If you want a new conspiracy theory, have a look at the number of reports of people in hospital and/or dying from a lung condition/pneumonia that was attributed to vaping over the year and months immediately prior to this.
'Commonly reported symptoms include shortness of breath, cough, fatigue, body aches, fever, nausea, vomiting, and diarrhea. Additional symptoms may include chest pain, abdominal pain, chills, or weight loss.'
'Pulmonary infiltrate, such as opacities on plain film chest radiograph or ground-glass opacities on chest computed tomography '
'patients in narratives including the following:
Dehydration from nausea, multifocal pneumonia, sepsis, acute respiratory failure with hypoxemia, and blood clots, necessitating a medically induced coma and removal of fluid from the lungs'
Have fun.
