Yes, nurses in Pennsylvania can have a medical marijuana card. State law allows any resident with a qualifying condition to register as a patient, and the Pennsylvania State Board of Nursing does not prohibit licensed nurses from doing so. Holding a card is not, by itself, a disciplinary matter and does not have to be disclosed to the Board. The real risk for nurses is not the card; it is impairment on the job, a positive drug screen at work, and the way employers, the Board, and federal rules each treat cannabis differently.
What the Board of Nursing Actually Regulates
The Board does not have a rule against being a certified medical marijuana patient, and nothing requires you to notify it that you hold a card. Pennsylvania’s nursing conduct regulations focus on something else: whether you are competent to practice safely and whether your conduct meets the accepted standard of care.1Pennsylvania Code and Bulletin. 49 Pa Code 21.18 – Standards of Nursing Conduct If a nurse works while impaired by any substance, the Board can discipline the license, up to suspension or revocation.
There is no set THC blood level that defines impairment for nurses. The Board looks at conduct and care, not a number. That cuts both ways. A positive drug test alone does not prove you were impaired at the bedside, because cannabis metabolites can show up on a screen for weeks after use. But a positive screen combined with any performance concern can trigger an employer investigation and a Board referral.
Employment Protection Under Section 2103
Section 2103 of the Medical Marijuana Act bars employers from firing, refusing to hire, threatening, or retaliating against an employee solely because the employee is certified to use medical marijuana.2Pennsylvania General Assembly. Act No. 16 of 2016 – Medical Marijuana Act “Solely” is doing most of the work in that sentence. If a hospital fires a nurse just for holding a card, that violates the Act. If it fires a nurse for working impaired, it does not.
The same section says employers are not required to permit cannabis use on their premises and can discipline employees whose conduct “falls below the standard of care normally accepted for that position.” Nursing’s standard of care is high, and the carve-out gives healthcare employers wide authority to run strict drug programs for clinical staff even though Pennsylvania’s statute does not use the phrase “safety-sensitive position.”
In practice, that means:
- Most hospitals and healthcare employers conduct pre-employment, post-incident, and sometimes random drug testing.
- A valid medical card does not exempt you from those tests.
- Employers vary in how they treat a positive screen with no performance issue; many do not distinguish.
If a Problem Does Surface: The Impaired Professionals Program
Pennsylvania’s Professional Nursing Law includes an Impaired Professionals Program that lets the Board defer discipline while a nurse participates in approved treatment.3Pennsylvania General Assembly. Act of May 22, 1951, P.L. 317, No. 69 Cl. 63 – Section 14.1 The Bureau of Professional and Occupational Affairs runs a Voluntary Recovery Program under its Professional Health Monitoring Programs for licensed professionals with substance use disorders or mental health conditions.4Commonwealth of Pennsylvania. Professional Health Monitoring Programs A suspension or revocation can be stayed for the length of successful participation, and the corrective action can ultimately be dismissed if the nurse completes the program and aftercare.
One limit: a nurse convicted of a felony drug offense cannot use this program, and the Board moves ahead with standard discipline.
The Multistate License Complication
Pennsylvania fully implemented the Nurse Licensure Compact on July 7, 2025, so a nurse with a multistate license can practice across member states without separate licensure.5National Council of State Boards of Nursing. Pennsylvania to Fully Implement Nurse Licensure Compact (NLC) If you hold or want multistate privileges, a cannabis-related incident can cost you more than your Pennsylvania job.
Compact rules require an active, unencumbered license and no current participation in an alternative monitoring program. The Compact defines a “disqualifying event” to include current participation in such a program, any adverse action resulting in an encumbrance, and certain criminal convictions.6National Council of State Boards of Nursing. Interstate Commission of Nurse Licensure Compact Administrators Rules A nurse who enters Pennsylvania’s Voluntary Recovery Program loses multistate privileges for the duration of that participation.
Marijuana laws also differ sharply among compact states. Lawful off-duty use in Pennsylvania may be treated differently by a board or employer in another member state where you practice under your multistate license. If you work across state lines, check the rules in every state where you may practice.
Federal Employers Are a Separate World
Marijuana is still a Schedule I controlled substance under the federal Controlled Substances Act.7Drug Enforcement Administration. Drug Scheduling State medical marijuana protections do not override federal workplace rules. If you work for a VA hospital, a federal prison healthcare unit, or any facility operating under federal employment rules, Section 2103 does not apply to you, and marijuana use can lead to termination regardless of your Pennsylvania card.
Facilities that receive Medicare, Medicaid, or federal grants face their own compliance obligations under the Drug-Free Workplace Act of 1988, and those policies reference federal drug schedules rather than state law. Many take the position that any clinical-staff marijuana use conflicts with their federal obligations.
What to Do Before You Register
If you have decided a card makes sense for your condition, a few steps protect your license and your job.
- Read your employer’s drug policy carefully. Know what triggers a test, what the facility does with a positive screen, and whether it distinguishes between a positive result and observed impairment.
- Build real distance between use and work. There is no agreed-upon window where impairment has ended but a test will come back negative, so use on days off and well before any shift is the only reliable approach.
- If you hold or want a multistate license, understand that discipline or entry into a monitoring program after a workplace cannabis incident is a disqualifying event for compact privileges.
- Keep records of your physician certification, qualifying condition, and dispensary purchases in case you need to show that your use was medically authorized.
- If your employer is federal, assume state protection does not reach you.
The short version: the card is legal, the Board will not come after you for having one, and your employer cannot fire you just because you hold it. Everything else depends on whether cannabis shows up in your work, in a test, or in your performance. Treat it the way you would treat any prescription that can affect alertness, keep it far from your shifts, and know your employer’s rules before you need them.
