I agree that people should be cautious, but I think you are significantly misunderstanding [3].
"Toxicity" != death -- toxicity is merely "some evidence of a toxic effect" -- possibly as simple as a transiently abnormal blood test with no symptoms or sequelae, ever.
Single (accidental) doses of up to 200 mg / kg are routinely recommended to be managed at home [0], i.e. "you don't really need to go to the emergency department for this." For me, a fairly average 79kg male, this would be about 16g.
Please consult with your local poison control if you have concerns or questions!
