Quick answer
Kava is typically detectable in urine for not tested; no standard interference after any use. It is not part of standard employment panels.
Not screened on standard employment panels.
Typical cutoff: Never screened on standard panels.
Detection window by test type
| urine | |
|---|---|
| Any use | not tested; no standard interference |
| saliva | |
| Any use | n/a |
| hair | |
| Any use | n/a |
| blood | |
| Any use | n/a |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
Kava drinks don't register on drug tests — kavalactones aren't screened anywhere in workplace testing. Search interest spiked after kratom coverage; the two plants differ completely here.
Frequently asked questions
How long does kava stay in your system?
In urine, typical detection is not tested; no standard interference (any use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will kava show up on a standard drug test?
No — Kava 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.
