Quick answer
Opium is typically detectable in urine for 2–4 days after occasional use; up to about 7 days after regular use. It is screened on standard 5-panel, 10-panel, 12-panel, DOT drug tests.
Screened on: 5-panel 10-panel 12-panel DOT
Typical cutoff: Screened in the opiates slot at 2,000 ng/mL urine initial / 2,000 ng/mL confirm.
Detection window by test type
| urine | |
|---|---|
| Occasional use | 2–4 days |
| Regular use | up to about 7 days |
| saliva | |
| Any use | 1–2 days |
| hair | |
| Any use | up to 90 days |
| blood | |
| Any use | hours to about 1 day |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
Opium is the dried latex of the opium poppy and contains morphine, codeine and thebaine. Standard panels detect it through the opiates slot, which targets morphine and codeine.
Heroin use is distinguished from other opiates by the 6-MAM metabolite (6-monoacetylmorphine), which is specific to heroin and present only briefly.
Semi-synthetic opioids such as oxycodone, hydrocodone and buprenorphine often need their own assay strips and may not appear in the classic opiates slot.
False positives & cross-reactivity
- Poppy-seed foods can contain trace morphine and codeine; the 2,000 ng/mL cutoff is set high enough that ordinary consumption rarely produces a confirmed positive, and the MRO process handles documented dietary exposure.
Frequently asked questions
How long does opium stay in your system?
In urine, typical detection is 2–4 days (occasional use); up to about 7 days (regular use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will opium show up on a standard drug test?
Yes — Opium is screened on standard panels (5-panel, 10-panel, 12-panel, DOT).
Can anything cause a false positive for opium?
Poppy-seed foods can contain trace morphine and codeine; the 2,000 ng/mL cutoff is set high enough that ordinary consumption rarely produces a confirmed positive, and the MRO process handles documented dietary exposure.
How accurate are these detection windows?
They are typical ranges from published literature and assay documentation, not guarantees. Clearance depends on dose, frequency, metabolism and the specific test cutoff used.
