How Smoking, Bad Packaging, or Driving After Using Medical Marijuana Can Lead to Criminal Charges in Pennsylvania

How Smoking, Bad Packaging, or Driving After Using Medical Marijuana Can Lead to Criminal Charges in Pennsylvania

Having a Medical Marijuana Patient Card in Pennsylvania does not provide you with blanket protection from marijuana-related charges. The Pennsylvania Medical Marijuana Act only protects specific, narrowly-defined conduct. Patients who step outside those boundaries, even unknowingly, can find themselves facing criminal charges.

Below is an overview of the most common ways medical marijuana patients run into trouble: smoking their medicine, not carrying medical marijuana in its original packaging during transport, and driving after use.

Section 303: What the Medical Marijuana Act Actually Allows

Pennsylvania's Medical Marijuana Act, 35 P.S. §§ 10231.101 et seq., only protects patients who are certified by an approved physician, registered with the Department of Health, and in possession of a valid medical marijuana ID card. Even for those patients, the Act limits lawful use to specific forms of the product under Section 303:

• Pill

• Oil

• Topical forms, including gels, creams, and ointments

• Tincture

• Liquid

• Dry leaf for vaporization or nebulization only.

Smoking is expressly prohibited. Although the sale of dry leaf (flower) was ultimately approved, smoking the product remains illegal under Pennsylvania law.

Sections 303 and 801: Original Packaging Requirements

Section 303(6) of the Act provides that “Medical marijuana that has not been used by the patient shall be kept in the original package in which it was dispensed.”

Section 801(i) of the Act requires dispensaries to dispense medical marijuana in a sealed, labeled package. The labeling must contain the packaging date, a final usage date, warnings related to health and driving impairment, dosage and potency information, along with warnings that medical marijuana must be kept in its original container. Further, the label must include a warning that unauthorized use will be subject to criminal penalties.

Section 304: Unlawful Use of Medical Marijuana

Section 304 of the Act specifically identifies conduct that falls outside the protection of a medical marijuana card, including:

• Smoking medical marijuana;

• Incorporating Medical Marijuana into edible form unless permissible to aid with ingestion;

• Growing Medical Marijuana without a permit; AND

• Dispensing Medical Marijuana without authorization;

Driving After Using Medical Marijuana: The Zero-Tolerance Problem

Perhaps the most misunderstood risk facing medical marijuana patients in Pennsylvania involves driving. Many patients assume that because their marijuana use is legal, they cannot be charged with DUI for using it and then driving. That assumption is incorrect.

Pennsylvania’s Marijuana DUI Statute makes it a crime to drive with any amount of a Schedule I controlled substance, or its metabolite, in your bloodstream. Marijuana remains a Schedule I substance under Pennsylvania's Controlled Substances Act regardless of a patient's medical marijuana card. THC metabolites can linger in the blood for days or weeks after use, long after any impairing effect has worn off.

The Pennsylvania Superior Court has directly addressed whether a valid medical marijuana card provides a defense to this zero-tolerance standard. In an unpublished 2022 memorandum decision, Commonwealth v. Wagner, No. 491 WDA 2021 (Pa. Super. filed Apr. 5, 2022), the Superior Court held that the Medical Marijuana Act does not create an affirmative defense to DUI under Section 3802, and that the Commonwealth is not required to disprove that a defendant's THC came from a source other than lawfully-obtained medical marijuana. Specifically, the Medical Marijuana Act’s “silence regarding lawful driving,” does not create an affirmative defense.

In practice, this means a compliant, card-carrying patient who drives with any detectable trace of THC in their system can be prosecuted for DUI. This gap in the law has drawn criticism, and legislation has been repeatedly introduced in Harrisburg to require proof of actual impairment for medical marijuana patients, similar to how the law treats other prescription medications. As of now, none of those bills has been enacted, and Section 3802(d)(1)'s zero-tolerance standard remains the law.

Criminal Charges For Individuals Possessing Medical Marijuana

Keeping your medical marijuana in its original, labeled container is one of the simplest and most effective ways to avoid turning a lawful traffic stop into a drug investigation. We frequently get calls from individuals who unknowingly violate provisions of the Medical Marijuana Act, may face regular prosecution for criminal offenses, as follows:

• Possession of a Small Amount of Marijuana:

  • Possessing medical marijuana in an unlawful way, such as carrying it in a personal container, plastic bag, pill bottle or grinder;

  • Possessing a rolled joint or blunt containing medical marijuana, as smoking remains illegal, or

  • Possessing medical marijuana after making an admission to smoking it.

