how long does hydrocodone show up in your system
Hydrocodone has a certain âdetection windowâ, which is the amount of time after ingestion during which evidence can be detected by a drug test. Hydrocodone detection times are unknown for blood and sweat screens. However, hydrocodone can be present in the saliva 12 â 36 hours after last dose or 2 â 4 days in the urine. Hydrocodone is also present in the hair for up to 90 days after last dose. Trusted Helpline.
