Reto Auer, MD, MAS Institute of Primary Health Care (BIHAM), University of Bern, Bern, Department of Ambulatory Care and Community Medicine University of Lausanne, Lausanne, Switzerland : What is the background for this study?Response: When the tobacco industry began to promote new “heat-not-burn” (HNB) tobacco cigarettes as a “safer” alternative to traditional cigarettes, we wanted to find out if their claims were true.Philip Morris International (PMI) created an HBN called IQOS® (I-Quit-Ordinary-Smoking).IQOS® uses tobacco sticks soaked in propylene glycol, which are inserted into a holder and heated to a maximum of 350°C.PMI claims that because its HNBs don’t combust, they emit far fewer harmful chemicals than conventional cigarettes.We decided to test their claims.: What are the main findings?Response: We designed and tested a smoking device and then used it to capture heat-not-burn emissions.Volatile organic compounds (VOCs), PAHs, and carbon monoxide (CO) were definitely present in IQOS smoke.

VOC and PAHs are the family of substances which cause heart attacks and cancers, amongst others in cigarette smokers.: What should readers take away from your report?Response: There is smoke without fire.IQOS® releases smoke, probably because tobacco degrades from the heat even when oxygen is not present.This process, called pyrolysis of tobacco, releases most of the harmful chemicals in smoke.Heating tobacco or wood to 330°C alters its composition and releases smoke, despite the absence of oxygen, creating char.IQOS® is probably charring tobacco instead of partly burning it like conventional cigarettes do.Pyrolysis occurs during both burning and charring, so the smoke released by both IQOS® and conventional cigarettes is not as different as PMI might wish the public to believe.The same chemicals are present, though in different amounts.: Is there anything else you would like to add?Response: We need more independent studies to provide accurate information to the public and stakeholders.

We cannot trust industry to conduct and interpret studies that evaluate the safety of their own products because their financial stake in a positive outcome is too high.As far as we know, we are the only independent team to compare heat-not-burn cigarettes with conventional cigarettes.da vinci vaporizer europeIndependent studies are much more reliable than industry-conducted or sponsored tests because independent researchers have no financial conflict of interest.g pro vaporizer opinionesAuer R, Concha-Lozano N, Jacot-Sadowski I, Cornuz J, Berthet A.

Andre Calantzopoulos, PMI's chief executive, says he would like to work with governments towards the "phase-out" of conventional cigarettes.In his first UK broadcast interview, he has told the Today programme that the company knows its products harm their consumers, and that the only correct response is to "to find and commercialise" ones that are less harmful.iqos vs electronic cigarette"That is clearly our objective," he said.It is not the first time cigarette makers have experimented with heating rather than burning tobacco to do less less damage to consumers.iqos leather caseIn the 1980s, Reynolds, the big American tobacco company, produced the Premier, which heated tobacco but which still involved some combustion.It lasted a year, with customers complaining of a complicated lighting procedure and a charcoal aftertaste.PMI's solution is much more Silicon Valley.

The Iqos is a £45 battery pack that looks like a small, dumpy mobile phone.It charges a slim cigarette holder.You buy packets of tobacco sticks - a packet of 20 will cost £8 - that look like someone has taken a pair of scissors to normal cigarettes and chopped them in half.The stick goes in the holder, and you puff away.There is much less smoke than a conventional cigarette, and, users say, the smell does not stick to your clothes.Other cigarette companies are not far off producing rival versions.E-cigarettes, which use an electronic system to deliver nicotine via a water vapour, are a different alternative.Mr Calantzopoulos, however, points out their basic weakness.They are not very effective in converting traditional smokers.The conversion rate to e-cigs of smokers is just 20%.Trials in Japan have shown that 70% of smokers stay with the new substitute once they have tried it.Shareholders, Mr Calantzopoulos says, are enthusiastic about the new product.He will need their backing, as traditional tobacco has proved an enormous money spinner.
