Why smoke at all. A habit i can never understand.
I can understand older people with problems trying to relieve the stress, but
there are so much better ways to do that.

That article was discredited as soon as it came out.

When you use a vaporizer for a cold........do you use 500 degree steam?

I'll take second hand smoke to mob rule any day.

It is not known exactly where formaldehyde contained in hemiacetals gets deposited in the body or whether it is similarly toxic, said James Pankow, one of the study's authors.

"There has never been a cancer study with hemiacetals," Pankow said in an interview.

Absent such a study, the authors estimated the formaldehyde-related cancer risk associated with e-cigarettes by extrapolating from data on formaldehyde in cigarettes.

They concluded that the life-time risk of developing formaldehyde-related cancer at roughly 1 in 200 for high-voltage e-cigarettes versus 1 in 1,000 for cigarettes - at least five times higher. They found no increased risk for people vaping at a low voltage.

Dr. Neal Benowitz, a nicotine expert at the University of California, San Francisco, said the study could prove useful to the U.S. Food and Drug Administration as it prepares to regulate e-cigarettes, potentially including limits on formaldehyde.

But he questioned the legitimacy of comparing the effect of formaldehyde delivered in a cigarette to that delivered via hemiacetal, in droplet form, in an e-cigarette.

Pankow conceded that the study could have contained more context about overall relative risk, but said the authors "just wanted to get it out."

They submitted it to the NEJM in the form of a letter, which a spokeswoman for the journal said was peer-reviewed. Pankow said letters tend to be less detailed than other studies.

David Abrams, executive director of the Schroeder Institute for Tobacco Research and Policy Studies at the anti-tobacco group Legacy, said he was concerned the study would be taken out of context "in the worst possible way."
