(AP) - With CBD showing up everywhere, U.S. regulators announced Tuesday they are exploring ways the marijuana extract could be used legally in foods, dietary supplements and cosmetics.The U.S. Food and Drug Administration said it will hold a public hearing May 31 to gather more information on the science, manufacturing and sale of cannabis compounds like CBD.In the meantime, it issued more warning letters to companies for making unapproved health claims about CBD products.Products containing CBD are already in stores and sold online, so it's easy to believe there must be something special about the ingredient. But the claims are largely unproven and quality control standards don't exist.RELATED: Can using CBD products cost someone their job? A look at what we know as U.S. regulators work out what will and won't be allowed:WHAT IS CBD?CBD is one of more than 100 compounds found in marijuana. It's extracted using alcohol or carbon dioxide in factories. It's added to oils, mixed into creams and lotions and sold in candies and liquid drops.Widely sold online, CBD now is going mainstream with major retailers offering salves and balms for the skin. Prices range from to 0 an ounce at high-end shops.CBD often comes from a cannabis plant known as hemp, which is defined by the U.S. government as having less than 0.3 percent THC. That's important because THC is what causes marijuana's mind-altering effect.CBD doesn't get people high, although it may be calming. Keep in mind some CBD products may contain THC, whether or not the label says so.RELATED: CBD-infused foods become rising trend in 2019People drug tested for work, addiction programs or because they take prescription opioids should take note: CBD products have caused people to fail urine drug screens.IS IT A MIRACLE CURE?If you believe the hype, CBD treats pain, relieves anxiety and both helps you sleep and keeps you focused.Most claims are based on studies in rats, mice or in test tubes. Some human research has been done, but in small numbers of people.One exception: For two rare seizure disorders, the evidence for CBD was strong enough to convince the FDA to approve GW Pharmaceutical's drug Epidiolex, which contains a purified form.The FDA announced Tuesday it has sent warning letters to three companies marketing products with what outgoing Commissioner Scott Gottlieb called "egregious, over-the-line claims" for CBD's effects on cancer, Alzheimer's disease, fibromyalgia and drug addiction. Gottlieb said the agency "won't tolerate this kind of deceptive marketing to vulnerable patients."RELATED: CVS Pharmacy selling cannabis-based products in stores in California, 7 other statesOnly drugs that have been reviewed by the FDA as safe and effective can make claims that they treat or prevent diseases or medical conditions. Many CBD producers attempt to sidestep the issue by using only vague language about general health and well-being.ANY SIDE EFFECTS?Scant research means not much is known about side effects either. In epilepsy research, CBD changed the way the body processed other drugs. That suggests CBD could interact with medications in ways we still don't know about.The most common side effects of the CBD drug Epidiolex include sleepiness, decreased appetite, diarrhea, increases in liver enzymes, exhaustion, rash and infections. FDA's Gottlieb noted Tuesday the potential for liver injury and other risks can be handled with medical supervision but less is known about how that would be managed without oversight. And there are questions about overlap if multiple CBD products are used.IS IT LEGAL?For now, the agency has said CBD is not allowed as an ingredient in food, drinks or dietary supplements.In stating its position, the FDA cited a provision of the law prohibiting food makers from using active drug ingredients or those that are the subject of substantial research. But the agency doesn't have the resources to police all the CBD products that are already available, said Marc Scheineson, a former FDA official.RELATED: Creator of Jelly Belly releases CBD-infused jelly beans"They're not going to pull a thousand products from the market," he said.The FDA's authority is over interstate commerce, and local officials have taken differing approaches. In New York, Los Angeles and elsewhere, officials are warning eateries to stop selling it in food and drinks. Maine passed a law allowing it in foods and other products in the state.Skin creams and cosmetics may be on safer footing with the FDA, but that too remains uncertain, said Camille Gourdet of RTI International, a nonprofit research institute in Durham, North Carolina. Though