They're the hallmark of vaping — the massive clouds that sometimes come in different shapes.But how does a little e-liquid become those clouds?We're going inside an e-cigarette to find out.The devices usually have four main parts: a reservoir that holds e-liquid, a battery, a heating element and a mouthpiece.The first step is to add e-liquid to the reservoir or to attach a pre-made cartridge.The liquid is made of nicotine, flavoring, vegetable glycerin and propylene glycol. You’ll find propylene glycol in things like inhalers and fog machines. The U.S. Food and Drug Administration says it’s all safe.Next, the battery warms up the heating element and that vaporizes the e-liquid. The vapor travels through the e-cigarette, out the mouthpiece and into the lungs.When exhaled, the vapor vanishes into the air fairly quickly.The heat is low enough that it doesn't combust — or burn — the liquid.Supporters say vaporizing creates fewer dangerous compounds than combustion.The American Cancer Society says vapor can still contain harmful chemicals or substances, like volatile organic compounds, or VOCs.They cause inflammation and can make the kidneys, liver or nervous system fail.According to the American Cancer Society, vapor can also contain harmful flavoring chemicals and formaldehyde. 1312

The state of Minnesota on Tuesday launched a civil rights investigation of the Minneapolis Police Department in hopes of forcing widespread changes following the death of George Floyd, a black man who died after a white officer pressed his knee into Floyd’s neck for minutes, even after he stopped moving.Gov. Tim Walz and the Minnesota Department of Human Rights announced the filing of the formal complaint at a news conference Tuesday afternoon. The governor and Human Rights Commissioner Rebecca Lucero said they hope to reach agreement with the city to identify short-term ways to address the police department’s history of racial discrimination, and use the investigation to find long-term solutions for systemic change.Lucero said their goal is to negotiate a consent decree with the city that courts could enforce with injunctions and financial penalties. There are precedents, she said, including a 920

The US economy added only 75,000 jobs in May, a surprisingly low number that was well below what experts had predicted.Meanwhile, the unemployment rate remained at 3.6%, meaning that joblessness is still hovering near a half-century low.The report supports suspicions that the labor market is finally slowing down from its blistering pace in 2018, with revisions to the past two months subtracting 75,000 jobs. Employers have added 164,000 jobs per month on average in 2019, compared with 223,000 jobs per month last year.Still, economists had expected 185,000 jobs added in May, so 75,000 fell far short of those expectations.The share of people who have jobs or are looking for them remained the same, suggesting that the low number may stem from the difficulty of finding workers after 104 months of continuous job creation. The share of people who can't find enough hours or stopped looking for work because they couldn't find a job decreased to 7.1%, nearing the lowest level on record, 6.8% in October 2000.Wage growth also decelerated slightly, with average hourly earnings rising 3.1% from a year earlier, down from a 3.2% rate a month earlier.Health care and professional and business services were singular bright spots in the report, and have added nearly 900,000 jobs over the past year between them.But construction, mining and manufacturing showed little change from April. Manufacturing has been particularly weak over the past several months, and measures of business confidence in the sector have reached cycle lows as President Donald Trump threatens new tariffs on Mexico. 1603

There's an interesting phenomenon happening these days. A generation that came of age as marijuana came onto the scene is now rediscovering it. Marijuana has come a long way, from shady street corner dealers to lucrative businesses.And one of the fastest-growing customer bases has been baby boomers."I smoke every day as my expectorant in the morning because of a lung issue maybe from the pulmonary embolism," Keith Evanovich said, Evanovich is one of the many older Americans flocking to marijuana.A work injury the early 2000s left him partially paralyzed, and his struggles continued as he dealt with other health issues, weighing about 300 pounds at one point."I don't want to be that guy that's going to go 'hey I'm fat - I'm overweight - my waist was like 52 inches.' Being a man and having two boys and being crippled like I was, you can't do a lot," Evanovich said. But since he started using marijuana several years ago, he is in better shape. Evanovich and his wife are now making different types of cannabis products on their own."I mean it's diet too, but I mean you know if you don't exercise. I'm not saying cannabis can cure you like that," Evanovich said. Recent studies show aging baby boomers who turn to cannabis are usually seeking to treat pains and diseases that come with old age.That's true for cancer survivor Cindy Brown. But now, she's using cannabis not just for its medicinal benefits."I also put the CBD and the THC in my coconut oil for my face moisturizer, and I noticed that I have less little tiny wrinkles," Brown said. Others like Bobbie Friedman use marijuana because they can't tolerate opioids."They make me throw up. When you have pain, the last thing you want to do is throw up," said physical therapist Bobbie Friedman.But as older Americans go green in their golden years, significant questions remain: What are the side effects of long term marijuana use, and how does it affect seniors?Dr. Upinder Singh calls this "uncharted territory.""The biggest problem with it is there have been not enough definitive studies. The problem with cannabis is that it is treated totally different than any other regular medicine which comes to the market after being FDA approved," Singh said.That's because the federal government still outlaws cannabis, classified as a Schedule I drug along with heroin, which means it has no therapeutic value."Anything you put in your body can have serious repercussions. people need to be mindful and careful that nothing is without side effects or problems," Singh said. However, those who find relief from cannabis think the benefits outweigh the unknown."It gives me the quality of life. That's what I tell everybody at the gym. Hey man, there's nothing wrong with smoking weed," Evanovich said. 2782
