Behind the smoke screen

Smoke grenade Smoke grenade These are canister-type grenades used as a ground-to-ground or ground-to-air signaling device. The body consists of a steel sheet metal cylinder with a few emission holes on top and on the bottom to allow smoke release when the smoke composition inside the grenade is ignited.

Tom Whalen Advertisement Television advertisements for cigarettes have been banned in the U. Electronic cigarettes, or e-cigs, as they are known, soaked up the spotlight in recent Super Bowl commercials, on late-night talk shows and in a comedy sketch during the Golden Globe Awards.

Indeed, a recent survey shows that nearly 60 percent of Americans are now familiar with the sleek, smokeless devices. The concept behind e-cigs is clever: E-cigs use a small, heated coil to vaporize a nicotine-laced solution into an aerosol mist.

By inhaling the mist, users enjoy the same satisfaction they would get from an ordinary cigarette but do not expose themselves to tobacco, which turns into cancer-causing tar when it is burned.

Such products free smokers from huddling in the cold or rain and, in many places, from ordinances that forbid smoking in public places. But are e-cigs truly safe? No one knows for sure. Yet there is no question that the nicotine they contain is addictive—which is one reason many public health experts have grown alarmed by their rapidly increasing popularity.

Food and Drug Administration and the European Union are grappling with these issues as they decide how to regulate the products. Unfortunately, they must act before all the facts are available. Unfettered access could leave people vulnerable to unknown health hazards, but there is also the chance that greater restrictions might hurt folks who are trying to forgo conventional—and more dangerous—tobacco products.

First Puffs The current iteration of e-cigarettes was invented and popularized by Chinese pharmacist Hon Lik in and entered the U. A federal appeals court ruled in December that the agency lacked authority over e-cigs because they offer only the recreational benefits of a regular cigarette.

That legal decision allowed sales of e-cigarettes to proceed but left many questions about their safety unaddressed. In lieu of carcinogenic tobacco, e-cigarettes typically contain three main ingredients: The primary established danger of nicotine is that the stimulant is highly addictive, although emerging science also links it to an impaired immune system.

Yet more needs to be understood before e-cigarettes can be a given a clean bill of health.

Propylene glycol, for example, is usually eaten in cupcakes, soft drinks and salad dressings or slathered onto the body in soaps, shampoos and antiperspirants —not breathed into the lungs.

Many things that can be safely eaten—such as flour—can damage the lungs when inhaled. No one knows whether propylene glycol falls into that category. An assessment from the agency, issued inreferences only a couple of studies that cover inhalation exposures—all with laboratory animals rather than people.

Beyond the three main ingredients, some researchers worry about by-products from heating electronic cigarettes and the solution inside them. Various studies suggest the vapors from e-cigarettes contain several cancer-causing substances, as well as incredibly tiny particles of tin, chromium, nickel and other heavy metals, which, in large enough concentrations, can damage the lungs.

These particles likely fleck off the solder joints or metal coil in the devices when heated. Because they are so small, the tiniest bits of metal, known as nanoparticles, can travel deep into the lungs. There they could exacerbate asthma, bronchitis—an inflammation of the tubes that carry air to and from the lungs—and emphysema—a disease in which the lungs' many air sacs are destroyed, leaving patients short of breath.The signs are mounting that President Lourenço is hiding his authoritarian claws behind the façade of his anti-corruption rhetoric.

Little else is happening in the country besides smoke screens and the maintenance of the status quo. Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.

Here in BADvertising Country we counter the seduction of dishonest tobacco advertising by doctoring-up tobacco ads to make them honest.

By juxtaposing funny, gross, and disgusting images on top of deceitful ads, we jolt people into realizing how tobacco ads are concealing the truth about smoking.
