Hello, just say I was prescribed oxycodone/APAP pills by a doctor for pain. Just say the indication on the medicine was use as needed for back pain. If I did not use it at all on weekdays and saved up the pills for one big CWE on Saturdays, can they tell that I used one big dose on the weekend and did not actually use one or two pills a day? Say if my blood or urine was sent to a lab etc?