• Possession of Drug Paraphernalia:

  • Person with a lawful MMJ card is in possession of unlawful containers (non-original dispensary packaging)

  • Possession of devices used to illegally smoke medical marijuana such as pipes, bongs, blunts and related smoking devices

Practical Advice for Medical Marijuana Patients

• Vaporize, don't smoke. Only vaporization and nebulization are protected forms of consumption under the Act for plant material.

• Keep your marijuana in its original, labeled dispensary container, especially when transporting it in a vehicle. Transport only when necessary.

• Never share, gift, or sell your medical marijuana to anyone else, even another patient or a family member.

• Avoid driving if you have used any medical marijuana on a particular date. If you used medical marijuana in the morning, drive at night, and tell the officer you used in the morning, you just provided probable cause to believe you are driving with a Schedule I Controlled Substance in your blood.

• If you are stopped by police and have medical marijuana in your vehicle, you are not required to answer questions about your card, your usage habits, or where you're headed beyond what's required to identify yourself and produce your license, registration, and insurance.

Commonwealth v. Romanelli (2026): PA Superior Court Rules that Police May Add 22 Seconds to Traffic Stop to Ask About Marijuana Use

Commonwealth v. Romanelli (2026): PA Superior Court Rules that Police May Add 22 Seconds to Traffic Stop to Ask About Marijuana Use

Our firm has represented countless drivers who were pulled over for a minor traffic violation, only to have the stop turn into a DUI investigation within seconds. In Commonwealth v. Romanelli, the Pennsylvania Superior Court reversed a trial court's decision to suppress evidence, holding that a trooper's question about marijuana use — asked 22 seconds after ordering the driver out of his car — was still part of a lawful traffic stop, not a new detention requiring its own reasonable suspicion.

Com v. Romanelli: The Facts

On June 26, 2024, a Pennsylvania State Trooper was patrolling Route 15 in Adams County when he began following a Ford Edge that was traveling in the left lane of the highway for roughly four miles, even though the right lane was open. Believing this violated the Vehicle Code's requirement that drivers use the right-hand lane when it's available, the trooper initiated a traffic stop.

Approaching the vehicle, the trooper identified Jason Romanelli as the driver and saw three passengers inside. He noticed Romanelli's eyes were bloodshot and glassy. Citing officer safety — and the presence of the other occupants — the trooper asked Romanelli to step out of the car so he could speak with him separately. Within 22 seconds of that request, while a second trooper was still running Romanelli's license, registration, and insurance through police databases, the trooper asked Romanelli whether he had smoked marijuana that morning.

Romanelli admitted that he smoked a bowl around 7:30AM, and told the trooper he had a Maryland medical marijuana card. Notably, the trooper testified on cross-examination that he never actually smelled marijuana on Romanelli or in the vehicle. Before Romanelli got out of the car, bloodshot and glassy eyes were the only sign of possible impairment the trooper had observed. Based on the eye observation and Romanelli's admission, the trooper arrested him for suspected DUI.

Romanelli was charged with DUI and the underlying lane violation. He moved to suppress everything that happened after he exited the vehicle, arguing that once the trooper pivoted from the traffic stop to questioning him about marijuana, a brand-new investigative detention began — one that required its own reasonable suspicion of DUI, which the trooper didn't yet have. The trial court agreed and suppressed the evidence. The Commonwealth appealed.

Com v. Romanelli: The Law

Pennsylvania recognizes three levels of police-citizen interaction: a mere encounter (no suspicion needed), an investigative detention (requiring reasonable suspicion that criminal activity is afoot), and a custodial detention (the functional equivalent of arrest, requiring probable cause). For a traffic stop specifically, everything turns on the stop's "mission" — the traffic violation itself and any related safety concerns. A stop becomes unconstitutional the moment it runs longer than necessary to complete that mission. Critically, the Superior Court emphasized that the real question isn't when a question is asked relative to the citation being written — it's whether the question adds time to the stop.

During a lawful stop, officers may make routine inquiries tied to that mission — checking license, registration, insurance, and warrants — and may order occupants out of the vehicle for safety. But once the traffic mission is complete, that authority ends, and further questioning can create a new detention requiring independent justification.

To sort out where the marijuana question fell, the Superior Court adopted a four-part framework from a recent Third Circuit decision, dividing roadside questions into:

1. Small talk: social conversation with no constitutional significance;

2. Infraction-related inquiries: questions tied directly to the violation itself, such as license, registration, travel plans or other ordinary inquiries related to the traffic stop

3. Safety-related inquiries: questions connected to officer or roadway safety, such as questions about passengers or weapons; and

4. Off-mission inquiries: questions unrelated to the stop or officer safety, aimed at investigating other crimes, which generally require independent justification unless they don't meaningfully extend the stop.

