Will cocain and marijuana show up in a biometric screening?

Cocaine and marijuana can show up in a biometric screening, but it depends on the type of test being conducted. Standard drug tests, such as urine or blood tests, are commonly used to detect these substances. Marijuana can be detected for several days to weeks after use, while cocaine typically has a shorter detection window. Biometrics, which often refer to physiological measurements, do not directly test for drugs; however, if a test includes biochemical analysis, these substances could potentially be identified.
