Michigan’s Department of Health and Human Services is looking into six cases of breathing illnesses that could be linked to vaping.
They say most have been a severe respiratory illness in people from 19 to 39 years old.
More than 200 possible cases of e-cigarette related illnesses have been reported in at least 22 states.
Illinois reported one death last week.
If you vape, the DHHS says you should get to a doctor if you develop shortness of breath, chest pain, cough, fever, nausea, or vomiting.
