Pre-Employment Drug Testing Laws by State

Compliance

Election Day brought several important changes to medical and recreational marijuana laws. Arizona, Montana, New Jersey and South Dakota now allow usage for both medical and recreational purposes, while Mississippi voted to legalize medical marijuana.

As we enter 2021, with other states also considering new legislation, Paycor will keep this updated with any further changes to help you stay compliant.

With so many states (34 at last count) legalizing medical and/or recreational marijuana, the pros and cons of drug or alcohol testing job applicants has become something of a hot topic. Marijuana accounts for nearly half of all positive drug test results.

The question that you might be grappling with is: Do I really want to limit my talent pools by requiring that every prospective employee be tested? Because you can’t pick and choose; if you have a drug testing policy, it has to apply to all applicants, not just a select few. Check out our table for a high-level overview of state laws for applicant drug testing.

Federal Drug Testing Laws

Job applicants or employees in positions such as airline pilots, bus drivers, railroad employees, taxi drivers, and truck drivers are regulated by the Department of Transportation and must comply with federal laws, which require applicants to take and pass a pre-employment urine test. If a person in one of these positions is ever in an accident on the job, they will also be required to take a post-accident drug test.

The Department of Defense (DOD) created drug testing laws for contractors who work in positions responsible for national security, Drug-Free Workplace, 42 Code of Federal Regulations (CFR) 223.5. To comply with the rules, every DOD contractor who has any type of security clearance or access to classified information must have a drug-free workplace policy that includes:

An employee assistance plan (EAP) that coordinates with local resources such as a drug rehab facility
A stipulation that an employee can self-refer and that supervisors also can refer for drug abuse treatment
Training for supervisors to help them understand how to detect and respond to illegal drug use
A formal and supervised employee drug testing policy

DOD rules also require contractors to confirm that drug testing policies are in compliance with applicable state’s laws and also ensure that all labor unions have agreed to the policies.

With a few exceptions (e.g., companies that are awarded federal contracts), private businesses aren’t mandated to test job applicants who make it to the hiring stage, but many do because they receive a discount on their Workers’ Compensation Insurance.

The “Just Say No” Era

The majority of today’s drug testing mindset dates back to the Reagan administration, when many companies implemented “drug-free workplace” policies under the United States government’s Drug-Free Workplace Act of 1988. The act essentially says that any company that gets federal contracts or grants must be a drug-free workplace, or it could lose its federal funding. Pre-employment testing is a key part of the policy.

There’s no question that alcohol and drug use among certain professions can be a dangerous proposition. It can affect judgment and concentration and may put companies at risk for a lawsuit. The National Council on Alcoholism and Drug Dependence estimates that employee use of drugs and alcohol has resulted in annual losses of $81 billion. According to Executive Order 12564, federal employees who are involved in national security, law enforcement, protecting life and property, and public health are subject to mandatory drug testing.

Of course, state laws vary when it comes to conducting a test for drugs or alcohol in the workplace or as a pre-employment screening (which is why we created our easy-reference table).

Types of Drug Tests

Drug testing is typically conducted prior to tendering an offer of employment. A failed drug test could result in the job offer being withdrawn. Pre-employment drug tests typically scan for six substances:

Amphetamines (speed, crank, meth)
Ecstasy
THC (marijuana, hash)
Cocaine (crack)
Opiates (codeine, morphine, heroin)
PCP (angel dust)

Pre-employment Drug Tests and the Constitution

An employer’s test typically doesn’t violate an applicant’s rights, but the way the test was carried out (or how its results are used) can sometimes be a bit of a gray area. The U.S. Supreme Court has ruled that wholesale drug tests with no specific motivation for suspicion are unconstitutional. They also ruled that the results of an applicant or employee testing positive can’t be used in future criminal cases without the person’s consent. And a test can be challenged on constitutional grounds if the results are indiscriminately revealed or if testing is excessive or otherwise inappropriate. So, it’s easy to see why many employers are abandoning applicant drug testing altogether.
