I never heard of anyone around me required to do a drug test for work. May be different for people carrying guns, like police and hunters, but that's because of gun license requirements.
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.

kinda obscure example. i expect most operators of heavy machinery, human transportation devices and some security professions to require some verification of abstinence. i was tested once in order to get the required permit to drive a van with elderly and disabled ppl for the red cross.
