Learn about the different drug tests, detection timeframes, and more.
The threshold set for a "positive" result varies depending on the type of test, and each method has its own detection timeframes.
Hair follicle drug tests can detect THC and its metabolites after 5 to 7 days of consuming cannabis.
The most commonly cited detection time for marijuana in hair is 90 days, although this timeframe is calculated based on various factors.
Urine tests are commonly used for drug screening and can detect THC as soon as 2-24 hours after use and up to several weeks.
Saliva tests are another method for detecting THC, and the detection window is typically within 2-72 hours after use.
Blood tests can also identify THC and its metabolites, with detection occurring as soon as a few hours after consumption and lasting up to a week.
Cannabis-based products that don't come from marijuana may still contain THC and can affect drug test results.
Delta-8 THC, a hemp-derived cannabinoid, can also be detected in hair, and the length of detection will depend on various factors.
The accuracy and reliability of drug tests can vary, and false positives or negatives are possible.
It is important to note that drug dealers may have their own theories about how long THC stays in the system, but scientific evidence should be relied upon.
Understanding the different drug tests, their detection timeframes, and the presence of THC and its metabolites can help individuals make informed decisions.
