Cocaine can typically be detected in saliva for about 1 to 2 days after last use, though some sources note a window of up to 24–36 hours for detectable levels depending on the test methodology and usage patterns.
Details and context
- Saliva tests: Most common saliva-based detection windows report cocaine or its metabolites being detectable roughly within 24 to 48 hours after use. In some cases, especially with heavy or recent use, traces can linger slightly longer, potentially approaching 2–3 days according to certain sources.
- Other tests (for context): Blood tests often detect cocaine for up to about 12–48 hours; urine tests commonly detect metabolites for 2–4 days, and sometimes longer with heavy, chronic use; hair testing can reveal use over weeks to months. These timelines illustrate variability based on amount used, frequency, metabolism, and health factors.
Factors that influence detection
- Amount and frequency of use: heavier or chronic use can extend detectability.
- Metabolic rate and individual differences: age, health, and genetics matter.
- Test sensitivity and cutoffs: different testing protocols have varying thresholds.
- Co-ingestants: alcohol or other substances can alter metabolism and detection windows.
Practical note
- If you’re preparing for a workplace or legal test, plan for the conservative end of the window (roughly 24–48 hours) to be safe, and avoid usage if a test is anticipated. For any medical, legal, or employment-related decisions, rely on the specific test type and the guidance of the testing facility.
