It was pretty clear looking at the numbers from the beginning. A high percentage (I think it was 88%) of the people admitted to using black market THC vape cartridges. The other people were probably teens too afraid to admit it. I understand they can't give the all clear, but the headlines and statements by the CDC were vague and pointed toward nicotine products.
As an example, look at https://cdc.gov. The hero points to https://www.cdc.gov/tobacco/basic_information/e-cigarettes/s.... Why is "THC" buried here?
The way this entire thing was handled makes me not trust the CDC. The fear-mongering was/is on par with clickbait farms.
