A compliant multi-state program begins by defining who qualifies as an examinee and what constitutes a controlled substance examination, as outlined in North Carolina law.
How to structure a compliant multi state drug testing program
To build a testing program that holds up across jurisdictions, you must first anchor your definitions to the specific statutory language of each state where you operate. The North Carolina General Assembly defines a "Controlled substance examination" as all actions related to drug testing for the purpose of determining if an examinee has used controlled substances, according to North Carolina General Assembly. This definition sets the boundary for what your testing protocol actually covers; it is not just the lab result but the entire process of determining usage.
Your next step is to identify who legally counts as the "Examiner." The North Carolina General Assembly specifies that an Examiner is a person, firm, or corporation doing business in the State, including State, county, and municipal employers, who is the employer or prospective employer of the examinee and who performs or has performed by an approved laboratory a controlled substance examination, according to North Carolina General Assembly. This means your company entity must be the one directing the test, and the test must be executed by a laboratory that meets the state's approval standards.
Equally important is defining the "Examinee." The North Carolina General Assembly states that an Examinee is an individual who is an employee of the examiner or an applicant for employment with the examiner and who is requested or required by an examiner to submit to a controlled substance examination, according to North Carolina General Assembly. This limits your testing authority to current employees and job applicants. You cannot extend this definition to contractors, interns, or other non-employee personnel unless your specific state law explicitly includes them.
Key takeaways for how to set up a compliant drug testing program for employees
- Confirm that your program’s actions comply with the applicable subchapter, adopted rules, and the employer’s written policy approved under section 686, as required by Maine Legislature.
- Send any sample with a non-negative test result to a qualified testing laboratory for confirmation testing, according to Maine Legislature.
- Ensure the testing laboratory sends test reports for segregated samples to both the employer and the employee or applicant tested, according to Maine Legislature.
- Track the 5-day window after notice of the test result, during which the employee or applicant must notify the employer of the testing laboratory they selected, as stated by Maine Legislature.
- Verify that your written policy addresses these specific procedural steps to maintain compliance with the testing procedures outlined in Title 26, §683.

Verify that your current laboratory contracts and internal protocols align with the specific retention and accreditation criteria listed in the rows above before finalizing your multi-state policy.
Defining the scope and eligibility of your testing program
Start by identifying who qualifies as an "examinee" under your specific jurisdiction. According to the North Carolina General Assembly, an examinee is an individual who is an employee of the examiner or an applicant for employment with the examiner and who is requested or required by an examiner to submit to a controlled substance examination. This definition establishes the baseline population for your testing program. The same source defines the "examiner" as a person, firm, or corporation doing business in the State, including State, county, and municipal employers, who is the employer or prospective employer of the examinee and who performs or has performed by an approved laboratory a controlled substance examination. You must verify that your organization fits this definition before initiating any testing procedures.
The term "controlled substance examination" itself is defined by the North Carolina General Assembly as all actions related to drug testing for the purpose of determining if an examinee has used controlled substances. Keep this scope in mind when drafting internal protocols to ensure they align with the statutory definition of the examination process.
Eligibility limits vary significantly by state. In Minnesota, the Minnesota Revisor of Statutes states that an employer may not request or require an employee or job applicant to undergo drug and alcohol testing except as authorized in this section. This creates a strict boundary for when testing is permissible. For pre-employment scenarios, the Minnesota Revisor of Statutes allows an employer to request or require a job applicant to undergo drug and alcohol testing provided a job offer has been made to the applicant and the same test is requested or required of all job applicants conditionally offered employment for that position.
Selecting approved laboratories and confirming positive results
Verify that your testing vendor meets specific accreditation criteria before processing any samples. The North Carolina General Assembly defines an "Approved laboratory" in G.S. 95-231 as a clinical chemistry laboratory which performs controlled substances testing. This facility must have demonstrated satisfactory performance in the forensic urine drug testing programs of the United States Department of Health and Human Services or the College of American Pathologists for the type of tests and controlled substances being evaluated, according to North Carolina General Assembly. Confirm your lab’s certification status matches these specific program requirements for every substance you intend to screen.
