For New York public school districts, the governing rule is much narrower than “schools may test because they work with children.”

General rule

A New York school district generally may not require a teacher, principal, administrator, clerical employee, custodian, or other ordinary applicant to take a cannabis test simply as a routine condition of hiring.

New York Labor Law §201-d protects lawful, off-duty cannabis use, and the state’s guidance says the protections apply to public employers, including state and local government employers, as well as private employers. The law generally prohibits refusing to hire someone because of lawful cannabis use outside work, off the employer’s premises, and without use of employer property. (Department of Labor)

When a district may test for cannabis

A district may test where an exception applies, principally when:

• a federal or state statute, regulation, or governmental mandate requires testing;

• failing to test would violate federal law;

• the district would risk losing a federal contract or federal funding; or

• another applicable law makes cannabis testing a mandatory requirement of that particular position. (Department of Labor)

The clearest school-district example is a school bus driver or other employee performing federally regulated, safety-sensitive transportation work. Federal DOT rules continue to require marijuana testing for covered school bus drivers. (Department of Transportation)

Merely describing a position as “safety-sensitive” does not automatically create an exception. The district should be able to identify the specific legal or governmental mandate authorizing or requiring cannabis testing.

Other drugs

The cannabis restriction does not necessarily prohibit a district from testing for other controlled substances. A district may be able to conduct a properly structured drug test for substances such as cocaine, opioids, amphetamines, or PCP, subject to:

• constitutional limits applicable to public employers;

• collective-bargaining agreements;

• district policy;

• disability-discrimination and medication protections;

• consistent and nondiscriminatory administration; and

• applicable civil-service or employment laws.

A panel that includes cannabis can create a problem even when the district is legally permitted to test for other substances. The district may need a test panel that excludes THC unless an exception applies.

Current employees and suspected impairment

A school district may prohibit:

• cannabis use during work hours;

• possession or use on school property;

• use in district vehicles; and

• working while impaired.

However, a positive cannabis test does not by itself establish current impairment, because THC metabolites can remain detectable long after the effects have ended. New York requires “specific articulable symptoms” showing that job performance is diminished or workplace safety is affected. Cannabis odor alone is not sufficient. (Department of Labor)

Practical examples

Bottom line

For most New York school employees, a district should not reject an applicant merely because of lawful off-duty cannabis use or a positive THC result. Testing remains appropriate for certain federally regulated transportation positions and other narrowly defined exceptions.

Districts considering a testing program should have counsel review the job classification, testing panel, collective-bargaining provisions, consent forms, and written policy before implementation. This is general information, not a legal opinion.
