the Centers for Disease Control and Prevention (CDC) itself does not conduct drug testing on individuals. Drug testing is typically carried out by employers, law enforcement agencies, medical facilities, or other organizations.
The detection window for drugs in urine and blood can vary depending on the specific drug being tested and the frequency and amount of drug use. Generally, urine tests can detect drugs for a few days to a few weeks after use, while blood tests have a shorter detection window of a few hours to a few days.
It's important to note that drug testing procedures and policies may change over time and can differ depending on the jurisdiction or organization conducting the testing. For the most accurate and up-to-date information on drug testing and its detection windows, it's best to refer to the guidelines and protocols established by the specific entity performing the drug tests.
