Cody's Lab on YouTube drank 17 mg of cyanide for a video, but not surprisingly it's now private. Quotes include:
* It tastes like baking soda
* I've got a tremor [in my arm] and my breathing is slightly more rapid
Cyanide fortunately can't accumulate, so it's far less spooky than heavy metals (lead, chromium, mercury), perfluoroalkanes (PFAS), or some other strange organic molecules that might cause cancer.
