A standard drug test typically tests for marijuana, cocaine, amphetamines, opiates, and phencyclidine (PCP).

The most commonly used drug test is a urine test, but blood, hair, and saliva tests may also be used.

The length of time that drugs can be detected in your system depends on the type of drug, how it was taken, and other factors. For example, marijuana can be detected in urine for several weeks after use, while cocaine is usually only detectable for a few days.

Yes, certain prescription medications can cause a positive drug test result. It's important to inform your employer or the testing facility if you are taking any prescription medications.

Attempting to cheat on a drug test is not recommended and can lead to serious consequences. Testing facilities have methods in place to prevent cheating, and attempting to cheat may result in a failed test or even legal action.
