E-cig users develop some of the same cancer-related molecular changes as cigarette smokers

Source: EurekAlert! Date: February 14, 2019 If you think vaping is benign, think again. A small USC study shows that e-cig users develop some of the same cancer-related molecular changes in oral tissue as cigarette smokers, adding to the growing concern that e-cigs aren't a harmless alternative to smoking. The research, published this week in the International Journal of Molecular Sciences, comes amid a mushrooming e-cig market and mounting public health worries. On a positive note, recent research found vaping is almost twice as effective as other nicotine replacement therapies in helping smokers quit. But among adolescents, vaping now surpasses smoking, and there's evidence that e-cig use leads to nicotine addiction and future smoking in teens. "The existing data show that e-cig vapor is not merely 'water vapor' as some people believe," said Ahmad Besaratinia, an associate professor at Keck School of Medicine of USC and the study's senior author. "Although the concentrations of most carcinogenic compounds in e-cig products are much lower than those in cigarette smoke, there is no safe level of exposure to carcinogens." Besaratinia emphasized that the molecular changes seen in the study aren't cancer, or even pre-cancer, but rather an early warning of a process that could potentially lead to cancer if unchecked. The researchers looked at gene expression in oral cells collected from 42 e-cig users, 24 cigarette smokers and 27 people who didn't smoke or vape. Gene expression is the process by which instructions in our DNA are converted into a functional product, [...]

E-Cigarettes Are in Vogue and at a Crossroads

By LIZ ALDERMANPublished: June 12, 2013Source: NY Times PARIS — On a recent day in the shadow of the Arc de Triomphe, a line of 20 people spilled onto the sidewalk of a trendy new boutique, eager to get a taste of its latest gourmet offerings. Olivia Foiret, the manager of ClopiNette, demonstrates filling an e-cigarette for a client. A sign in the window promoted piña colada as the store’s flavor of the month. A woman wearing a Chanel jacket said she wanted to try peach. But this was no temple of gastronomy. It was one of scores of electronic cigarette shops that have been springing up by the week in Paris as well as in numerous cities across Europe and the United States. Inside the ClopiNette boutique, shoppers can choose from among more than 60 flavors of nicotine liquid — including Marlboro and Lucky Strike flavors — all in varying strengths and arranged in color-coded rows. (ClopiNette is a play on “clope,” French slang for a cigarette.) “It’s like visiting a Nespresso store,” said Anne Stephan, a lawyer specializing in health issues at a nearby law firm. What’s driving her into the store is a desire shared by many: they want to give up smoking tobacco but don’t want to kick the smoking habit. After smoking 20 cigarettes daily for 25 years and failing to quit, Ms. Stephan said she had cut down to one a day in the three months since she began puffing on a so-called e-cig. Using [...]

Chinese e-cigs gain ground amid safety concerns

Source: apnews.myway.com Author: Audra Ang With its slim white body and glowing amber tip, it can easily pass as a regular cigarette. It even emits what look like curlicues of white smoke. The Ruyan V8, which produces a nicotine-infused mist absorbed directly into the lungs, is just one of a rapidly growing array of electronic cigarettes attracting attention in China, the U.S. and elsewhere - and the scrutiny of world health officials. Marketed as a healthier alternative to smoking and a potential way to kick the habit, the smokeless smokes have been distributed in swag bags at the British film awards and hawked at an international trade show. Because no burning is involved, makers say there's no hazardous cocktail of cancer-causing chemicals and gases like those produced by a regular cigarette. There's no secondhand smoke, so they can be used in places where cigarettes are banned, the makers say. Health authorities are questioning those claims. The World Health Organization issued a statement in September warning there was no evidence to back up contentions that e-cigarettes are a safe substitute for smoking or a way to help smokers quit. It also said companies should stop marketing them that way, especially since the product may undermine smoking prevention efforts because they look like the real thing and may lure nonsmokers, including children. "There is not sufficient evidence that (they) are safe products for human consumption," Timothy O'Leary, a communications officer at the WHO's Tobacco Free Initiative in Geneva, said this week. The [...]
