But then it doesn’t depend on the level actually. If something toxic has a half life of a billion years then it shouldn’t be used in production, no matter in what amount/at what levels. Cocaine will degrade at some point and also not stay in your system forever so I would argue that there can be a safe level of cocaine in drinking water. (I mean it still shouldn’t be there, but it doesn’t cause trouble on the grander scheme of things.)
