Maine Employee Drug Testing Policies Affected By Recreational Marijuana Law

Maine Employees Can't Be Fired for Using Marijuana Outside of WorkReminder to Maine employers! Starting February 1, 2018, employees and applicants aged 21 and over are protected from discrimination on the basis of their marijuana usage outside of the workplace. Under state law, employers cannot refuse to employ a person “solely” on the basis of their “consuming marijuana outside of the… employer’s… property.” Schools and landlords are similarly prohibited from discriminating against an individual based on their use of marijuana outside of the school’s or landlord’s property.

Maine’s recreational marijuana law was approved by voters during the 2016 general election, along with a measure to increase the state’s minimum wage. The law allows for the “possession and use of marijuana by a person 21 years of age or older,” and also provides for a retail structure for recreational marijuana, including licensure of facilities for cultivation, testing, manufacturing, and sale of marijuana products. The state has not yet passed the necessary regulations to allow for the retail sale of marijuana, but provisions covering personal use, possession, and cultivation went into effect last year.

Maine is the eighth state to legalize recreational marijuana sales, but the first to explicitly prohibit employers from firing or refusing to hire a person due to their off-site recreational marijuana use. The law does specify that the anti-discrimination provision “does not affect the ability of employers to enact and enforce workplace policies restricting the use of marijuana by employees or to discipline employees who are under the influence of marijuana in the workplace.”

Proving that an employee was under the influence while working will, however, become more difficult. Unlike many other substances which are flushed out of an individual’s body relatively soon after use, such as alcohol, marijuana can remain in a person’s system for days or even weeks after it was consumed. As such, a Maine Department of Labor (MDOL) spokesperson confirmed to lawmakers last year that, under the current law, a drug test which confirms the employee’s use of marijuana alone will not be considered sufficient proof that the employee was under the influence while working.

Employers who wish to enact a drug testing program are required to gain policy approval from MDOL, and the agency provides policy guidance here. Employers with questions about testing policies under the new law should consult with MDOL or with the Maine Department of Agriculture, which enforces the recreational marijuana law.

State Senator Amy Volk introduced a bill in late January which would loosen current restrictions on employer drug testing policies, including removing probable-cause requirements. While the proposal has the support of MDOL, a representative from the Maine Human Rights Commission raised concerns that the bill could open employers up to claims of discrimination from employees with disabilities who exhibit behaviors resembling impairment, or potentially violate the Maine Human Rights Act.

CPC will continue to follow this bill as it moves out of committee and through the legislature, as well as all other laws and regulations which may affect employer rights and responsibilities in Maine.

  1. Where is the legal proof of this? Ive checked the maine dept of labor list, and marijuana is still on the drug test list. Also, my employer has made no changes to our drug testing policy. What do i need to know, and what legal documents or laws protect the employees


    1. Hi, Chris. You can read Maine’s statutes governing substance abuse testing here and the non-discrimination provisions of the Marijuana Legalization Act are here. The Act does not prohibit drug testing employees for the use of marijuana, although it does prohibit employers from refusing to employ an individual solely on the basis of their consumption of marijuana outside of the employer’s property.

      Some employees are also covered by federal laws which allow employers to exert more control over employees’ off-site consumption of substances, either because the employee is a federal employee or employed by a federal contractor, or because the employee’s job poses significant risks to the safety and health of the employee, their coworkers, and/or the public. You can find more information about federal laws here.


  2. If an employer has employees, some of whom are subject to stricter DOT drug testing rules, and employees not subject to DOT rules, can the employer NOT hire an employee who will not be subject to DOT drug testing rules solely based on a positive pre-employment marijuana test.


    1. Hello, Kelly. The Maine Department of Labor states the following on its Substance Abuse Testing page: “If an employer has any employees who are subject to a federally mandated drug-and-alcohol testing program working in Maine, that employer may expand the federal testing pool to cover all employees and forego a policy with the State.” However, this message only refers to the state requirement that employers gain state approval for their substance abuse testing programs. The recreational marijuana law is a separate law with a separate enforcement policy.

      Unfortunately, we are unable to provide legal advice on this or any matter. You should contact the Maine Department of Labor and/or the Maine Department of Agriculture (which enforces most provisions of the recreational marijuana law) for guidance.
