How do you get oxycodone out of your system faster?

The best thing to do is go to a health food store immediately and buy a detoxification system (make sure it says it will detoxify your liver on package) they usually keep the drug detoxification kits behind the counter for stuff like this so you will have to ask, drink more water than you have ever drank in your life, drink coffee to highten your metabolism and do a lot of exercise, increasing your metabolism as well, this will increase the drugs ability to flush from your system quicker. Oh and try not to do drugs before the test.
