Maine regulates private employer drug testing more closely than most states. Instead of leaving testing to an employer's own policy, the state built an approval system into the law itself. The rules sit in Title 26, Chapter 7, Subchapter 3 A, cited as 26 MRSA 681 to 690, and they require most employers to get a written testing policy reviewed by the Maine Department of Labor before testing starts. This article covers what that subchapter requires, how the state's cannabis law fits in, and where federal transportation rules take over; for a state comparison, see our post on workplace drug testing laws by state. Section numbers below should be confirmed against the current statute text before an employer adopts a policy.
The purpose clause and employer discretion
Under section 681, the subchapter protects employee and applicant privacy from undue invasion while still allowing testing when an employer has a compelling reason, requires test procedures that produce reliable results, gives an employee with a substance use disorder a path to rehabilitation, and aims to reduce drug use in the workplace. The law does not require any employer to test. An employer that does test is bound by all of it, though it may adopt supplemental policies that are not inconsistent with it. Section 681 also preempts local rules: a municipality may not regulate an employer's use of substance use tests under its own home rule authority.
Section 682 defines the key terms the subchapter relies on, including applicant, employee, employer, negative test result, and positive test result, and it defines a confirmed positive result as a confirmation test result above the cutoff level, not just an initial screen. That distinction between screen and confirmation carries through the rest of the law, since several employer obligations attach only once a result is confirmed.
The written policy and the employee assistance program requirement
Section 683 is the operational core of the statute. An employer may not require, request, or suggest that an employee or applicant submit to a substance use test except in compliance with this section, and every action taken under a testing program must follow the subchapter, its rules, and the employer's own approved written policy. Before establishing any testing program for employees, an employer with more than 20 full time employees must have a functioning employee assistance program, which it may satisfy by participating in a cooperative program serving more than one employer. The policy must describe, at minimum, how an employee can voluntarily disclose a substance use problem and what assistance is available, which positions face testing and how employees are selected for random testing, and how samples are collected, including a requirement that collection happen in a medical facility supervised by a licensed physician or nurse. A compliant process typically pairs an initial screen, such as a multi panel drug test cup, with confirmation at a certified laboratory.
When testing is allowed: applicants, probable cause, and limited random testing
Section 684 sets out the only circumstances in which an employer may require, request, or suggest a substance use test. For applicants, an employer may test only after an offer of employment, or a position on a roster of eligibility, and the offer itself may be conditioned on a negative result; the conditional offer has to come first, then the test. For current employees, an employer may test on a probable cause basis if a supervisor, a licensed physician or nurse, or security personnel determines probable cause exists and puts the supporting facts in writing for the employee.
Random or arbitrary testing of employees is narrower, limited to three paths: a collective bargaining agreement that provides for it, a position where impairment would create what the statute calls an unreasonable threat to health or safety, a standard meant to be narrowly construed, or an employer with 50 or more non union employees that sets up a program through a dedicated employee committee of at least 10 workers, including a trained medical professional, with the policy submitted to the Department of Labor for approval. Employees already covered by a collective bargaining agreement are not swept into that committee path unless they separately agree to it.
| Testing category | What 26 MRSA 684 requires |
|---|---|
| Applicant testing | Only after a conditional offer of employment or a roster of eligibility offer |
| Probable cause testing of employees | Determination by a supervisor, licensed physician or nurse, or security personnel, documented in writing |
| Random testing under a union contract | Must be bargained for in a collective bargaining agreement |
| Random testing for safety sensitive roles | Limited to positions creating an unreasonable threat to health or safety if the employee is impaired |
| Random testing without a union contract | Only for employers with 50 or more non union employees, via an employee committee policy approved by the Department of Labor |
| Department of Labor approval | Required under 26 MRSA 686 before a written policy, including any random testing component, takes effect |
What happens after a test, and the rehabilitation requirement
Section 685 limits what an employer can do with a result. While waiting for results, an employer may suspend an employee with full pay and benefits or transfer the employee with no reduction in pay or benefits. Once a result is confirmed positive, or if someone refuses a properly requested test, an employer may use that as a factor in refusing to hire, discharge, discipline, or reassignment, subject to the Maine Human Rights Act and other law. Before acting against an employee on an initial confirmed positive result, the employer must offer up to six months to participate in a rehabilitation program, and may only act without that offer if a later test is also positive. Rehabilitation costs are split between employer and employee for employers with more than 20 full time employees, except that the statute exempts testing mandated by the federal Omnibus Transportation Employee Testing Act of 1991 from this state cost sharing rule.
