used methadone nights ago. will it still show up in urine?
Methadone is a strange drug. The length of time that you've used methadone and the amount determines how long. If you've just taken it once a week, then something around 2 to 6 days depending on your size and metabolism. If you've taken the drug for a very long time, over the course of years, it builds up in your liver (not harmful though), and just sort of collects, increasing the time (and potency, kinda counteracting tolerance) that it would take for you to get the drug entirely out of your system, would take... a very long time, but that totally depends on all of the factors listed above.
Hope that this is of some help!
