I'm not sure anyone in the media has said anything negative about the drug.
There definitely was. A bunch of non-scientist journalists probably went and Googled chloroquine and wrote stories about what the found.
Here's one from Bloomberg highlighting the so-called toxicity: https://www.bloomberg.com/news/arti...d-by-trump-musk-can-kill-with-just-two-grams?
And one from WaPo following the same angle: https://www.washingtonpost.com/outlook/2020/03/25/chloroquine-coronavirus-toxic-malaria/
There were more. The truth is that chloroquine is as safe as any other prescription drug. If I told this WaPo reporter that you could kill yourself by taking ~12 or so Tylenol in a day, I wonder what they would say...
Arguably the press coverage of the dude in Arizona who killed himself on fish tank cleaner was in the same vein.
