. You didn't state the milligrams of either drug. But you can easily (even under a Dr.s supervisision) develop a physical addiction to either...I currently have a Rx for 5 mg norco, was being prescribed 10mg but they were making me too tired and NO i wasn't abusing them. personally, I think Percocet is a stronger, higher class narcotic.
