Drug tests are administered most often for employment screening. The most common form of drug test is a urine test or urinalysis. These tests will show positive for recreational drugs such as marijuana, ecstasy and cocaine as well as prescription drugs like OxyContin or Xanax. Testing positive for a prescription drug will require a doctor’s confirmation of prescription. Testing positive on a pre-employment drug test may give cause to be denied employment. Testing positive on a post-employment drug test may give cause to terminate employment. There are products on the market that claim to clean or flush one’s system in order to pass a drug test. Regardless of the claims of these products, the only sure way to pass a drug test is to stay clean and not use any drug that would show up on a drug test.
