Quick answer
Morphine is typically detectable in urine for 1–3 days (chronic up to 4) after any 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: Standard opiate strip: 2,000 ng/mL initial/confirm.
Detection window by test type
| urine | |
|---|---|
| Any use | 1–3 days (chronic up to 4) |
| saliva | |
| Any use | 1–2 days |
| hair | |
| Any use | up to 90 days |
| blood | |
| Any use | ~12–24 h |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
Morphine anchors the classic opiate panel. Hospital IV/PCA use creates the same positives as pills — bring discharge paperwork for the MRO.
Poppy seeds contribute real morphine; the 2,000 ng/mL cutoff exists to tolerate dietary exposure.
False positives & cross-reactivity
- Poppy-seed true positives (dietary); cutoffs calibrated for it.
Frequently asked questions
How long does morphine stay in your system?
In urine, typical detection is 1–3 days (chronic up to 4) (any use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will morphine show up on a standard drug test?
Yes — Morphine is screened on standard panels (5-panel, 10-panel, 12-panel, DOT).
Can anything cause a false positive for morphine?
Poppy-seed true positives (dietary); cutoffs calibrated for it.
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.
