Understanding THC and How It Lingers in Your Body…THC Detection Times
THC, the main psychoactive compound in cannabis, is fat-soluble. That means it doesn’t just flush out quickly—it stores in your body’s fat cells and releases slowly over time.
From my experience harvesting potent strains like Gorilla Glue, I’ve seen how higher THC levels can mean longer detection. Your liver breaks THC into metabolites like THC-COOH, which tests often look for. These hang around way longer than the high itself.
Key Factors That Influence How Long Cannabis Stays in Your System
Several things affect clearance:

- Frequency of use: Single use clears faster than daily habits.
- Body fat percentage: More fat means longer storage.
- Metabolism and hydration: Faster metabolism helps, but still takes time.
- Potency and dosage: Stronger buds from high-THC seeds (Like I sell ;0) linger longer.
- Method of consumption: Edibles process slower than smoking.
Lighter sessions clear quicker, and it makes a difference. Heavy users might see THC-COOH for weeks!
Detection Windows: Urine, Blood, Saliva, and Hair Tests in 2025

Here’s a realistic breakdown based on current data:
- Urine: Most common—3-7 days for occasional use, up to 30+ days for chronic.
- Blood: 12-24 hours for active THC, longer for metabolites in heavy users.
- Saliva: 24-72 hours, great for recent use.
- Hair: Up to 90 days, but less reliable for light consumption.
How Your Body Metabolizes THC: A Quick Breakdown

THC enters your bloodstream fast, peaks quick, then stores in fat. About 65% exits via feces, 20% urine—the rest releases gradually.
Fast autos like Sour 60 and lighter sessions clear quicker. But potent hybrids? Plan ahead.

Tips to Support Natural Clearance (And Myths Busted)
Drink lots of water, exercise, eat healthy—these support your body naturally. However, no detox kits guarantee faster clearance; time is key.
From my experience, choosing lower-potency strains helps if clearance matters.
