Americans are confused about electronic cigarettes.A recent poll showed that the public was about evenly split between those who thought that electronic cigarettes, or e-cigarettes, were less harmful than conventional cigarettes, and those who believed that e-cigarettes were as bad as or worse than regular cigarettes.Unfortunately, there is no long-term safety data about e-cigarettes.What information we do have suggests that e-cigarettes have a complex mix of potential harms and benefits.First, the good news: e-cigarettes are almost certainly less lethal than conventional cigarettes.Cigarette smoking is a uniquely dangerous addiction.In fact, cigarettes might be the only consumer product that kills when used as directed.Cigarettes are the number one cause of preventable death in the United States, killing 480,000 people every year.That’s more deaths than HIV, heroin, methamphetamine, cocaine, alcohol, motor vehicle accidents, and firearms combined.Smoking increases the risk of stroke, heart attack, COPD, asthma, diabetes, and most cancers.

The free radicals in cigarette smoke physically age the human body.On average, smoking reduces your life span by at least 10 years.Tobacco could not possibly be approved for sale in the United States today if it was a new product coming on the market.A burning cigarette gives off noxious gases, such as carbon monoxide and hydrogen cyanide.Cigarette smoke also contains an ultrafine suspension of gummy residue, known as tar.Most of the carcinogens in cigarette smoke are found in the tar.The major benefit of e-cigarettes, compared to regular cigarettes, is that they do not produce the tar or the toxic gases found in cigarette smoke.An e-cigarette contains a cartridge of fluid, popularly known as e-liquid.E-liquid is made up of nicotine and flavorings dissolved in propylene glycol and glycerol.The e-liquid is superheated by a battery-powered vaporizer, converting it into a mist which is inhaled, or “vaped.” Studies about e-cigarettes and smoking behavior show conflicting results.E-cigarettes were mildly helpful in kicking the habit in one clinical trial.

In other studies, e-cigarette use did not increase quit rates, or was even associated with a higher risk of continuing to smoke.A recent review concluded that real-world use of e-cigarettes is associated with lower quit rates.Now the bad news.Nicotine in e-cigarettes may have several negative health effects.Chronic nicotine exposure may lead to insulin resistance and type 2 diabetes, although this risk may be offset by the well-known appetite suppressant effects of nicotine.e zigarette ovg münsterInhaled nicotine increases heart rate and blood pressure.e cigarette missoula mtNicotine is highly addictive in its own right, and it may lead to changes in the brain that increase the risk of addiction to other drugs, especially in young people.macau e cigarette

Nicotine may also impair prefrontal brain development in adolescents, leading to attention deficit disorder and poor impulse control.These potential harms of nicotine are particularly worrisome in view of soaring rates of e-cigarette use in U.S.The nicotine in e-liquid may also be a household hazard.Many e-liquids have candy and fruit flavoring and packaging that makes them attractive to children.Cases of nicotine poisoning from e-liquid have skyrocketed, with accidental ingestions of e-liquid by kids rising by 1,500% in the past three years.e cigarette segamatFlavored e-cigarettes may pose another health threat.e cigarette puerto vallartaThey often contain a chemical compound called diacetyl, which is associated with a rare lung disease called bronchiolitis obliterans that causes permanent damage to the bronchioles (the tiniest airways in the lungs).e cigarette penny stocks

Propylene glycol and glycerol, the major components of e-liquids, are not thought to be dangerous on their own.However, they may decompose when heated by the vaporizer, and be transformed into toxic compounds such as formaldehyde.This is more common with newer vaporizers that use high wattages.Related Information: Harvard Men’s Health WatchThe e-cigarette industry got some good news this week: A survey of almost 6,000 smokers in Britain trying to quit found that those who used electronic cigarettes were more likely to stop using smoking tobacco than those who used over-the-counter quitting aids or had no help at all.The study, accepted by the journal Addiction and published online Tuesday, comes as U.S.regulators weigh new rules for nicotine vaporizers.The e-cig industry and public health officials are battling over whether the devices should be treated as less-harmful cigarettes that help smokers give up tobacco or as a gateway that will lead adolescents to a deadly habit.Investigators from a cancer research center at the University College London conducted the study, which was partially funded with government and drug industry grants.

None of the authors reported financial ties to e-cigarette companies, which adds to the report’s credibility.The latest analysis drew on surveys of British households from 2009 to 2014 and counted smokers who had tried to quit within the past 12 months.A majority used no help, about one-third tried over-the-counter aids, such as nicotine patches or gums, and 8 percent used e-cigarettes.The study excluded people who used prescription medicines or counseling to quit smoking, as well as those who used both e-cigs and nicotine replacement.E-cig users were more likely to have stopped smoking tobacco by the time of the survey than either of the other groups.While surely welcome news for fans of vaping, these survey results are not the kind of evidence that proves e-cigarettes are effective quitting aids and would let the industry market them as such.For that, regulators want to see rigorous, randomized control trials that compare e-cigs with placebo treatments.E-cigarettes are also an evolving technology, with varying formulas and designs that may have different effects on users.

And the research doesn’t address whether smokers relapse more when using e-cigs than other quitting methods.Scientists also haven’t established what risks e-cigarettes might pose to long-term users.It’s impossible to know how these products will affect people over decades, because the products are less than 10 years old.Other risks associated with e-cig use: They occasionally explode, and children or pets may accidentally consume the poisonous liquid if it’s left unsecured.While vaping is widely believed to be safer than inhaling tobacco smoke, it’s “not safer than just breathing clean air,” as Dr. Richard Hurt, former director of the Mayo Clinic’s Nicotine Dependence Center, said in a recent interview.Other research in the U.S.suggests that smokers’ perception that e-cigarettes are less harmful is declining.Still, many people report anecdotally that e-cigs help them trade a habit known to be deadly for one presumed to be less dangerous, even when other approaches failed.