Review and approval by the Department of Labor
Section 686 makes the Department of Labor a gatekeeper. It must review every written policy, or change to an approved policy, submitted under section 683, determine whether it complies with the subchapter, and notify the employer of the result, including specific defects if it does not comply. The department may request more information to confirm a position meets the random testing standard under section 684, and may not approve a policy covering a position the employer has not shown meets that standard. Its rules must also allow any federally recognized substance use test and provide for employee notice and written comments before a policy is approved.
Confidentiality, violations, and remedies
Section 689 makes a violating employer liable for triple lost wages, reinstatement, court costs, and attorney's fees. Breach of confidentiality and harassment through repeated or unjustified testing each carry separate civil penalties, up to 1,000 dollars for a first offense and 2,000 dollars for a later offense against the same employee, enforceable by the Department of Labor or the employee. Section 688 separately requires employers to cooperate with state substance use education programs. Employers building a program from scratch can also compare approaches in our related post on how random drug testing selection works.
Cannabis and workplace testing in Maine
Maine legalized adult use cannabis through the Cannabis Legalization Act, codified at Title 28 B. 28-B MRSA 112 states that, except as otherwise provided in the Maine Medical Use of Cannabis Act, an employer is not required to permit or accommodate cannabis use in the workplace, may enact workplace policies restricting cannabis use on the job, and may discipline employees under the influence at work under those policies. On its own terms, section 112 addresses workplace use and impairment, not whether an employer may test for marijuana; testing itself is governed by 26 MRSA 683 and 684, and legalizing cannabis for personal, off duty use did not remove marijuana from the substances an approved policy may include. Because Maine cannabis policy has changed more than once since 2016, do not assume a pre employment marijuana testing restriction is currently in force without checking current statute text and the Department of Labor's guide to marijuana in the workplace. Medical cannabis adds a layer this article cannot resolve; treat a registered patient on staff as a case for counsel.
Federal exceptions for DOT regulated positions
None of the state approval process above replaces federal testing rules for safety sensitive transportation employees. Employers with drivers, mechanics, or other covered workers must still follow the collection, laboratory, and medical review officer procedures in 49 CFR Part 40, and Maine's statute treats that federal program as a distinct track, exempting federally mandated testing from the state cost sharing rule above. A DOT regulated employer should build its program around Part 40 first, then apply Maine's approval requirements to any additional, non federally regulated testing.
Frequently asked questions
Does a Maine employer need government approval before testing employees?
Generally yes. Under 26 MRSA 683 and 686, an employer that wants to run a substance use testing program has to develop a written policy and submit it to the Maine Department of Labor, which reviews it for compliance before the employer may rely on it.
Can a Maine employer test job applicants for drugs?
Yes, but only after the applicant has already received a conditional offer of employment or a position on a roster of eligibility, as set out in 26 MRSA 684. The employer may condition the offer itself on a negative test result.
When can a Maine employer randomly test current employees?
Random or arbitrary testing is limited to three situations under 26 MRSA 684: a collective bargaining agreement that provides for it, a position where impairment would pose an unreasonable safety threat, or an employer with 50 or more non union employees running a program built and approved through a dedicated employee committee.
Does Maine's cannabis law stop employers from testing for marijuana?
28-B MRSA 112 addresses workplace use and impairment, not testing, and does not by itself exempt marijuana from an approved policy. The testing rules come from 26 MRSA 683 and 684; confirm current statute text and Department of Labor guidance before setting a marijuana testing policy.
What does a Maine employer owe an employee after a confirmed positive result?
Before taking action such as discipline or discharge on an employee's first confirmed positive result, 26 MRSA 685 requires the employer to offer up to six months of participation in a rehabilitation program, with certain cost sharing rules depending on employer size, before any further action is allowed.
Do DOT testing rules replace Maine's state law for truck drivers and other safety sensitive workers?
Federal rules in 49 CFR Part 40 control testing for safety sensitive transportation positions, and Maine's statute treats federally mandated testing as a separate track. Employers should follow the federal program for those positions first, then apply Maine's approval requirements to any additional testing outside it.
