I would just add that based on pharmacology,
hydrocodone (contained in vicodin, lortab, norco) is about 0.6 times the strength of
morphine (i.e., 10 mg of morphine equals 16 mg of hydrocodone). Oxycodone (contained in percocet, roxicodone, oxycontin) is about 2 times the strength of morphine (i.e., 10 mg of morphine equals 5 mg of oxycodone). Therefore, 5 mg of oxycodone is about 16 mg of hydrocodone so oxycodone is about 3 times stronger than hydrocodone.
