THC can stay in urine for varying lengths of time depending on usage frequency, body fat, metabolism, and other factors. Here are general detection times based on Reddit user experiences and medical sources:
- One-time or occasional use: THC metabolites are typically detectable in urine for up to 3 days, sometimes up to a week if usage was slightly more frequent or amount slightly higher
- Moderate use (several times a week): Detection can last from about 5 to 15 days, with some reports suggesting around 10 days on average
- Heavy or daily use: THC can remain detectable in urine for 30 days or more, sometimes up to 90 days in extreme cases, especially for long-term heavy users due to THC being stored in fat cells and released slowly
Additional points from Reddit discussions include:
- Hydration, exercise, and body fat percentage influence how quickly THC is eliminated; staying hydrated and active may help reduce detection time
- Using at-home THC urine test kits can help monitor when THC levels drop below detectable thresholds
- For many moderate users, about 2 to 3 weeks of abstinence is often sufficient to test negative on a urine drug test
In summary, THC can be detected in urine from a few days for occasional users up to several weeks or months for heavy users. Most moderate users clear THC within 10 to 30 days, but individual factors vary significantly.
