It was the arrival of the second man in his early 20s gasping for air that alarmed Dr. Dixie Harris. Young patients rarely get so sick, so fast, with a severe lung illness, and this was her second case in a matter of days.To get more news about Best Smoking Alternative, you can visit univapo official website.

Then she saw three more patients at her Utah telehealth clinic with similar symptoms. They did not have infections, but all had been vaping. When Harris heard several teenagers in Wisconsin had been hospitalized in similar cases, she quickly alerted her state health department.

As patients in hospitals across the country combat a mysterious illness linked to e-cigarettes, federal and state investigators are frantically trying to trace the outbreaks to specific vaping products that, until recently, were virtually unregulated.

As of Aug. 22, 193 potential vaping-related illnesses in 22 states had been reported to the Centers for Disease Control and Prevention. Wisconsin, which first put out an alert in July, has at least 16 confirmed and 15 suspected cases. Illinois has reported 34 patients, one of whom has died. Indiana is investigating 24 cases.

Lung doctors said they had seen warning signs for years that vaping could be hazardous, as they treated patients. Medically it seemed problematic, since it often involved inhaling chemicals not normally inhaled into the lungs. Despite that, assessing the safety of a new product storming the market fell between regulatory cracks, leaving doctors unsure where to register concerns before the outbreak. The Food and Drug Administration took years to regulate e-cigarettes once a court determined it had the authority to do so.

"You don't know what you're putting into your lungs when you vape," said Harris, a critical care pulmonologist at Intermountain Healthcare in Salt Lake City. "It's purported to be safe, but how do you know if it's safe? To me, it's a very dangerous thing."
