How long does marijuana stay in saliva reddit
Detection Window in Saliva
| User Type | Detection Time |
|---|---|
| Occasional users | 24–72 hours |
| Frequent users | Up to 7 days (sometimes longer) |
Key Factors Affecting Detection
- Usage Frequency
- More frequent use = longer detection window.
- Consumption Method
- Smoking/vaping: Leaves THC residue in the mouth → higher saliva detection.
- Edibles: Lower oral THC presence → shorter detection time.
- Test Sensitivity
- Instant tests (e.g., swabs): Detect for 12–48 hours.
- Lab tests: Can detect up to 72+ hours.
- Personal Variables
- Metabolism, oral hygiene, and hydration can impact how fast THC clears.
What Reddit Users Say
- Most casual users pass saliva tests after 2–3 days.
- Heavy users often need 5–7 days or more.
- Cleaning the mouth (brushing, mouthwash) may help slightly but isn’t foolproof.
- Some report testing negative after 24 hours, others still test positive after 4+ days—it varies.
Bottom Line
- Occasional use: Safe zone ~72 hours.
- Frequent/heavy use: Wait at least 5–7 days.
- No guaranteed way to “flush” THC fast—time is the only reliable factor.
For high-stakes tests, err on the side of caution and allow more time.
