e-cig has made me realise that I do not actually have a strong need to inhale smoke, or to be doing something with my hands, so those benefits of the e-cig don't apply to me.
Overall, I don't think this is for me. I need to stop them entirely.
