State lawmakers have been very busy tackling cannabis issues in 2023, and the year is not over. As of this publication, the adult use of cannabis is permitted in 23 states. Thirty-seven states have authorized the medical use of cannabis.
A clear trend from recent cannabis laws brings employer limitations that we’ve never seen before.
Adding to existing employer limitations surrounding medical marijuana laws, states, and municipalities are now implementing statutes that limit or prohibit employers from screening for cannabis (specifically non-psychoactive cannabis metabolites) or taking adverse employment actions against employees or applicants based on ‘impairment’ or an individual’s lawful, off-duty cannabis use.
These new legislative changes bring a unique complexity to employers’ workplace drug testing program, as they are being enacted before there is reasonable access to new cannabis screening solutions to comply with the language of the laws.
No test or methodology is available today to determine the impairment of cannabis. Furthermore, standard drug testing for cannabis includes non-impairing metabolites.
Another challenge for employers is how the language of the laws in each state (or municipality) differs. Below is a review of the most recent legal changes to workplace drug and alcohol screening programs.
On a positive note, when the companion pieces of legislation, House Bill 1 (HB 1) & House Bill 2 (HB 2), passed in April 2023, they added nothing new to employment screening limitations.
Employers are already limited under the State’s medical marijuana law. In 2011, The Delaware Medical Marijuana Act was passed and signed into law. Employers in Delaware “may not discriminate against a person in hiring, termination, or any term or condition of employment, or otherwise penalize a person, if the discrimination is based upon either of the following:”
(a) The person’s status as a cardholder; or
(b) A registered qualifying patient’s positive drug test for marijuana components or metabolites, unless the patient used, possessed, or was impaired by marijuana on the premises of the place of employment or during the hours of employment.”
Adult-Use of Cannabis Authorized in 23 States
Lawmakers in Minnesota should get an award (kidding) for constructing the most complicated legislation this year so far. In May of 2023, the new adult-use of cannabis law, Senate Bill 73 (SF 73), was passed and took effect on August 1st, 2023.
SF 73 consolidates the existing medical cannabis law with the new adult-use authorization and all other cannabis matters under the authority of the Office of Cannabis Management with the guidance of the Cannabis Advisory Council.
In the process, provisions of the state’s drug testing statute were also amended, and new requirements were added—a complicated list of revisions.
The new law authorizes adult use (21 years old or older) of cannabis. It revises the law, clarifying that employers may not discriminate against off-duty, off-premises use of “lawful consumable products,” including cannabis.
Employers are not required to permit or accommodate cannabis or cannabis product use, possession, impairment, sale, or transfer while an employee is working or while an employee is on the employer’s premises or operating the employer’s vehicle, machinery, or equipment.
However, an employer may only enact and enforce written work rules prohibiting “cannabis flower and cannabis product use, possession, impairment, sale, or transfer, etc., while an employee is working or while an employee is on the company’s premises or operating the company’s vehicle, machinery, or equipment in a written policy.”

Additionally, the law amends numerous sections of the Minnesota Drug and Alcohol Testing in the Workplace Act. It’s important to note that the law redefines the term “drug” removing marijuana, cannabis, or cannabis products. Drug testing no longer includes cannabis, but a new “Cannabis test” definition has been provided. Some key provisions of the new law are as follows:
There are exceptions to the cannabis testing limitations under S.F. 73. A newly added subdivision 9, under section 181.951, provides the following:

Back in 2014, SF 2470 authorized the medical use of cannabis, further limiting employer action. In 2022, Hemp-derived consumables (edibles, etc.) were legalized for adult use.
Employers will notice that SF 73 makes minimal edits to the existing medical use of cannabis law in Minnesota.
However, employers must be careful because the medical use of cannabis law in Minnesota severely restricts employer action related to anti-discrimination protections for medical cannabis users. The relevant sections of the law are as follows:
(c) Unless a failure to do so would violate federal law or regulations or cause an employer to lose a monetary or licensing-related benefit under federal law or regulations, an employer may not discriminate against a person in hiring, termination, or any term or condition of employment, or otherwise penalize a person, if the discrimination is based upon either of the following:
Note: The impact of subdivision 3(d) is not yet known. If an employee is a qualified patient in the state’s medical cannabis program and tests positive for marijuana, subdivision 3(d) says verifying enrollment in the patient registry “may explain the result.” Does that mean the result would be treated as any other medical explanation (e.g., prescription) and reported to the employer as a negative?
This new adult use of cannabis law, combined with the medical use of cannabis law, adds to a complex patchwork of rules affecting workplace drug testing in Minnesota that employers must follow.
Since 1987, a detailed mandatory drug & alcohol testing law has limited who, what, when, where, why, and how an employer conducts testing, and what disciplines can be imposed.
For example, employers must have a written policy. Notice of the employer’s policy must be provided to all those affected, and employers must post notice of the policy in appropriate and conspicuous locations on the employer’s premises.
Employers are also prohibited from terminating an individual after testing positive for the first time – they must be offered an opportunity for treatment, among many other rules.
Medical Use of Cannabis Authorized in 37 States
On Sept. 18, 2022, Governor Newsom signed AB 2188. This new law limits employer action regarding job applicants and current employees based on cannabis test results.[6]
Beginning January 1, 2024, it will be unlawful for any employer[7] to discriminate against a person “in hiring, termination, or any term or condition of employment, or otherwise penalizing a person, if the discrimination is based upon any of the following:
Employees are not permitted to possess, use, or be impaired from the use of cannabis on the job or to affect the right or obligation of their employer to maintain a drug-free workplace or any obligations the employer has under federal rules.
Those in the building and construction trades, jobs regulated under federal law, grants, or contracts are exempt from this new law.

Washington voters approved the medical use of marijuana back in 1998. Then, in 2012, the use of marijuana was authorized for anyone 21 years old or older.
Neither of these two laws has any negative impact on the workplace.[8] However, on May 9, 2023, Washington’s Governor approved SB 5123, protecting an individual’s lawful off-duty use of cannabis[9].
Beginning January 1, 2024, it will be unlawful for an employer to discriminate against a person in the initial hiring for employment if the discrimination is based upon:
But the law goes on to provide . . .
“Nothing in this section:
This section does not apply to an applicant seeking:
Unlike California’s off-duty protections, which apply to all job applicants and current employees, SB 5123 in Washington only applies to job applicants (pre-employment testing).
Federally regulated positions, federally funded projects, and federal contractors are exempt from the new law. Employers may require an applicant to be tested for a spectrum of controlled substances (including non-psychoactive cannabis metabolites) as long as the cannabis results are not provided to the employer.
