so what would heppen to someone who had been over to Amsterdam for a weekend and got tested the week after ? they have done nothing illegal
not illegal but if there are drug tests there is probably something in the contract to say you can't take them (regardless of if it's legal or not)
sellafield do random drug tests but they are a waste of time, id say about 30% of the staff there are regular drug users.
they have a policy where if you are caught, you only get a warning. so no one cares unless they have been caught before cause they know they'll get away with the first one
