A mother is warning others about the dangers of smoking and vaping after a devastating diagnosis or incident involving her child. The specifics of the incident vary, with some reports mentioning a child being put into an induced coma, another developing "popcorn lung", and a warning after a child bought a vape from a stranger. The mother's warning appears to be part of a broader concern about the risks associated with vaping, although the exact circumstances and details of her case are not consistent across reports.
