Drug Testing

Brief Description

Some schools, hospitals, or places of employment conduct drug testing. There are a number of ways this can be done, including: pre-employment testing, random testing, reasonable suspicion/cause testing, post-accident testing, return to duty testing, and follow-up testing. This usually involves collecting urine samples to test for drugs such as marijuana, cocaine, amphetamines, PCP, and opiates. NIDA’s resources include the issues involved with decisions to conduct drug testing.
