Maine Drug Testing Laws for Employers

Approval Before Testing

26 M.R.S. 683 opens with the operative rule: an employer may not require, request or suggest that any employee or applicant submit to a substance use test except in compliance with the section, and all actions taken under a testing program must comply with the subchapter, its rules, and the employer's written policy approved under section 686.

The policy has to provide, at minimum, for: the procedure and consequences of voluntary admission of a substance use problem and the assistance available; when testing may occur, including which positions are testable and the selection procedure for any random testing; sample collection; sample storage; chain of custody; the substances tested for; cutoff levels for screening and confirmation; the consequences of a confirmed positive; the consequences of refusal; rehabilitation opportunities and procedures after a confirmed positive; and an appeal procedure that costs the appellant nothing.

You must consult your employees in developing any portion that applies to employees. Then the policy goes to the Department of Labor, which reviews it for compliance, notifies you immediately of its determination, and identifies the specific defective areas if it does not comply. The department is expressly barred from approving any policy providing for random testing of a position the employer has not demonstrated qualifies. Employees get notice of a submitted policy and an opportunity to file written comments challenging any part of it.

The Thresholds That Decide What You Can Do

Maine attaches specific headcounts to specific obligations, and they do not all use the same number:

• More than 20 full-time employees: you must have a functioning employee assistance program before establishing any employee testing program. A cooperative multi-employer EAP satisfies this.
• 50 or more employees not covered by a collective bargaining agreement: the threshold for an all-employee random program.
• At least 10 employees on the committee that writes the policy for that random program, including a trained medical professional — hired in if you have none on staff.
• More than 20 full-time employees: you split rehabilitation costs equally with the employee.

The random-testing machinery deserves emphasis because it inverts the normal power relationship. The committee writes the policy, the department approves it, and the employer may not change it without the committee's approval. You also may not retaliate against an employee for participating, or for refusing to participate, in that committee.

Three Mechanics a National Program Will Miss

1. A cannabis cutoff floor. Section 683(2)(G)(1) provides that confirmation cutoffs for cannabis may not be lower than 15 nanograms of THC-COOH per milliliter for urine. As in Louisiana, tightening your cutoff is not your call here.
2. The employee can take urine off the table. Under 683(5)(B), an employee — not an applicant — may demand at the time of collection that a blood sample be drawn and tested for alcohol or cannabis metabolites, and if they do, no other sample may be tested for those substances. Your urine result for those analytes simply does not exist.
3. The law follows people out of state. Section 681(5) requires Maine employment contracts to include an agreement extending the subchapter to employees hired to work outside Maine.

Probable Cause Is Defined, and Narrow

Maine does not use "reasonable suspicion." Section 682(6) defines probable cause, and section 684(2) restricts who may determine it: the immediate supervisor, other supervisory personnel, a licensed physician or nurse, or security personnel — who must state the facts in writing and give the employee a copy.

Three things expressly cannot carry it on their own: an anonymous informant, off-duty possession or use, and a single work-related accident. That last exclusion is the one to note, because it removes the most common post-accident trigger used elsewhere.

Collection, Laboratory and Results

• No observation at all. No direct or indirect observation of urine collection and no removal of clothing, with narrow exceptions. Collection must occur in a medical facility supervised by a licensed physician or nurse.
• You may not test your own employees. All employee testing goes to a qualified laboratory with NIDA, CAP or AACC proficiency performance. You may screen applicants in your own facility only if it meets the statute's laboratory requirements.
• Instant devices, applicants only. An FDA-approved noninstrumented point-of-collection device may be used on an applicant's urine or saliva. Negatives are destroyed, positives go to a qualified laboratory, and the result may not be released to the employer until confirmation is determined.
• No numbers. Results may not be reported in numerical or quantitative form without consent, and unconfirmed positive screens for employees must be structurally invisible to the employer.
• Split sample. At collection the person may have a portion segregated, then has five days after notice of the result to name their own laboratory.
• Three working days after notice of a confirmed positive to submit information explaining or contesting it.
• Return-to-work retesting is permitted only between 90 days and one year after the prior test.
• An annual statistical report of all tests, broken out for employees, applicants and random tests, goes to the Department of Labor.

You Cannot Fire on a First Positive

Before any adverse action following an employee's first confirmed positive, the employer must offer up to six months in a rehabilitation program, and split public or private rehabilitation costs equally with the employee where it has more than 20 full-time employees. Pay and benefits may not be reduced while the employee participates, and reinstatement rights attach on successful completion.

What It Costs to Get Wrong

Section 689 provides for three times lost wages, reinstatement with full benefits, court costs and attorney's fees. On top of that sit civil penalties payable to the employee — $1,000 for confidentiality breaches and $2,000 where an employer without substantial justification repeatedly requires an employee to submit to testing. Test results may not be used in any criminal proceeding.

Cannabis, and One Dead Citation

Two live provisions. Under 22 M.R.S. 2430-C(3), an employer may not refuse to employ or otherwise penalize a person solely for that person's status as a qualifying patient or caregiver, unless doing otherwise would violate federal law or cost a federal contract or funding. That is written around status, not around a test result. Under 28-B M.R.S. 112, an employer need not permit or accommodate cannabis in the workplace, may enforce policies restricting use in the workplace or within the course and scope of employment, and may discipline employees under the influence there. Section 112 contains no off-duty protection.

Watch for a dead citation. The predecessor provision at 7 M.R.S. 2454 was repealed outright by PL 2017, c. 409. Guidance still citing it for a Maine off-duty cannabis hiring protection is citing a section that no longer exists.

Whether the status protection or the Maine Human Rights Act reaches a positive cannabis result for a qualifying patient turns on case law rather than statutory text. It is unsettled, and it should go to employment counsel before any adverse action.

Who Is Exempt

Section 681(8) exempts nuclear electrical generating facilities and their employees, and exempts any employer subject to a federally mandated testing program — expressly including the Omnibus Transportation Employee Testing Act of 1991 — along with that employer's employees, independent contractors and contractors' employees. Section 681(4) preempts municipal authority over employer testing.

We found no workers' compensation premium credit and no intoxication-based benefit-denial provision in 39-A M.R.S. 201. That is an unverifiable negative rather than a confirmed absence, so treat it as something to check with counsel rather than a settled fact.

Where This Lands

Maine's employment base runs through healthcare, tourism and food service, forest products and paper, commercial fishing and aquaculture, shipbuilding and defense manufacturing, and food and beverage processing. Shipbuilding and paper both carry genuinely safety-sensitive work — and both will find that the narrowly-construed instruction attached to the safety-sensitive random route means the demonstration has to be made position by position, to the state's satisfaction, before a single random test happens.
