In truth I have never ever heard of JSer's getting a random. It would likely not be possible with an offline JSer since the host airline has no authority over him, or mechanism to assign and process a random. If you're online and want to drink in the back, you should obviously nonrev anyway.
If there was an accident/incident, and you were involved in flight operations (ie in the cockpit) I'm sure the FAA could do substance testing but I can't imagine they could get that organized soon enough. Besides, you'd be under no obligation to wait around while they figured it out.
In today's environment probably best to stick to the letter of the law., even if offered hospitality.
