i have paid twice to hear two different opinions because of the situation im in. just to make sure and unfortunately the answers were completely different lol.... the other opinion i got for the same question was that...while the half life is 4.5 hours this is only the time it takes for half the medicine to be expelled from the plasma not the amount of time it takes for it to be disregarded through the urine. and that it would take longer than 24 hours for your body to actually have processed enough to make ur levels detectable in your urine..... what is your opinion on this.... and can a lab test prove impairment or time of use on urinalysis

Brief Answer: My answer does not change. Detailed Answer: My answer was very specific and not theoretical. After a single oral dose of Oxycodone 20 mg Oxycodone can be detected in the urine within 2 hours and can continue to be detected in the urine upto 30 hours after the dose.
