What Kind of Drug Test Detects Cannabis?
Urine Drug Tests
Urine drug tests are the most common method used to detect cannabis. They can identify the presence of THC (the psychoactive component of cannabis) and its metabolites in the body. This type of test is typically reliable for detecting cannabis use up to 30 days after the last ingestion.

Other Types of Tests
- Saliva tests are less common and can detect recent cannabis use, usually up to 24 hours after ingestion.
- Hair follicle tests can detect cannabis use over a longer period, up to 90 days, but are less commonly used for this purpose.
How it Works
Cannabis use leaves behind trace amounts of THC and its metabolites in the body. These substances are detectable through various bodily fluids, including urine, saliva, and hair. Urine tests are favored due to their simplicity and the ease of collection.
