How Long Does Cannabis Stay in Your System?
Cannabis can stay in the body for days to weeks, depending on factors like frequency of use, metabolism, and testing method. Knowing how long THC remains in your system is important for drug testing and responsible consumption.
How the Body Processes THC
- Smoking/Vaping – Absorbed into the bloodstream quickly, peaking within minutes.
- Edibles – Processed through the liver, lasting longer in the body.
- Tinctures – Absorbed through the mouth or stomach, with effects lasting several hours.
Detection Times by Test Type
| Test Type | Detection Window |
|---|---|
| Urine Test | 3–30+ days |
| Blood Test | 1–7 days |
| Saliva Test | 24–72 hours |
| Hair Test | Up to 90 days |
Factors That Affect How Long THC Stays in Your System
- Frequency of Use – Heavy users retain THC longer than occasional users.
- Body Fat Percentage – THC is stored in fat cells, so higher body fat may prolong detection.
- Metabolism Rate – Faster metabolisms clear THC more quickly.
- Hydration & Diet – Staying hydrated may help remove metabolites faster.
Can You Speed Up THC Elimination?
While no method guarantees rapid THC removal, you can try:
- Drinking plenty of water – Helps flush metabolites naturally.
- Exercising – Burns fat where THC is stored, though this may temporarily increase THC levels in blood.
- Eating a healthy diet – Supports metabolism and detoxification.
Key Takeaways
- Detection time varies based on use frequency, metabolism, and test type.
- Urine tests are the most common and can detect THC for up to a month.
- Detox methods are not foolproof, and time is the best way to clear THC from your system.
If you have an upcoming drug test, abstaining for at least a month is the safest way to ensure clearance.
