Does Secondhand Smoke Fail a Drug Test?
No, secondhand smoke typically does not cause a positive result on a drug test for THC. However, individual factors and testing methods can affect results.
Introduction
Secondhand marijuana smoke can potentially lead to positive drug test results. It is important to understand the cut off levels for such tests to interpret the results accurately.
What are Cut Off Levels?
Drug test cut off levels refer to the amount of a substance that must be detected in a sample to yield a positive result. For secondhand marijuana smoke, these levels can vary depending on the test.

Factors Influencing Cut Off Levels
- Concentration of THC in the air: Higher concentrations can lead to higher cut off levels.
- Duration of exposure: Prolonged exposure to secondhand smoke can increase the likelihood of detecting THC in a drug test.
- Method of testing: Different types of tests have different cut off levels.
Standard Cut Off Levels
Standard cut off levels for detecting secondhand marijuana smoke in drug tests typically range from 50ng/mL to 200ng/mL.
