    The detectability of THC varies widely with individual factors such as metabolism, quantity, and frequency of use. Typically, it can be detected for up to 3 days after a single use, up to 10 days with moderate use, and up to 30 days or more with heavy use, depending on the type of test.

  • Can an employee test positive for marijuana (THC) if they have been exposed to secondhand cannabis smoke?

    It is highly unlikely for an employee to test positive for THC as a result of secondhand smoke exposure, assuming it occurs under normal environmental conditions without prolonged, intense exposure in an unventilated space.

  • What should employers do if an employee's prescription medication results in a positive THC test?

    Suppose an employee's prescription medication leads to a positive THC test. In that case, employers should verify the prescription with appropriate documentation, consider reasonable accommodations, and consult legal guidelines and their drug policy to ensure compliance and fairness.
