How long a pill stays in your system is different for everyone. There are many factors involved such as how many milligrams you are taking and how long you have been taking them. Opiates have what is called a half-life, and I think a percocet's half-life is 12 hours. Which basically means if you take 10 milligrams of percocet, 5 of those milligrams will be out in 12 hours. And of course, if you are taking 3 or 4 pills a day, then you just keep stacking the milligrams up in your system.
