I think it depends on the scenario. I've had plenty of patients presenting with negative UDS several days after leaving a residential "detox" program who are white-knuckling it with severe cravings and impending relapse. I have no concerns inducing them. Your scenario is a little different. Anyone snorting a significant amount of hydrocodone, should still have a positive UDS 24 hours after last use.
