We'd like our readers to start paying for Daily Maverick

More specifically, we'd like those who can afford to pay to start paying. What it comes down to is whether or not you value Daily Maverick. Think of us in terms of your daily cappuccino from your favourite coffee shop. It costs around R35. That’s R1,050 per month on frothy milk. Don’t get us wrong, we’re almost exclusively fuelled by coffee. BUT maybe R200 of that R1,050 could go to the journalism that’s fighting for the country?

We don’t dictate how much we’d like our readers to contribute. After all, how much you value our work is subjective (and frankly, every amount helps). At R200, you get it back in Uber Eats and ride vouchers every month, but that’s just a suggestion. A little less than a week’s worth of cappuccinos.

We can't survive on hope and our own determination. Our country is going to be considerably worse off if we don’t have a strong, sustainable news media. If you’re rejigging your budgets, and it comes to choosing between frothy milk and Daily Maverick, we hope you might reconsider that cappuccino.

We need your help. And we’re not ashamed to ask for it.

Vape Products Contain Potentially Harmful Chemicals, Researchers Say

(Bloomberg) --Vaping exposes users to around 2,000 chemicals, including potentially harmful industrial compounds, according to a study of four popular brands by researchers at Johns Hopkins University.

Most of the chemicals found were unidentified, but of those that were, six were cause for concern, according to the study published in Chemical Research in Toxicology, a peer-reviewed journal. Researchers found condensed hydrocarbon-like compounds that are typically associated with traditional combustion products like cigarettes, despite the fact that vaping is often marketed as safer than those products. The study also found caffeine in some, which isn’t disclosed on labels.

E-liquids — a mixture of water, nicotine and other ingredients that are found in vaping products — and aerosols were studied for products sold by Juul Labs, British American Tobacco, ITG Brands and Mi-One Brands. The companies didn’t immediately return messages seeking comment.

“People just need to know that they’re inhaling a very complex mixture of chemicals when they vape. And for a lot of these compounds, we have no idea what they actually are,” Carsten Prasse, an assistant professor of environmental health and engineering at Johns Hopkins and a senior author of the study, said in a statement.

Cigarette makers like BAT and Altria Group Inc., which owns a stake in Juul, are striving to convert smokers to nicotine alternatives such as e-cigarettes that they’ve framed as having reduced risk. Regulators have yet to fully agree: The U.S. Food and Drug Administration has authorized some products for sale under the reduced-risk logic, but the agency is still reviewing thousands of applications by e-cigarette makers to keep current products on the market. To do so, companies need to prove that their products’ benefit for adult smokers outweighs the public-health threat posed by youth use.

The Johns Hopkins study, which the FDA is reviewing, looked at only tobacco-flavored liquids. Recent decisions from the FDA have determined that thousands of flavored products will need to be removed from the market.

Caffeine, Flame Retardant
Researchers found caffeine in BAT’s Vuse and Mi-One’s Mi-Salt vaping products. The FDA allows caffeine to be added to beverages and food as long as it’s listed in the ingredients panel.

Juul’s devices, meanwhile, contained a chemical commonly used as a flame retardant for polymers, which the study speculated might be a contaminant from the device itself. Condensed hydrocarbon-like compounds increased in all of the products due to vaping except in ITG’s Blu.

Hazardous chemicals highlighted in the study include isophorone, detected in Mi-Salt and Vuse products, which can cause effects ranging from nose and throat irritation to fatigue and depression, according to the Environmental Protection Agency. Vanillin, a synthetic form of vanilla flavoring that has been reported to cause allergic reactions and other ailments, was detected in Mi-Salt, Vuse and Blu.

“Existing research that compared e-cigarettes with normal cigarettes found that cigarette contaminants are much lower in e-cigarettes,” Prasse said. “The problem is that e-cigarette aerosols contain other completely uncharacterized chemicals that might have health risks that we don’t yet know about.”

Michael Bloomberg, founder and majority owner of Bloomberg News parent Bloomberg LP, has been a longtime champion of tobacco-control efforts. He also is a major donor of Johns Hopkins University, where he received a degree.
