The US Food and Drug Administration pressed forward with its investigation of e-cigarette companies Friday, sending letters to 21 companies in an effort to uncover whether they are marketing products illegally and outside the agency's compliance policy.This latest phase of the investigation addresses more than 40 e-cigarette products and is part of the agency's ongoing efforts to combat e-cigarette use among youth. It also comes less than two weeks after the agency conducted a surprise inspection of e-cigarette maker Juul's corporate headquarters in San Francisco, seizing thousand of documents, many of which relate to its sales and marketing practices."Companies are on notice," FDA Commissioner Dr. Scott Gottlieb said in a statement Friday. "The FDA will not allow the proliferation of e-cigarettes or other tobacco products potentially being marketed illegally and outside of the agency's compliance policy, and we will take swift action when companies are skirting the law."In September, Gottlieb called the increasing teen use of e-cigarettes "an epidemic," adding that teen nicotine use is dangerous to young people's health and brains.Federal law prohibits the sale of e-cigarettes to people under the age of 18, but more than 2 million middle and high school students were current users of e-cigarettes in 2017, according to the FDA. The US Centers for Disease Control and Prevention says it's the most common nicotine product used by middle and high schoolers.Also last month, the FDA requested that five major e-cigarette manufacturers, including Juul, explain how they plan to combat the use of their products by minors. The agency said it was looking into steps to eliminate the sale of flavored products and unveiled a public education campaignabout e-cigarettes.The FDA said it's considering civil and criminal avenues to enforce these regulations, including fines, seizures and injunctions, according to Friday's announcement.CNN reached out to some of the companies that received letters for comment but did not immediately receive a response."We're going to address issues related to the access kids have to e-cigarettes, as well as the youth appeal of these products," Gottlieb said Friday. "We know flavors are one of the principal drivers of the youth appeal of e-cigarettes and we're looking carefully at this."No reasonable person wants to see these products reaching epidemic use among kids," he said. 2500

The U.S. continues to lead the world in deaths linked to COVID-19 with more than 222,000 — and some experts believe that figure is much higher. But according to a new study, at least 130,000 of those deaths could have been avoided.According to a study by the National Center for Disaster Preparedness at Columbia University, the U.S. could have avoided between 130,000 and 210,000 COVID-19 deaths had the country adopted mitigation policies similar to those used by other "high-income nations."It's clear that the U.S. has disproportionately felt the affects of the pandemic — though it has just 4% of the world's population, it accounts for 20% of COVID-19 cases worldwide. The U.S. death toll stands in stark contrast to countries with similar resources, like South Korea, Japan, Australia, Germany, Canada, and France.To calculate the U.S.'s "avoidable deaths," the study applied the death rates of those countries to the U.S.'s population. Researchers then subtracted that figure from the U.S.'s current death count.By that calculation, researchers concluded that 130,000 lives could have been saved had the U.S. adopted policies similar to that of Canada's, and that as many as 215,000 lives could have been saved had the country adopted policies similar to South Korea.In explaining why U.S. deaths are disproportionately high, the Columbia researchers cited four key mistakes:Insufficient testing capacity: Researchers cited issues the U.S. had early on in the pandemic in developing and acquiring tests, while countries like South Korea were prepared almost immediately to test for the virus on a widespread scale.Delayed response: A previous Columbia University study determined that instituting national social distancing measures just one or two weeks earlier would have saved 36,000 of lives.Lack of a national mask mandate: Top health officials recommended against masks early on in the pandemic, fearing that doing so would lead to a shortage. Even today, masks have become politicized in some circles despite evidence showing that wearing one reduces the spread of droplets that can carry the virus.Failure from federal leadership: The Columbia study cited the Trump administration's "hostility to much of the critical guidance and recommendations put forth by its own health agencies," specifically citing the president's attempts to "downplay" the virus.Read more about the Columbia University study here. 2430

