Pittsburgh’s marijuana laws sit on top of Pennsylvania’s, and the two do not agree. Inside city limits, possessing 30 grams or less is a summary violation with a $25 fine under Pittsburgh City Code Chapter 627.1City of Pittsburgh, PA. City of Pittsburgh Code 627 – Marijuana Possession Procedure Under Pennsylvania state law, that same conduct is a criminal misdemeanor punishable by up to 30 days in jail and a $500 fine.2Pennsylvania General Assembly. Pennsylvania Code 35 PS 780-113 – Prohibited Acts and Penalties Which one you face depends on which officer stops you, and you don’t get to pick.
What Pittsburgh’s Ordinance Covers
Chapter 627 defines a “small amount” as 30 grams or less of marijuana or 8 grams or less of hashish. A Pittsburgh police officer who finds you with that amount issues a Notice of Violation carrying a $25 fine instead of making an arrest.1City of Pittsburgh, PA. City of Pittsburgh Code 627 – Marijuana Possession Procedure Smoking or vaping marijuana in a public space is a separate violation with a $100 fine. The ordinance’s definition of smoking explicitly includes vaporizer devices, so a vape pen on the sidewalk triggers the higher fine.
When the person cited is a minor, the officer notifies a parent or guardian, issues the Notice of Violation to both, and the parent becomes responsible for the fine. Allegheny County substance abuse education contact information goes to the parent as well.
The ordinance says out loud what people often miss: it does not override Pennsylvania or federal law. Pittsburgh officers keep the discretion to make a full arrest if they have probable cause for something more than simple possession, such as distribution or possession of a larger quantity.1City of Pittsburgh, PA.

When State Law Applies Inside the City
Chapter 627 binds Pittsburgh Bureau of Police officers. It does not bind anyone else. Pennsylvania State Troopers, Allegheny County Sheriff’s deputies, and other non-city officers operating within Pittsburgh can and do enforce state drug law. A trooper stopping you on I-376 is not writing a $25 ticket.
Under Title 35 § 780-113, a first offense for 30 grams or less carries up to 30 days in jail, up to a $500 fine, and a permanent criminal record.2Pennsylvania General Assembly. Pennsylvania Code 35 PS 780-113 – Prohibited Acts and Penalties Larger quantities, packaging materials, or cash alongside the marijuana can push the charge into felony territory. Recreational marijuana has not been legalized in Pennsylvania as of 2026, so the state framework is not going away on its own.
Medical Marijuana Is the Only Legal Route
Pennsylvania’s Medical Marijuana Program, established under Act 16 of 2016, is the only path to legally possess marijuana in the state. Registered patients with a valid ID card can purchase from licensed dispensaries without fear of state prosecution.
Qualifying conditions include cancer, epilepsy, PTSD, severe chronic pain, anxiety disorders, opioid use disorder, Parkinson’s, multiple sclerosis, autism, terminal illness, and several others. Moderate to severe traumatic brain injury and Type II diabetes are approved for research purposes only.3Commonwealth of Pennsylvania. Medical Marijuana Patients
The process starts with certification from a physician registered with the Pennsylvania Department of Health, followed by online registration and a $50 application fee. Patients in certain government assistance programs may qualify for a fee reduction.3Commonwealth of Pennsylvania. Medical Marijuana Patients The registration renews on a 12-month cycle tied to your registration date, with an email reminder 30 days before the $50 fee is due.4Commonwealth of Pennsylvania. Renew – Medical Marijuana Letting the registration lapse strips your legal protection even if product is still in the house.
Patients can purchase up to a 90-day supply at a time, measured in medical marijuana units. Pennsylvania allows dry leaf for vaporization but continues to prohibit combustion smoking even for medical patients. Vaping, oils, tinctures, capsules, and topical products are approved. Consumption must be in a private setting; using medical marijuana in any public space violates both state law and the Pittsburgh ordinance.
The DUI Trap Every User Should Know
This is the section that catches people, and it catches medical patients hardest. Under 75 Pa.C.S. § 3802(d), it is illegal to drive with any detectable amount of a Schedule I controlled substance or its metabolites in your blood.5Pennsylvania General Assembly. Pennsylvania Code Title 75 Chapter 38 Section 3802 – Driving Under Influence of Alcohol or Controlled Substance Marijuana remains Schedule I in Pennsylvania, so this is a zero-tolerance rule. Prosecutors do not need to prove you were impaired; a positive blood test is the case.
