"The American Lung Association echoes the Milwaukee Health Department's warning today to e-cigarette users: 'Stop using any vape and/or e-cigarette devices immediately", the group said in a statement to WISN 12 News.
Nationwide, the Center for Disease Control said they are investigating more than 194 cases with one reported death in IL.
US public health officials warned Americans who aren't already smokers to avoid e-cigarettes and other vaping devices after a mysterious outbreak of a severe lung disease emerged in recent weeks, which has sickened at least 215 people across 25 states and been linked to at least one death.
Many people believe vaping is safer than traditional cigarettes and tobacco, which kill 8 million people each year due to cancer, health disease and other conditions, according to the World Health Organization.
Vaping nicotine and/or THC cartridges seems to be a common link between victims.
"We continue to learn more about the health effects associated with e-cigarettes". In many cases, patients reported using vaping products that included cannabis or THC, the active ingredient in marijuana, before falling ill.
The CDC and Food and Drug Administration warned the public not to buy vaping products off the street.
"While the exact cause of the vaping-related illnesses is still unknown, doctors who have treated patients with the illness believe it could be linked to the liquid that's used in all e-cigarettes, known as vape juice", Degette's office said in a statement.
Even as all this is happening, headlines from major national news outlets virtually never mention the THC connection, and if they do, it's buried hundreds of words deep in an article blaming simply "vaping" as the cause.
A spokesperson for King County Health confirms there have been no local cases, but adds that the agency has "sent an alert out to local health care providers to be on the lookout and report any suspected cases to us".
Health officials are still conducting interviews with patients.
Some 200 people have come down with serious respiratory illnesses in recent months that are linked to street-purchased vape products. However, e-cigarette makers and other health experts have pushed back, noting that the issue is clearly with dubious products, not vaping generally.
