Hiring can be contingent upon passing pre-employment drug and alcohol tests and screenings. Drug testing laws vary by state. In some cases, the law requires drug testing. For example, industries regulated by the U.S. Department are covered by federal or state drug testing requirements. In some states, there are limits to when and how drug screening can be conducted.
Breath alcohol testing devices, commonly known by the term for one type of device - Breathalyzer, measure how much alcohol is currently in the blood. Blood alcohol tests show current levels of impairment or intoxication not past use.

A blood drug test may be used when job applicants or employees are screened for illegal drugs. A blood test measures alcohol or drugs in the blood at the time the blood is drawn. Drugs that are screened for in a typical blood test for employment purposes include amphetamines, cocaine, marijuana, methamphetamines, opiates, nicotine, and alcohol.
A hair drug test provides a 90 day window of drug use. It doesn’t indicate current impairment due to drugs, only past use. A hair drug test does not detect alcohol use. Hair can be tested for cocaine, marijuana, opiates, methamphetamine, and phencyclidine.

A mouth swab drug test, also known as a saliva test or oral fluids test, collects saliva from inside the job applicant or employee's mouth. The saliva is tested for use of drugs during the previous few hours up to one to two days. Saliva is easy to collect and test, so this is the simplest and least invasive type of drug testing.
