Cannabis Laws in Pennsylvania

Current Legal Status

Pennsylvania legalized medical cannabis in April 2016 when Governor Tom Wolf signed Act 16, the Medical Marijuana Act ^[1]. The program launched dispensary sales in February 2018 and has grown into one of the largest medical programs in the country, with more than 400,000 active patients as of recent state reporting ^[2].

Adult-use (recreational) cannabis remains illegal under Pennsylvania state law. Possession of 30 grams or less of marijuana, or 8 grams or less of hashish, is a misdemeanor punishable by up to 30 days in jail and a $500 fine under 35 P.S. § 780-113(a)(31) ^[3]. Possession of larger amounts is a misdemeanor carrying up to one year in jail and a $5,000 fine. Sale or distribution charges escalate quickly into felony territory.

The Medical Marijuana Program

The PA Department of Health's Office of Medical Marijuana oversees the program. To qualify, a patient must be a Pennsylvania resident under the care of an approved practitioner and have one of 23 listed serious medical conditions, including chronic pain, PTSD, cancer, epilepsy, anxiety disorders, opioid use disorder, and others ^[4].

Key program rules:

• Patient card cost: $50 application fee (reduced or waived for SNAP, Medicaid, PACE, CHIP, and WIC participants).
• Practitioner certification: Required every year; physicians must complete a state-approved training course.
• Product forms: Pills, oils, topicals, tinctures, vape concentrates, and dry leaf/flower for vaporization are permitted. Smoking is technically not permitted under the statute, though flower sold for vaporization is widely used.
• Purchase limit: A 90-day supply, as determined by the certifying practitioner.
• Home cultivation: Not allowed under any circumstance, including for patients ^[1].
• Reciprocity: Pennsylvania does not honor out-of-state medical cards for purchases at PA dispensaries.

Products are sold through state-licensed dispensaries, with around 190 locations operating statewide as of 2024 ^[2].

Local Decriminalization

Several Pennsylvania municipalities have passed local ordinances that allow police to issue civil citations rather than file criminal charges for small-amount possession. Philadelphia was first in 2014, treating possession of up to 30g as a $25 civil violation and public use as a $100 fine ^[5]. Pittsburgh followed in 2015, with Harrisburg, Erie, State College, Lancaster, York, Allentown, and Bethlehem enacting similar measures over the following years ^[6].

Important caveats:

• These are local ordinances. State law has not changed. Police in these cities retain discretion to charge under state law, and incidents involving Pennsylvania State Police or federal officers (e.g., on highways or federal land) are not governed by city ordinances.
• Enforcement patterns vary significantly. ACLU of Pennsylvania reporting has documented continued racial disparities in arrests even in decriminalized cities ^[7].
• Driving under the influence of cannabis (75 Pa.C.S. § 3802) is a separate offense and is not affected by decriminalization.

DUI and Workplace Issues

Pennsylvania historically applied a zero-tolerance standard for THC in DUI cases: any detectable amount of Schedule I metabolites in blood could support a DUI conviction under 75 Pa.C.S. § 3802(d)(1), even days after use when impairment is no longer present. In 2024, the Pennsylvania Supreme Court in Commonwealth v. Stone and related rulings, along with statutory developments, narrowed but did not eliminate this approach for registered medical patients ^[8]. The law in this area is actively evolving and remains a serious risk for any cannabis user driving in PA.

For employment, Pennsylvania's Medical Marijuana Act provides limited anti-discrimination protections: employers cannot discharge or discriminate against an employee solely on the basis of certified patient status. However, employers may still prohibit being under the influence at work, and safety-sensitive roles (operating heavy machinery, working at heights, etc.) are explicitly carved out ^[1].

Adult-Use Legalization Efforts

Adult-use legalization bills have been introduced in nearly every recent legislative session. Governor Josh Shapiro included adult-use legalization in his budget proposals in 2024 and 2025, projecting hundreds of millions of dollars in annual tax revenue ^[9]. In May 2025, the Pennsylvania House passed HB 1200, which would have legalized adult-use cannabis through a state-store retail model, but the bill stalled in the Senate ^[10].

As of the last verification date on this article, no adult-use legalization bill has been enacted. The political dynamic — a Democratic governor and House versus a Republican-controlled Senate — has been the main obstacle. Reform advocates expect continued legislative attempts, but no enactment is guaranteed in any particular session. Pennsylvania is now nearly surrounded by states with legal adult-use markets (NJ, NY, MD, OH, DE), which has intensified the political pressure but has not yet produced a deal.

Federal Law Still Applies

Cannabis remains a Schedule I substance under the federal Controlled Substances Act Strong evidence. This affects:

• Federal land: National parks, federal buildings, and military installations within PA are subject to federal law regardless of state status.
• Firearms: Federal law (18 U.S.C. § 922(g)(3)) prohibits cannabis users — including registered medical patients — from purchasing or possessing firearms. ATF Form 4473 requires disclosure ^[11].
• Immigration: Cannabis-related conduct can have severe immigration consequences even where legal under state law.
• Federal employment and security clearances: Generally disqualifying.

In 2024 the DEA began a formal process to reschedule cannabis from Schedule I to Schedule III; as of the last verification date, that process is ongoing and has not concluded ^[12].