cosmetics aren't subject to premarket approval by the FDA, they could run afoul of regulations if they make specific health claims.Marijuana itself is illegal under federal law; most states that have legalized it allow marijuana-infused foods and candies, called edibles.ARE CBD LABELS ACCURATE?What you buy may contain much less CBD than the label states — or much more. It may include more THC than you want and it may be contaminated with mold or pesticides. Ask to see testing reports.A 2017 study in the Journal of the American Medical Association found 70 percent of CBD products were mislabeled. Researchers used an independent lab to test 84 products from 31 companies."You're really flying by the seat of your pants when you buy this stuff," said author Marcel Bonn-Miller of University of Pennsylvania.A product labeled as containing 100 milligrams of CBD may only have 5 milligrams or it may have 200, said Bonn-Miller, now an adviser for a company that sells CBD and other cannabis products. He did not work in the industry when he did the research."I wouldn't trust any of it until I knew independently it was safe," Bonn-Miller said.WHAT'S AHEAD?CBD research is planned or underway for cancer, autism, diabetic neuropathy, fibromyalgia, chronic pain, alcoholism with PTSD and psychiatric conditions. Results will take years, but some people aren't waiting."They are vulnerable and really hoping to feel better," said Karen Hande, a nurse practitioner at Vanderbilt-Ingram Cancer Center in Nashville.She became an expert in CBD because so many of her cancer patients were trying it. She tells them the evidence isn't enough to back the claims, but "they want to believe something is going to work." 6383

(CNN) -- For six months now, the days have grown shorter and the nights have grown longer in the Northern Hemisphere -- but that's about to reverse itself.Winter solstice, the shortest day of 2019, will be Saturday, December 21. Or it will be Sunday, December 22. Which day is it for you? It all depends on your time zone.CNN meteorologists Dave Hennen, Judson Jones and Brandon Miller help us understand the science and timing behind the solstice. And then we'll discover some traditions and celebrations around the world that could inspire a travel adventure.The science and timing behind a winter solsticeThe winter solstice marks the shortest day of the year in the Northern Hemisphere, when the sun appears at its most southerly position, directly overhead at the faraway Tropic of Capricorn.It's the reverse in the Southern Hemisphere. There, it marks the longest day of the year -- and the beginning of summer in places such as Argentina, Namibia and New Zealand.When exactly does it occur?The solstice usually takes place on December 21. The time that the solstice occurs and the day itself shifts because the solar year (the time it takes for the sun to reappear in the same spot as seen from Earth) doesn't exactly match up to our calendar year.If you want to be super-precise in your observations, the exact time of the 2019 winter solstice will be 4:19 Universal Time on Sunday. Here are some examples of when that will be for local times around the world:-- Tokyo: 1:19 p.m. Sunday-- Dubai: 8:19 a.m. Sunday-- Rome: 5:19 a.m. Sunday-- Dakar, Senegal: 4:19 a.m. (same as Universal Time)-- Philadelphia: 11:19 p.m. Saturday-- Seattle: 8:19 p.m. Saturday-- Honolulu: 6:15 p.m. SaturdayIf you don't live in one of these time zones above, the website EarthSky has a handy conversion table for your time zone. You might also try the conversion tools at Timezoneconverter.com or WorldTimeServer.com.What causes the winter solstice to even happen?Because the Earth is tilted on its rotational axis, we experience seasons here on Earth. As the Earth moves around the sun, each hemisphere experiences winter when it's tilted away from the sun and summer when it's tilted toward the sun.Wait. Why is the Earth tilted?Scientists are not entirely sure how this occurred, but they think that billions of years ago, as the solar system was taking shape, the Earth was subject to violent collisions that caused the axis to tilt.What other seasonal transitions do we mark?The equinoxes, both spring and fall, occur when the sun's rays are directly over the equator. On those two days, everyone has an equal length of day and night. The summer solstice is when the sun's rays are farthest north over the Tropic of Cancer, giving us our longest day and summer in the Northern Hemisphere.Winter solstice traditions and celebrationsIt's no surprise many cultures and religions celebrate a holiday -- whether it be Christmas, Hanukkah, Kwanzaa