Tell the difference between Percocet And Oxycodone? And how long before Leaves?

[Smitty2]

This might sound like a stupid question as Percocet basically Oxycodone with paracetamol added but SWIM is curious as should he fail as test his friend would rather admit to using a few Percocet rather than straight up Oxycodone. SWIM does definitely get tested for this stuff too as well as Hydrocodone and pretty much any other type of pain medication as well. Also in you other SWIMMERs experience what is the detection time for Oxycodone, Erowid claims 3-4 days or 72-96 hours while FirstCheck (maker of home drug test kits) say 1-2 days (24-48 hours). SWIM knows the drug has a short half life of 3-4 hours which is extremely short compared to say Lorazepam which has a 9-16 hour half life. Based on the half life alone SWIM would think that an average of 78 hours would allow plenty of time correct? Basically SWIM has a little over 4 days or 106 hours to pass a test, do you think he will be fine?