A medical card is not a defense. Pennsylvania law says being legally entitled to use a controlled substance does not defeat a DUI charge, and courts have applied that to registered patients. THC metabolites can stay in the bloodstream for days or weeks after any effect has worn off, so someone who used their medication on a Friday night can still test positive the following Wednesday.
Marijuana DUI sits in the highest penalty tier. A first offense means at least 72 consecutive hours in jail, a fine between $1,000 and $5,000, a 12-month license suspension, mandatory alcohol highway safety school, and any drug and alcohol treatment the court orders. A second offense brings a minimum of 90 days in jail and at least $1,500 in fines. A third or subsequent offense means at least one year in prison and a minimum $2,500 fine.6Pennsylvania General Assembly. Pennsylvania Code Title 75 Chapter 38 Section 3804 – Penalties
First-time offenders with a clean record going back roughly 10 years may qualify for the Accelerated Rehabilitative Disposition (ARD) program. ARD is not a conviction, and successful completion results in dismissal and automatic expungement. The District Attorney has sole discretion to approve applications, program fees usually run around $1,500, and eligibility generally requires that no one was injured and no passenger under 14 was in the vehicle. An ARD still counts as a prior offense for sentencing if you pick up another DUI within 10 years.
Firearms and a Medical Card Do Not Mix
Federal law prohibits any “unlawful user of or addicted to any controlled substance” from possessing firearms or ammunition, and because marijuana is Schedule I federally, the prohibition covers medical cardholders too.7Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The Pennsylvania State Police Firearms Division has said that a medical marijuana card makes you ineligible to apply for, possess, or renew a Pennsylvania License to Carry Firearms.
The practical bind: registering for the program creates a documented record of controlled substance use, and if you already own firearms, that record can be used against you federally. If you hold a License to Carry and apply for a card, you cannot legally renew the license. There is no state-authorized medical exception at the federal level.
Employment Protections in the City
Pittsburgh passed an ordinance in September 2024 that restricts employer drug testing for registered medical marijuana patients. Employers with five or more employees generally cannot require pre-employment marijuana testing of applicants who hold a valid Pennsylvania medical card, and testing of current cardholding employees is limited unless the employer has reasonable suspicion of workplace impairment.
The exceptions are substantial. The protections do not apply to positions regulated by the U.S. or Pennsylvania Departments of Transportation, positions requiring a firearm, or positions covered by a collective bargaining agreement that addresses drug testing. Employers can still ban marijuana use at work, conduct for-cause testing after an accident, test for other substances, and discipline conduct that falls below the standard of care for the role. The ordinance sets 10 nanograms of active THC per milliliter of blood as the threshold for being “under the influence” in certain safety-sensitive situations.
The ordinance only protects registered patients. Recreational users have no coverage. Employers with fewer than five employees, and employers outside city limits, are not bound.
Federal Property and HUD Housing
Federal law governs exclusively on federal property, including federal courthouses, national historic sites, and military facilities within the city. Possessing any amount of marijuana on federal property is a federal crime regardless of your medical card or Pittsburgh’s ordinance, and a first offense can bring up to one year in prison and a minimum $1,000 fine.8Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession
Federally subsidized housing carries its own rules. Under the Quality Housing and Work Responsibility Act, property owners receiving HUD funding must deny admission to current marijuana users and must keep policies allowing termination of tenancies for marijuana use. A medical card offers no protection because the federal government does not recognize state medical programs. Private Pittsburgh landlords are not bound by those HUD rules, but Pennsylvania has no law stopping private landlords from writing marijuana restrictions into leases or acting on them.
Delta-8 and Hemp-Derived Products
Delta-8 THC products derived from hemp sit in a legal gray area. Under the federal Farm Bill and Pennsylvania’s Act 92, hemp-derived products with less than 0.3% Delta-9 THC by dry weight are treated as legal agricultural products. Delta-8 is widely sold by hemp retailers without a medical card, and most retailers enforce a minimum age of 21.
At the same time, Pennsylvania’s Controlled Substance, Drug, Device and Cosmetic Act classifies THC isomers as Schedule I, and delta-8 is a THC isomer. Enforcement has been inconsistent across counties. A positive drug test from delta-8 use looks the same as one from traditional marijuana, so the DUI risk behind the wheel is identical.