When a screening result comes back non-negative, the sample must be sent to a qualified testing laboratory for confirmation testing. Do not treat a single screening result as final; the statutory language mandates a secondary confirmation step through a qualified facility to validate the initial finding.
For employers operating in Minnesota, specific safeguards apply to cannabis testing. The Minnesota Revisor of Statutes notes in Sec. 181.951 that cannabis testing authorized under this section must comply with the safeguards for testing employees provided in sections 181.953 and 181.954, according to Minnesota Revisor of Statutes.
Additionally, the Minnesota Revisor of Statutes specifies limits on when cannabis testing can be requested. An employer must not request or require a job applicant to undergo cannabis testing as a condition of employment unless otherwise required by state or federal law, according to Minnesota Revisor of Statutes. This restriction applies specifically to the pre-employment phase and is contingent on other legal requirements. Review your vendor contracts to ensure they align with these state-specific confirmation and safeguard protocols.
Handling sample collection, retention, and release
Sample handling rules vary by state, so your program must track which jurisdiction’s statute governs each employee. The following requirements apply specifically to the states named in the source documents.
In Maine, if an employee or applicant requests that their sample be segregated, the testing laboratory has a specific reporting duty. The laboratory must send test reports for those segregated samples to both the employer and the employee or applicant who was tested, according to Maine Legislature. This rule ensures that when a sample is set aside at the individual’s request, the results are not sent solely to the employer but are also provided directly to the person tested.
Maine also imposes a notification deadline on the employee or applicant regarding secondary testing. Within 5 days after notice of the test result is given to the employee or applicant, the individual must notify the employer of the testing laboratory selected by the employee or applicant, according to Maine Legislature. Your HR team should track this 5-day window to ensure the employer is informed of the chosen lab in a timely manner, as the statute places this notification obligation on the employee or applicant rather than the employer.
North Carolina has a distinct retention requirement for confirmed positive results. A portion of every sample that produces a confirmed positive examination result must be preserved by the laboratory that conducts the confirmatory examination, according to North Carolina General Assembly. The preservation period is at least 90 days from the time the results of the confirmed positive examination are mailed or otherwise delivered to the examiner, according to North Carolina General Assembly. This rule applies specifically to samples that yield a confirmed positive result, not to all collected samples, and the clock starts when the results are delivered to the examiner, not when the sample is collected.
Drafting and approving the written testing policy
The written policy is the operational backbone of your compliance framework. According to the Maine Legislature, all actions taken under a substance use testing program must comply with the subchapter, rules adopted under the subchapter, and the employer's written policy approved under section 686. This requirement ties every procedural step back to a single, approved document. Before you establish any substance use testing program for employees, the Maine Legislature requires that an employer with over 20 full-time employees must have a functioning employee assistance program. This precondition ensures that support structures exist before testing begins.
Notification rules vary by applicant status. If an employer intends to test an applicant, the Maine Legislature mandates that the employer shall provide the applicant with a copy of the written policy under subsection 2 before administering a substance use test to the applicant. This pre-test disclosure protects the applicant's right to understand the program's terms. In Minnesota, the Minnesota Revisor of Statutes specifies that if the job offer is withdrawn, as provided in section 181.953, subdivision 11, the employer shall inform the job applicant of the reason for its action. This requirement applies specifically when the withdrawal is tied to the testing process outlined in the statute.
Hiring restrictions also shape the policy's scope. According to the Minnesota Revisor of Statutes, unless otherwise required by state or federal law, an employer must not refuse to hire a job applicant solely because the job applicant submits to a cannabis test or a drug and alcohol test authorized by this section and the results of the test indicate the presence of cannabis. This rule limits the grounds for rejection based on positive cannabis results in the absence of other legal mandates.
