If you failed a work drug test would you just be fired or would the cops be called as well?

You "asking for a friend" right?

I'd just tell el coppos I'm royalblue and they can go fuck themselves.

i don't do drugs or work

I would never get drug tested

Never seen random testing at work

If anyone failed a random drug test at our company, they would be forbidden on-site work at our clients' government facilities. A second failure would mean termination.

I can't imagine that they have a legal right to disclose any personal health information to the police.
You'll be dismissed.
Legally speaking I don't even think they can disclose that information to a future employer
