The one that always gets me is that chlorine is a poisonous gas and sodium explodes in contact with air, but we’re supposed to believe that sodium chloride is safe to consume?https://twitter.com/jimcarrey/status/616051925859987456 …
Carrey's wrong because heavy metals are cumulative poisons. A tiny one-off dose has negligible impact. It's things like breathing lead or mercury fumes regularly for years that has bad health effects.
