NFL drug tests are random. And by "random," we mean that they can occur anywhere. While at the team facilities? Of course! At their very own home? It's quite possible. During a visit to a grandmother's home? Oh, you better believe it! Just ask the Redskins' Kirk Cousins, who tweeted about his on-the-spot drug testing experience this afternoon.

Let this be a lesson to all the other players in the league. If the NFL wants you to take a drug test, you will take it regardless of where you are.
