How to Conduct a Legal Drug Test (Pubic Works Employers)

Step 1 – Since it is required of employers to implement a drug-testing program, it may not be necessary for employees to sign and submit a Drug Test Release Form.

Step 2 – Testing must be performed by a laboratory certified for Federal Workplace Drug Testing Programs by the Substance Abuse and Mental Health Services Administration (SAMHSA). The test shall comprise of a 9 panel urine drug test plus a test for alcohol. Blood can only be tested under a post-accident circumstance. A list of certified labs can be found on the SAMHSA website.

Step 3 – Positive tests will result in the immediate removal of the employee or, concerning applicants, a refusal to hire. The employee can complete a rehabilitation program in order to be reinstated to their former position of employment.
