What is THC testing?

THC testing refers to the process of detecting and measuring the presence and concentration of tetrahydrocannabinol (THC) in a sample, such as urine, blood, saliva, or a cannabis product. THC is the primary psychoactive compound in cannabis, and testing is commonly used for workplace drug screenings, legal compliance, or quality control in cannabis products. The methods for THC testing can vary, but typically include immunoassays for initial screening and more precise techniques like gas chromatography-mass spectrometry (GC-MS) for confirmation.
