Figuring out how long weed stays in your system is a question many people ask, whether it's for a job interview, a medical test, or simply out of curiosity. It's a practical and widely appreciated topic because it helps people plan ahead and feel confident about what's coming next. Understanding detection windows can reduce stress and empower better decision-making.
On average, THC—the active compound in cannabis—can be detectable in urine for 3 to 30 days. Casual users might clear it within a few days, while frequent or heavy users could remain positive for up to a month or longer. Blood tests typically detect THC for only 1–2 days, saliva tests for about 1–3 days, and hair tests can reveal use going back up to 90 days.
Several factors influence how fast THC leaves your body, including metabolism, body fat percentage, frequency of use, and overall hydration levels. People with higher body fat tend to retain THC longer because the compound is lipophilic, meaning it binds to fat cells. Compounding this, someone who smokes daily will naturally take longer to test clean than an occasional user.