The U.S. Food and Drug Administration has issued a warning about several hand sanitizer products that have been found to contain wood alcohol, which can potentially be deadly to ingest or on the skin.The FDA said the products from EskBiochem SA de CV in Mexico contain methanol, also known as wood alcohol, which can be deadly when absorbed through the skin or ingested. Substantial methanol exposure can result in nausea, vomiting, headache, blurred vision, permanent blindness, seizures, coma, permanent damage to the nervous system or death."Methanol is not an acceptable ingredient for hand sanitizers and should not be used due to its toxic effects," the FDA wrote in their statement.While anyone who puts methanol on their hands is at risk, officials say young children who accidentally ingest these products and adolescents and adults who drink these products as an alcohol (ethanol) substitute, are most at risk for methanol poisoning.On June 17, the FDA contacted Eskbiochem to recommend they remove its hand sanitizer products from the market. However, to date, the company has not taken action to remove the products from the market and the FDA is urging people to stop using them, and dispose of them properly. 1231

The Trump Administration wants to change the definition of a showerhead to let more water flow, addressing a pet peeve of the president who complains he isn’t getting wet enough.Publicly talking about the need to keep his hair “perfect,” President Donald Trump has made increasing water flow and dialing back long held appliance conservation standards — from light bulbs to toilets to dishwashers — a personal issue.But consumer and conservation groups said the Department of Energy’s proposed loosening of a 28-year-old energy law that includes appliance standards is silly, unnecessary and wasteful, especially as the West bakes through a historic two-decade-long megadrought.Since 1992, federal law has dictated that new showerheads shouldn’t pour more than 2.5 gallons of water per minute (9.5 liters). As newer shower fixtures came out with multiple nozzles, the Obama administration defined the showerhead restrictions to apply to what comes out in total. So if there are four nozzles, no more than 2.5 gallons total should come out between all four.The new proposal Wednesday would allow each nozzle to spray as much as 2.5 gallons, not just the overall showerhead.With four or five or more nozzles, “you could have 10, 15 gallons per minute powering out of the showerhead, literally probably washing you out of the bathroom,” said Andrew deLaski, executive director of the energy conservation group Appliance Standards Awareness Project.On the White House South Lawn in July, Trump made the issue personal:“So showerheads — you take a shower, the water doesn’t come out. You want to wash your hands, the water doesn’t come out. So what do you do? You just stand there longer or you take a shower longer? Because my hair — I don’t know about you, but it has to be perfect. Perfect.”DeLaski and officials at Consumer Reports said there’s been no public outcry or need for change. The Department of Energy’s own database of 12,499 showerheads showed 74% of them use two gallons or less water per minute, which is 20% less than the federal standard.“Frankly it’s silly,” deLaski said. “The country faces serious problems. We’ve got a pandemic, serious long-term drought throughout much of the West. We’ve got global climate change. Showerheads aren’t one of our problems.”Energy Department spokeswoman Shaylyn Hynes said the 2013 Obama definition of showerhead clashes with what Congress intended and the standards of the American Society of Mechanical Engineers.If the rule is adopted, Hynes said it would be “allowing Americans — not Washington bureaucrats — to choose what kind of showerheads they have in their homes.”Officials at the industry group Plumbing Manufacturers International did not respond to a request for comment.Appliance and plumbing energy and water conservation standards save consumers about 0 a year on energy bills, deLaski said.If people are having trouble getting water flowing in their shower, they should check their home’s water pressure and can replace a faulty showerhead for not much money, deLaski said.A 2016 test of showerheads by Consumer Reports found that the best rated showerheads — including a model — provided a pleasing amount of water flow and met federal standards, according to David Friedman, a Consumer Reports vice president and former acting assistant energy secretary.DeLaski said he has had a hard time understanding the president’s shower concerns.“If the president needs help finding a good shower, we can point him to some great consumer websites that help you identify a good showerhead that provides a dense soak and a good shower,” deLaski said. 3624
