E-Cigs I am about to start. Quitting is the goal

[phleshdef]

58. I've been vaping for 3 years and never experienced any irritation.

There are people with PG allergies, in which case, Vegetable Glycol based liquid can be used.

But as I said, they use this subtance in fog machines and studies were done in regard to that because bands and actors and people who have to spend a considerable amount of time standing in the "fog" are inevitably going to be breathing it in the whole time.

All the studies I've seen on the topic seem to suggest that neither PG or VG themselves are carcinogenic and neither cause any kind of damage that could lead to COPD. Of course nicotine itself, being a stimulant much like caffeine, should be taken in moderation if taken at all. But thus far, ecigs have been found to be literally thousands of times safer than the real deal cigarette. In that regard, it makes an excellent substitute for smoking if you aren't going to quit entirely. I know I'm not going to quit entirely anytime soon and I know I'm reducing my risk considerably by going with an ecig over real cigarettes. As long as I'm not overdoing the nicotine to the point that I'm bumping my heart rate up higher than normal, then I don't really see a significant downside.

I know this much, since I switched 3 years ago, my lungs feel great. I feel like I can breathe just as good as I did before I started smoking. My throat feels normal again. I don't have stains on my teeth and fingers. I don't smell bad. I'm not wasting a ton of money on cigs (e-liquid is way, way cheaper). And my cravings for nicotine are way less intense than they use to be.
