Coca (leaf and tea) Detection Time

Plant source of cocaine (Erythroxylum coca) · Cocaine is Schedule II; coca leaf products are controlled in the US.

Quick answer

Coca (leaf and tea) is typically detectable in urine for 2–3 days after occasional use; up to 4–5 days after heavy 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 as benzoylecgonine at 150 ng/mL urine initial / 100 ng/mL confirm.

Detection window by test type

urine
Occasional use2–3 days
Heavy useup to 4–5 days
saliva
Any use1–2 days
hair
Any useup to 90 days
blood
Any use12–48 hours

Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.

Key details

Coca leaves and coca tea contain cocaine alkaloids that are metabolised to benzoylecgonine — the same target as cocaine on standard panels.

Documented coca-tea consumption has produced confirmed positives; the Medical Review Officer process considers documented explanations, but the result is genuine rather than a false positive.

Coca is a plant source, not a separate class in testing terms: every standard panel screens the benzoylecgonine metabolite regardless of whether the source was leaf, tea or refined cocaine.

Frequently asked questions

How long does coca (leaf and tea) stay in your system?

In urine, typical detection is 2–3 days (occasional use); up to 4–5 days (heavy use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.

Will coca (leaf and tea) show up on a standard drug test?

Yes — Coca (leaf and tea) is screened on standard panels (5-panel, 10-panel, 12-panel, DOT).

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.
