Drug Testing

Employee drug testing programs improve workplace production and moral while reducing workplace accidents and costs.

Drug testing has also been shown to drastically reduce drug use when an effective program is developed (Houston Drug Free Business Initiative, University of Houston).

Henderson Consulting & EAP Services offers the following drug testing services:

  • Random selection
  • Pre-Employment
  • Post-Accident
  • Reasonable Suspicion
  • Return-to-duty
  • Follow up

Henderson Consulting & EAP Services contracts with collection sites that possess all necessary materials, equipment and facilities to provide for the collection and refrigerated storage of specimens. By contracting with collection sites, employers have more options regarding testing after hours and/or urgent care.

DOT Regulations require 5-panel testing for the following classes of substances:

  • Marijuana
  • Cocaine
  • Opiates – opium and codeine derivatives
  • Amphetamines and methamphetamines
  • Phencyclidine – PCP


Alcohol Testing

DOT regulations state that a blood alcohol level of .04 is considered positive for alcohol use. This level indicates that the employee has consumed alcohol within 4 hours of beginning their job. DOT regulations also require an employee with a blood alcohol reading of .02-.039 to be sent home. Alcohol testing can be administered randomly before, during, and/or after work hours.

Henderson Consulting & EAP Services contracts with personnel that are certified Breath Alcohol Technicians and have instrumentation to conduct breath alcohol tests.

What will happen to me if I violate a DOT drug & alcohol rule (e.g. test positive, or refuse a test)?

  • Your employer is required to immediately remove you from performing your job duties. You will not be permitted to return until you have:
    • a. Undergone an evaluation by a Substance Abuse Professional (SAP).
    • b. Successfully completed any course, counseling or treatment prescribed by the SAP prior to returning to service;
    • c. Undergone a follow up evaluation by the same SAP to determine your compliance with their recommendations; AND
    • d. Provided a breath and/or urine specimen that tests negative for drugs and/or alcohol prior to returning to DOT regulated safety-sensitive functions.
    • e. You will also be subject to unannounced “Follow-Up” testing for drugs and/or alcohol for at least 6 times during the first 12 months of active service with the possibility of unannounced testing for up to 60 months (as prescribed by the SAP).  The Return-to-Duty and Follow-Up drug tests will be conducted under direct observation.
