Thanks for the translation, Eyedunno!

I'm not sure how much this study correlates with us vaporers who like a little nicotine in our juice. They don't allow it in Japan, although some of the samples did have it. At the very least, as the the last paragraph states, participant's cigarette consumption decreased significantly during the term of the study. I liked the part that says perhaps the decrease could be attributed to the fact the participants were required to do 150 puffs/day and probably just didn't have time to smoke an analog! :laugh:
 
@Eyedunno, I dunno how to thank you for your translation! ;)

Since the subjects went on smoking analogs during the test (however decreasing them in most cases) the results are not a shocking surprise, just a confirmation vaping it's safe.

What I'd be really glad to read is results of tests conducted on smokers, successfully quitting analogs and switching to vaping, through a couple of months or so.
This sure would be an awesome display of e-cigs healthy effects.

+1 to Eyedunno. The reduction in smoking could also indicate that much of smoking is habit related rather than nicotine dependence. That hand to mouth association can not and should not be underestimated. I sat in a bar drinking (responsibly) and playing cards for 4 hours last night. Had I still been smoking, I would have gone through close to a pack in that environment. I'm 16 months from a single drag and decided I wanted to vape a little so I took my PV with me.

I took a few puffs on my low nic PV when I got there and a few during the tournament, perhaps the equivalent to half a cigarette. For me, that hand to mouth habit has been broken.

Rothenbj says the hand to mouth habit has been broken. However, I have it from a pretty good source that his shoes didn't match and one of them was even on the wrong foot. It's possible that that PARTICULAR night of poker wasn't a fair example of how things are going each and every day. We can only hope.

Oh, and another +1 to Eyedunno!

LOL!! Probably the reason I only finished second since I took a misstep right when I could have one the whole thing. I think it's hereditary since talking to my uncle yesterday. He relayed that he once put both shoes on the wrong feet and didn't realize it till his feet started bothering him after he walked for awhile.

In poker you're sitting the vast majority of the time.

They need to bring back cigar-smoking at poker tournaments. It draws olfactory attention away from the pungencies wafting from under the table.

Cigars (good ones, at least) actually smell good. as nice as vaping is, nothing replaces those Honey flavored Backwoods! I'm sure they don't have all the nasty crap cigarettes have, either. still bad for you but so good.

From what I've read, most cigars actually produce much more "hazardous" smoke (higher levels of nicotine, carbon monoxide, and particulates are left unfiltered), but since most cigar smokers don't inhale as deeply or as often as cigarette smokers.

Because cigars are generally not inhaled into the deep lung tissue and used far less frequently than cigarette smokers who light up 20+ times a day, most studies fail to find any significant increase in morbidity for cigar or pipe smokers. That is why, along with e-cigarettes and smokeless tobacco, they remain unregulated tobacco products in the US because there is insufficient data to justify most regulations applied to cigarettes.

oh yeah I smoke both a cigar and a pipe sometimes, I never inhale at all (unless it's an accident), and when I smoke a cigar it's one in a day, when I smoke a pipe it's the same story, however I might smoke that 2 or 3 times if I'm really bored. I'm not talking about the hazard to the user, I'm talking about the smoke itself. cigarettes have a lot of nasty chemicals added to them while (good) cigars and pipe tobacco are completely left alone other than drying, flavoring, etc. I am completely convinced that second hand smoke from cigars and pipes don't hurt anybody any more than smoke from wood. Cigarette smoke on the other hand, I think it can hurt bystanders to some degree. not as much as the FDA says, but if I'm around somebody whoes smoking a cigarette when I'm sick it makes my nose hurt like something awful. I get this to some extent around cigar smoke too, but NOTHING like cigarettes. I think they put more messed up crap in those things than we even know about, I heard they even soak the tobacco in ammonia to make you absorb nicotine faster!
 
So you mean it comes from the VG instead?

When VG is heated to 280 degrees, it decomposes into acrolein. An e-cig atomizer isn't going to get that hot unless it runs dry--which would mean there wouldn't be much glycerol to decompose, and we're already dealing with very small amounts. So although it is possible that you could be exposed to some acrolein, I don't see how it could possibly be any worse than inhaling the vapors from a bag of microwave popcorn. It's something deserving of further study, but it almost cannot be a serious concern on it own, much less when compared to the amount of acrolein and other substances in actual smoke: Acrolein is a major cigarette-related lung cancer agent: Preferential binding at p53 mutational hotspots and inhibition of DNA repair

Right, Thulium! Both popcorn and the vapors coming from frying pans are the sources of much more acrolein than e-cigs. There are many, many more dangerous chemicals people should be aware of in their daily life. In my personal opinion we shouldn't be afraid of those minute amounts of acrolein.

Thanks guys! I still wish somebody who knows something about medicine and/or statistics would tell me what those numbers (+ in urine proteins, ++ {or +2 in the text of the article} in urine sugars, +++ {or +3} in urine proteins) mean.

I also found the Japanese nicotine-as-controlled-substance thing a little disheartening (especially since I would like to spend some more time there), but I at least see it having more potential for change in the near future than their other draconian drug laws (a tiny bit of ......... = YEARS IN PRISON!!!).

As for cigars, I love 'em too. But yeah, the smoke is a huge oral cancer risk compared to smokeless tobacco. Thing is, cigar smoking (for most people) tends to be less of a habitual behavior. I smoke them a few times a year, at most. I still like the smell of cigarettes too, but thanks to e-cigs, that's the only reason I ever smoke 'em (a pack a month, tops - an amazing decrease, as far as I'm concerned).
