Maryland, known for the breathtaking Chesapeake Bay and, as one of the original 13 colonies, it is full of rich American history and miniature topographic scenes scattered throughout its 12,407 square miles. Home to over 6 million residents, Maryland is home to a lively diverse culture. Unfortunately, it is also struggling to fight an epidemic that has touched the entire nation. The uprise in deaths from drug and alcohol use has been on the rise since 2016, with numbers in the thousands. The main culprits being heroin and fentanyl, as they are both cheap and potent. Alcohol has also posed a huge problem in the state and is responsible for a significant amount of admissions into treatment centers across Maryland.

Drug-Free Workplace Programs

Depending on if a drug-free workplace program has been implemented, companies may require pre-employment, reasonable suspicion and post-accident testing. Maryland drug testing laws may provide employment-related protections to an employer when action is taken against an employee who violates the company's drug and alcohol policies.

A drug testing program in Maryland should include the following:

  1. Written Substance Abuse Policy
  2. Supervisor Training
  3. Employee Education and Training
  4. Employee Assistance Program (EAP)

US Drug Test Centers strongly supports comprehensive drug-free workplace programs, especially within companies involving safety-sensitive duties like operating machinery and commercial vehicles. We can help you create a workplace drug-testing policy and provide training to you and your employees.

Regulations like Maryland Occupational Safety and Health (MOSH) require employers with safety-sensitive employees to undergo mandatory drug testing that must meet DOT and Maryland drug testing regulations. The following positions are deemed safety-sensitive: crane operators, signalpersons, riggers, and crane operator trainees. We offer DOT testing and services for individuals and employers. Random consortium programs and and complete owner-operator packages are all available.

Same Day Testing

Same day testing is available for employers and individuals in all areas of Maryland. Call early in the day for same day drug testing. All of our tests can also be ordered with one quick phone call - 1 866-566-0261.

Standard laboratory drug tests provide negative results back in 1 – 2 business days, sometimes specimens have to go on for further testing and results will take 2 – 3 business days longer. Ask about availability for instant drug testing in selected facilities throughout Maryland. For workplace testing, rapid or on-site testing is permitted for pre-employment testing only. For personal or individual drug testing, rapid or on-site testing is permitted.

Maryland drug testing laws allow for the use of hair specimens for pre-employment purposes only. The hair sample must only be one and half inches long from the body and cannot be used for purposes other than for testing for the presence of controlled dangerous substances.

Testing options may vary on a site by site basis. Additional fees may apply depending on your location.
