How long does methadone stay in blood stream?

Answer 1

1. I take methadone on the streets 40 mgs every couple of days and i have stopped using it for a week thinking i would clear my urine test the following week i still failed for this drug 14 days later three weeks later the metabolites were low enough where it was finally undetectable in my system same with benzodiazapine so be careful and prepared the best way to pass is to not use for a month before a drug test due to the fact methadone has a very long half life which can kick in days later.

Answer 2

In a urine test they probably would be able to detect it up to 48 hours later or more,depends on how much you had and how much fluid goes through your system,so it could go up to 72 hours or more.

I would like to add to this answer above, I took ONE 10mg methadone pill and failed a week later, have NEVER taken it before or after. Absolutely do NOT expect methadone to be out of your system and pass a urine test any LESS than 10 TEN days. No amount of water will help (I drank over a gallon of water for 3 days each day) prior to a 10 panel urine test 8 days later still FAILED. To protect yourself, purchase a test and test yourself. If in doubt do NOT take a urine test for a job, or any other reason BEFORE you test yourself.

Answer 3

Methadone can usually be detected up to 3 to 5 days on a drug screen.

Answer 4

Answer 5
