The city of Milwaukee Health Department is urging residents to stop using all vaping products immediately.
So far, doctors in Wisconsin have confirmed 16 cases of chemical pneumonia that they believe are related to vaping. The only commonality at this point is that everyone impacted reported vaping or dabbing vaping marijuana oils and extracts in the weeks before becoming sick.
Symptoms of chemical pneumonia include coughing, shortness of breath and nausea.
Across the country, there are nearly 200 cases.
The vaping industry has responded in part by blaming black market products.
