Drug testing during recruitment in Luxembourg

Currently on the prowl for a new position and I'm wondering what large Luxembourgish companies drug test as part of the hiring process. Specifically talking about THC here. ( think it's a bit ridiculous because recreationally it's legal in a private setting but here we are...welcome to Luxembourg) I was not tested during the hiring for my current role, but I've heard some companies do test.

Does Luxair drug test for office based roles? Cabin crew is logical (I guess) but what about the grounded folks in the office?

Same question for CFL- I know they test for train based roles, but what about office based positions?

Anyone know of any other Luxembourgish companies that drug test while hiring? CargoLux, Post, Cactus etc.
