How Long Does Weed Stay in Your System? Drug Testing & Detection Times
Many cannabis users wonder, how long does THC stay in my body? Whether you're preparing for a drug test or just curious about cannabis metabolism, understanding the detection window is important.
How THC is Metabolized
When you consume cannabis, THC enters the bloodstream and is processed by the liver, where it’s broken down into metabolites like THC-COOH. These metabolites are what drug tests detect.
Detection Times by Test Type
| Drug Test Type | Detection Window |
|---|---|
| Urine Test | 3-30 days (varies based on use) |
| Blood Test | 1-2 days (longer for heavy users) |
| Saliva Test | 24-72 hours |
| Hair Test | Up to 90 days |
Factors That Affect THC Detection
- Frequency of Use – Occasional users clear THC faster than daily users.
- Metabolism – A faster metabolism may process THC more quickly.
- Body Fat – Since THC is stored in fat, higher body fat may prolong detection times.
- Hydration & Diet – Drinking water and eating a healthy diet can slightly speed up excretion.
How to Detox THC from Your System
While no method guarantees instant detox, these can help:
- Hydration & Exercise – Staying active and drinking water helps metabolism.
- Diet & Fiber – Eating a clean diet with fiber helps eliminate THC through digestion.
- Detox Drinks & Supplements – Some people use detox kits, but effectiveness varies.
Key Takeaways
- Casual users may clear THC in 3-7 days.
- Frequent users could test positive for up to 30 days.
- Hair tests detect cannabis use for months.
- Hydration, exercise, and time are the best ways to clear THC.
If you’re facing a drug test, be aware of your usage patterns and detection times.
