Understanding Weed in Your System: How Long Does Weed Stay?
The length of time that weed stays in your system varies based on factors like frequency of use, body fat percentage, metabolism, and test type. THC can be detected in urine for up to 3 days after single use in occasional users, up to 15 days for regular users, and longer for heavy users. Blood tests detect THC for 1–2 days, hair tests up to 90 days, and saliva tests for 24-72 hours. These timeframes are approximate and can differ from person to person.
