The US Centers For Disease Control (CDC) says there is no evidence that an infectious diseases struck dozens of people who were sickened with a mysterious lung ailment after vaping.

The raises the possibility that vaping itself is to blame for putting the patients in the hospital.  Almost a hundred people, mostly teens and young adults, came down with severe lung illness tied to vaping since 28 June.  The CDC is working with health officials in Illinois, California, Indiana, Minnesota, and Wisconsin whicch on its own logged 30 such cases.  Other states, including New York and New Jersey, have issued health advisories regarding vaping-linked lung illnesses.

The patients complained of coughing, shortness of breath, and fatigue.  Some had serious breathing difficulties that required ventilation.

Juul Labs is the biggest e-cigarette company in the US, accounting for 35 percent of the market.  The company released a statement which read, "Like any health-related events reportedly associated with the use of vapor products, we are monitoring these reports."

With no regulation over the vaping phenomenon, Juul hinted that the wild, wild west of e-cigarettes had gotten too wild:  "These reports reaffirm the need to keep all tobacco and nicotine products out of the hands of youth through significant regulation on access and enforcement.  We also must ensure illegal products, such as counterfeit, copycat, and those that deliver controlled substances, stay out of the market and away from youth."
