Pennsylvania's employment protections for medical marijuana patients

What an employer cannot do

Under the Medical Marijuana Act, a Pennsylvania employer may not discharge, threaten, refuse to hire or otherwise discriminate or retaliate against an employee solely because the employee is certified to use medical marijuana. Because refusing to hire is on that list, the protection reaches job applicants as well as current employees.

The phrase "solely because" sets the limit. The law protects your status as a certified patient. It does not turn the card into a shield for anything else that happens at work, which is why the exceptions below matter as much as the rule.

What an employer still may do

The same part of the act gives employers room in three directions:

• An employer does not have to accommodate the use of medical marijuana on workplace premises.
• An employer may discipline an employee for being under the influence at work when the employee's conduct falls below the accepted standard of care.
• Nothing in the act requires an employer to violate federal law.

The second point is worth reading closely. The trigger is conduct below the accepted standard of care, while under the influence. That is a test of performance and safety, not of whether you hold a card.

Duties an employer can restrict

Separately, the act lets employers bar patients from certain duties while under the influence of medical marijuana:

• work at heights or in confined spaces
• tasks that could create a risk to public health or safety
• tasks that are life-threatening to the employee or to others

The act also sets a hard number for some work. A patient may not operate or be in physical control of regulated chemicals, or of high-voltage electricity or other public utilities, while having more than 10 nanograms of active THC per milliliter of blood serum. Our page on patient rules places that limit alongside the possession and product rules.

Licenses, custody and arrest

The workplace section sits beside broader protections. A patient is not subject to arrest, prosecution or discipline by a professional licensing board solely for the lawful use of medical marijuana. In a child custody proceeding, a court may not consider the certification alone. Again, "solely" and "alone" mark the edge: lawful use is protected, and conduct beyond it is judged on its own.

Why the card itself matters

The protections attach to people who are certified to use medical marijuana. Adult use is not legal in Pennsylvania, according to reporting as of October 2026, so use outside the program has no equivalent protection. Our explainer on marijuana's legal status in Pennsylvania covers that background. Keeping your certification current is part of keeping the protection; the renewal guide explains the annual cycle.

Practical steps if you are concerned

• Read your employer's written drug and safety policies, and note any duties in your job that fall into the categories above.
• Keep your ID card current and with you whenever you possess medical marijuana, as the law requires.
• If you believe you were treated differently only because you are certified, write down dates and what was said, and talk to an employment lawyer. We cannot give legal advice.
