Six things people get wrong about vaping

The study, published Wednesday in the New England Journal of Medicine, found that e-cigarettes were almost twice as effective as conventional nicotine replacement products, like patches and gum, for quitting smoking.

The researchers said that the trial provided some indication of why e-cigarettes had better results than NRT; namely, that e-cigarettes were more effective in alleviating tobacco withdrawal symptoms and may have allowed better tailoring of nicotine dose to individual needs.

"This is a well-designed and much-needed study that may have important clinical and policy implications for the use of e-cigarettes as a cessation aid", Scott Weaver, an epidemiologist at Georgia State University's School of Public Health who is not affiliated with the new research, told Gizmodo.

The study monitored almost 900 middle-age smokers that were randomly selected to use e-cigarettes or nicotine replacement products such as patches, lozenges, or gum.

E-cigarette arm abstainers experienced less severe urges to smoke at 1 and 4 weeks post-quit date. "We do think there's something unique about e-cigarettes, and they're being taken up without knowledge of the extent of their consequences". Juul's rapid popularity among teens in the USA -which has sparked fears that it could lead more young people to pick up tobacco smoking and reverse the success we've seen with lowering teen smoking rates - might explain the more reluctant attitude of doctors in the enthusiastically embrace e-cigarettes as a cessation aid.

The American Lung Association still recommends FDA approved methods of quitting smoking.

They said staff at stop-smoking services have been too reluctant to endorse e-cigarettes, because they have been cautious about the evidence behind them.

A higher proportion of those who used the devices experienced mouth and throat irritation (65 percent v 51 percent), although people using the nicotine-replacement treatments were more likely to report nausea (38 percent v 31 percent). There is no evidence that nicotine use causes health problems, but considerable evidence that many ex-smokers relapse long after they quit cigarettes.

"This is the first trial to test the efficacy of modern e-cigarettes in helping smokers quit", said lead researcher Peter Hajek, a professor at Queen Mary University of London. To objectively measure their progress, they also had their breathing levels of carbon monoxide (a common toxin in cigarette smoke that lingers in exhaled air) monitored.

Trump Says His Lawyers Assured He Is Not Target Of Mueller Probe

"All stop smoking services should welcome smokers who want to quit with the help of an e-cigarette".

Yet, the FDA's current and continued actions against the e-cigarette industry are impeding current smokers' access to e-cigarettes.

All participants received weekly one-on-one behavioural support for at least four weeks, with expired air carbon monoxide monitoring.

A second survey in 2015-2016 assessed how numerous kids had tried either vaping or smoking in the interim.

Because people had known which treatment they had received - as opposed to being "blinded" as they are in most randomised controlled trials - it was possible participants may have perceived nicotine replacements as an inferior option and put less effort into quitting, the authors said.

"What is in an e-cig?"

Juul Labs Inc., the vaping market leader whose devices are wildly popular with teens, says on its website that "our development and manufacturing process does not add diacetyl and acetylproprionyl (or 2,3-pentanedione) as flavor ingredients".

The Harvard study published in Scientific Reports determined that two chemicals commonly used to flavor e-cigarettes may be harming the cilia, the antennae-like protrusions that line human airways to help keep them clean.

Myth #3: E-cigarettes are just as unsafe as combustibles because they contain nicotine.
