Numerous, though not all, of the clients who have actually fallen ill had actually utilized cannabis-derived vaping items, and some had actually likewise utilized nicotine-containing items. A smaller sized group reported utilizing nicotine just.

No contagious causes have actually been recognized, and the CDC informed press reporters that the “lung diseases are most likely related to a chemical direct exposure.” However it is prematurely to determine a single item or compound that prevails to all cases, the CDC stated, based upon initial research study likewise released Friday.