or pagan festivals -- that coincides with the return of longer days.Ancient peoples whose survival depended on a precise knowledge of seasonal cycles marked this first day of winter with elaborate ceremonies and celebrations. Spiritually, these celebrations symbolize the opportunity for renewal, a shedding of bad habits and negative feelings and an embracing of hope amid darkness as the days once again begin to grow longer.Many of the ancient symbols and ceremonies of the winter solstice live on today.Here are five extraordinary destinations where you can experience something magical during winter's relentlessly long night:UNITED KINGDOM: Cornwall and StonehengeBetter known for pirates than the solstice, the town of Penzance on the southwest coast of England has revived a delightful array of Cornish solstice events leading up to winter solstice. The Montol Festival is a fun mix of pagan customs and more recent Christmas traditions that were once common throughout Cornwall.Early in the week, join in caroling and other events. On the solstice, referred to here as Montol Eve, get your dancing card ready for the Guise, a community dance in which people dress in masks and other "topsy-turvy" disguises based on a 19th-century tradition of the rich dressing in rags while poorer citizens effected a "mock posh" look.You can also don your finery for torchlit processions. The merrymaking only continues when the revelers disperse to pubs around town.With some planning, it's also possible to incorporate a trip to Stonehenge, the UK's most famous site for solstice celebrations. On the winter solstice, visitors have the rare opportunity to enter the towering, mysterious stone circle for a sunrise ceremony run by local pagan and druid groups.The trip from Penzance to Stonehenge takes less than four hours by car, making it entirely feasible to spend the night in Salisbury, the nearest town to Stonehenge, and rise before dawn for the ceremony among the stones.SWEDEN: Santa Lucia, yule and aurora borealisSweden is rich with solstice traditions. Elements of the yule, Northern Europe's a

With many Americans avoiding getting on board passenger jets amid the spread of coronavirus, United Airlines has a plan to continue operating some of its fleet of planes. United Airlines said that it is using some of its largest planes as cargo planes. United Airlines said the flights will be used to carry "critical goods."United said it is using its Boeing 777 and 787 fleet to run 40 charter flights each week, and is looking to add more routes. "Connecting products to people around the world is the United Cargo mission," said United Cargo President Jan Krems. "That role has never been more crucial than during the current crisis. Our team is working around the clock to provide innovative solutions for our customers and support the global community." 771

SAN DIEGO (KGTV) - Amid the Red Flag conditions, some warnings of possible power shutoffs caught some by surprise in Torrey Highlands.Terrie Rollins has lived at her home on Caminito Vistana for nearly 20 years. On Wednesday night, for the first time ever, she received an email from SDG&E warning of a possible shutoff."Confusion, worry. Wondering how I'm going to get everything done," said Rollins.Rollins's husband suffers asthma and requires an air purifier in the home. Rollins herself lives with a lung condition and needs to plug in a nebulizer for half an hour every day to clear her lungs."Didn't sleep much last night wondering what's going to happen," said Rollins.Rollins says a hotel is costly and is concerned no hotel will accept her two dogs and parrot. Amid mounting wildfire costs and liability for utilities across the state, SDG&E - armed with high-tech tools - continue to become more proactive with wildfire prevention. That has translating into more widespread shutoff warnings. Rollins fears the shutoff warnings could be her 'new normal.’"Every time there are high winds, do I have to get a hotel? It's stressful," said Rollins. 1171

(AP) — Researchers are concerned about reports from Britain and South Africa of new coronavirus strains that seem to spread more easily. Scientists say it's unclear if that's true. And for now, they don't think the new strains cause more severe COVID-19 illness or pose any concern for vaccines. Viruses naturally evolve as they move through the population. One strain recently detected in England has a lot of changes to the spiky protein that's targeted by current vaccines. The advice to the public remains the same — wear a mask, wash hands often, and keep social distance to avoid catching and spreading the virus. 627
