How Long Does Cannabis Stay In Your System?

Cannabis Detection Times: What to Know

Understanding how long cannabis can be detected helps people make sense of urine, blood, saliva, and hair testing windows.

Why Times Vary
Detection time is not the same for everyone. Frequent users tend to retain cannabis metabolites longer than occasional users, and body fat, hydration, and metabolism also play a role
.

More frequent or higher-dose use generally means longer detection times.

How Long Tests Can Detect Cannabis
Urine tests are the most common and can detect cannabis metabolites for about 1–3 days in occasional users, up to 7–10 days in moderate users, and 30 days or more in heavy daily users
.

Blood tests usually detect THC products online [http://tracker.onrecruit.net] for a shorter window, often 1–2 days for occasional users and up to about a week for heavy users, though this can vary
.

Saliva testing is often used for very recent exposure.

Hair tests reflect longer-term use patterns rather than recent use.

Why This Matters
Knowing how long cannabis can be detected helps people interpret test results and expectations.

Impairment and detection are not the same thing.
