4 Types of Drug Tests

1. PRE-EMPLOYMENT
Screening is typically done after a conditional job offer is made but before a new hire starts working.

2. POST-ACCIDENT
Testing is required after an incident—such as an accident that caused fatalities or injuries—to determine whether drug use could have contributed.

3.  RANDOM
Employees are selected at random from all the participants in a drug-free-workplace program for unannounced testing.

4.  REASONABLE SUSPICION
Workers are tested when they show signs of intoxication, such as slurred speech and uncoordinated movements.
