Quick answer
alpha-PVP (flakka) is typically detectable in urine for roughly 1–3 days (specialised assay) after any use. It is not part of standard employment panels.
Not screened on standard employment panels.
Typical cutoff: Not reliably detected by standard panels; a dedicated LC-MS/MS assay is required. Urine is typically positive for about 1–3 days.
Detection window by test type
| urine | |
|---|---|
| Any use | roughly 1–3 days (specialised assay) |
| saliva | |
| Any use | hours |
| hair | |
| Any use | detectable on specialised testing |
| blood | |
| Any use | hours |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
alpha-PVP is a synthetic cathinone stimulant. Standard amphetamine immunoassays often do not detect it, so a dedicated assay is needed.
A negative standard panel does not rule out use; the correct test must be ordered specifically.
Detection windows for synthetic cathinones vary by compound and are best confirmed with the testing laboratory.
How alpha-PVP (flakka) is tested
Not reliably detected by standard panels; a dedicated LC-MS/MS assay is required. Urine is typically positive for about 1–3 days. Screening immunoassays are presumptive — a non-negative screen is confirmed by GC-MS or LC-MS/MS at a lower cutoff before it is reported as positive. It is not part of the standard 5-, 10- or 12-panel or DOT tests.
Legal status
Schedule I.
Frequently asked questions
How long does alpha-pvp (flakka) stay in your system?
In urine, typical detection is roughly 1–3 days (specialised assay). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will alpha-pvp (flakka) show up on a standard drug test?
No — alpha-PVP (flakka) is not part of the standard 5-, 10- or 12-panel or DOT tests. It would require a specialised or expanded assay.
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.
