How Long Does THC Stay in Your System?
THC (tetrahydrocannabinol) is the main psychoactive compound in cannabis. After use, your body breaks it down into metabolites — primarily THC-COOH — which are stored in fat cells and gradually released.
| Test Type | Detection Time |
|---|---|
| Urine | 3 to 30+ days (most common) |
| Blood | 1 to 7 days (typically 1–2 for infrequent users) |
| Saliva | 1 to 3 days |
| Hair | Up to 90 days |

Factors That Influence How Long Weed Stays in Your System
- Frequency of Use: Daily users may test positive for 3–6 weeks, while one-time users may clear THC in a few days
- Body Fat: THC binds to fat, so higher body fat may extend the detox period
- Metabolism: Faster metabolism = faster clearance
- Hydration & Diet: Staying hydrated helps, but won’t flush THC completely on its own
- Test Sensitivity: Lower thresholds (like 15 ng/mL) may detect THC longer than standard 50 ng/mL screens
How Long Does Weed Stay in Urine?
Urine tests are the most common form of drug screening. If you're prepping for one, here’s what to expect:
- Occasional user (1–2 times/week): 3–7 days
- Moderate user (3–4 times/week): 1–2 weeks
- Heavy user (daily): 3–6 weeks

Fastest Way to Get Weed Out of Your System
Looking for the fastest way to pass a drug test? You’ve got a few legal and practical options:
1. Detox Drinks
Detox drinks can flush THC from the urine stream temporarily. Best used 60–90 minutes before testing with a clean window lasting up to 6 hours.
2. Synthetic Urine
Synthetic urine (for novelty or simulation use) is a pre-mixed solution that mimics real urine’s appearance, temperature, and chemical markers. Not legal in all jurisdictions — check your local laws.
3. Long-Term Natural Detox
- Exercise regularly to burn fat stores (releasing THC)
- Eat high-fiber foods to eliminate waste through digestion
- Stay hydrated and support your liver with nutrients

Will Weed Show Up in Blood Work?
Yes, but not for long. Blood tests usually detect THC for 1–2 days after last use, though heavy users may test positive for up to a week. If you're concerned about marijuana showing up on blood tests, time and hydration are your best allies.
