A drug test result indicating ‘no THC’ means that tetrahydrocannabinol (THC), the psychoactive compound in cannabis, was not detected at or above the laboratory’s cutoff concentration. This typically indicates that the individual has not recently used cannabis or that THC levels are below the threshold for a positive result. Interpretation depends on the type of test, detection window, and individual factors.
