Earlier quoted context omitted.
> This tiny detail makes the difference why employer-mandated drug tests are not a thing in Germany like it is in the US. I assume that Germany does drug testing for safety-related roles? Crane operators, pilots, nuclear plant operators? It would be wild if they don't.
last nuclear plant got shutdown a few weeks ago, but, yes, drug testing is a thing (but not popular) even for some office jobs.
A drug test may be legal, or suggested, when there is reasonable suspicion someone was high during work hours. Maybe air traffic controllers and similar professions need to be evidently clean. Otherwise I don't think drug tests are legal in Germany. Even asking about consumption is illegal in most cases.
