Maybe.The article quoted that the Center for Disease Control said the "vaping associated illness" (new term) could be linked to diacetyl for causing "hundreds" of cases.
Is this poor reporting? New findings that the CDC hasn't previously announced? I don't know. I though that our vaping industry stopped using diacetyl years ago.
"diagnosed with a disease linked" (as in previously reported in history). Maybe not "deduced from the current user base of ecig related problems".
