Can Secondhand THC Smoke Cause a Positive Drug Test?

Secondhand THC smoke can indeed lead to a positive drug test, although it is not a frequent occurrence. The presence of THC in the bloodstream can be detected through urine or saliva tests, and if someone is exposed to secondhand smoke, they may test positive. However, the concentration of THC in the secondhand smoke is typically lower than from direct inhalation, which can affect the test results.
