Well I guess you have made the decision to inhale 4000 chemicals for years and light it off of a butane or lighter fluid or a match!
4-5 ingredients in PV vs 4000 chemicals in cigs! Hmmm!
Guess you could always just throw the smokes in the trash and make the smartest most healthy and informed choice or maybe check out the ingredients in the gum or the patch, or like the majority of us who couldn't quit and use the lesser of " 2 evils " LOL
The other side of this is to use the ecig to break away from about 4000 chemicals and slowly manipulate the nicotine down to 0 and then quit if it's truly a health concern!
Just for fun google chemicals in cigarettes! Wonder what is the wisest choice?
Theres many excuses we have all made to not stop smoking over the years but to make this argument about E-cigs all while probably smoking a cig while reading all this....come on give me a break! Don't mean to be so blunt and rude but this can help you quit smoking, otherwise slap on a patch but make sure and read the ingredients ! LOL
I'd agree that it's generally the lesser of two evils but you're not really making an equivalent comparison with the 4,000 chemicals versus four or five. Most of the "chemicals" that you're counting in the 4,000 number are various products of combustion and partial combustion, analogs, various trace contaminents, etc., that are not "ingredients" in the same way that you're counting the base, nicotine, flavor, etc., in juice. That's kind of the equivalent of saying that a cigarette is just tobacco, paper, and a filter.
If you did an actual analysis of juice as it's heated and "vaporized" then you'd find a much larger number of resultant products. It will start to break down and be converted into various other compounds at different temperatures, trace contaminants will be liberated, various components in different ingredients can combine, etc., etc. As in Melloh's earlier post you'll also have things like flux and solder, manufacturing oils, trace levels of solvents used in cleaning parts, various compounds in plastics, fill, foam, etc., that are volatilized at the high temps. And that doesn't even get into QA/QC-type issues, people trying to cut costs in a competitive environment, etc., and things along those lines. All of that is what you'd need to count as a valid comparison against the 4,000 number.
Like I said, I'm of the opinion that vaping is the lesser of evils but having a fairly strong biology and chemistry background I'm not naive about it. It's certainly not "just water vapor" as I see some represent it. As far as I've seen at least there's really not any good data as far as what's actually coming off of these things and there's so much variance in products and how they are used and individual circumstances that beyond generalities it would be very hard to characterize. Also, it's not so much a question of how many but rather what and in what amounts. A tiny level of one particularly bad component could be much worse than larger amounts and numbers of others. Really not trying to scare anybody, I'm on board here too, just being realistic about it. There's a lot of faith versus science at work in this 'industry' from what I've seen. All that said, given the clearly bad characteristics of the alternative, even at its worst it would be hard to equal.