Applying this framework, the Superior Court held that the marijuana question qualified as safety-related. or at minimum, a permissible off-mission question that ran concurrently with the ongoing traffic stop. Two facts drove the outcome:

• Timing: The trooper asked about marijuana while his partner was still actively running the routine license and registration checks. Because that "mission" work was ongoing, the marijuana question didn't add any time to the stop.

• Safety Framing: The trooper testified that Romanelli appeared "high," and the court accepted that a question about possible impairment can be legitimately tied to officer safety, especially with three additional occupants in the vehicle.

Because the question didn't prolong the stop, the court held it did not create a separate detention requiring its own reasonable suspicion. The court went a step further and held that even if a new detention had been created, the trooper had enough — bloodshot, glassy eyes, the admission of marijuana use roughly 90 minutes before driving, and Romanelli's overall appearance — to establish reasonable suspicion for field sobriety testing under the totality of the circumstances.

The Superior Court distinguished a prior case Romanelli relied on, Commonwealth v. Lomax, where an officer removed a passenger for field sobriety testing and repeatedly questioned him about marijuana without ever articulating a safety rationale, in a manner that extended the stop. Here, by contrast, the trooper gave a safety reason for the removal and the marijuana questioning at the same time as the ongoing document checks.

Com v. Romanelli: Why This Case Matters

This decision narrows the window defense attorneys have to challenge roadside questioning in DUI cases. Three things stand out:

• Seconds Matter: The outcome turned on the fact that a second trooper was still processing Romanelli's paperwork when the marijuana question was asked. Suppression motions built around an "off-mission questioning" theory now need a precise, second-by-second account of what each officer was doing and when. Dash-cam and body-cam timestamps can help paint that picture.

• Officer Safety: The court broadly accepted a safety rationale for both the order to exit the vehicle and the marijuana question based on little more than the presence of passengers and the driver's appearance.

• Four-Category Framework to Analyze Roadside Questions: The courts will carefully examine whether or not questions are considered small talk, infraction related, safety related or off-mission in analyzing the legality of police conduct.

Com v. Romanelli: The Takeaway for Pennsylvania Drivers

If you've been asked an unexpected question during a traffic stop about drugs, alcohol or something unrelated to the reason you were pulled over, don’t assume that the question was improper b/c it seemed off-topic. Off-topic questions can be lawful if asked while paperwork is being processed, or if it’s deemed tied to officer safety. At the same time, this is exactly the kind of fact-intensive issue where a skilled DUI defense attorney can make a real difference: the precise timing of the stop, what each officer was doing at each moment, and whether the government's safety rationale actually holds up are all things that require careful review of the dash-cam and body-cam footage — not assumptions.

At the Zuckerman Law Firm, we defend drivers charged with DUI and other criminal offenses throughout Western Pennsylvania. If your case started with a traffic stop that turned into something more, it's worth having the footage and the timeline reviewed by an experienced attorney before you assume nothing can be done.

Military Veteran receives 1 year of probation for 2 DUI cases in Bedford Co.

In 2016, our office was retained to represent a military veteran who picked up two separate DUI cases in quick succession. The client was charged at the first case with a DUI for the Highest Rate of Alcohol offense and Endangering the Welfare of a Child. At the second case, the client was charged with a DUI for a High Rate of Alcohol. She faced a total mandatory minimum jail sentence of 33 days in jail at both cases, and up to 5 and 1/2 years of total confinement or probationary supervision. 

Our office was able to negotiate an agreement for the client to plead guilty to DUI General Impairment charges, both of which were treated as first offenses. For first offense DUI General Impairment charges, there is no mandatory jail sentence, but a mandatory period of probation of 6 months at each case for a total of 1 year of probation. In negotiating this agreement, our office worked with the client to chronicle her military history, compile character reference letters, and provide documentation of treatment. Providing a vast array of mitigating documentation helped persuade the District Attorney's office to offer a favorable resolution of these cases.

4th Offense DUI Charges, Ignition Interlock Violations Dismissed for Allegheny County Man

A ZLF client was charged with a 4th Offense DUI in connection with a two-vehicle accident in Allegheny County. We are please to announce that after the preliminary hearing, the charges were dismissed due to a lack of sufficient evidence. This resolution spared the client from a mandatory 1-2 year state prison sentence without eligibility for house arrest. 

In the summer of 2016, the client was operating a vehicle around a bend when his vehicle hydroplaned on the wet roadway, veered into an oncoming lane of traffic, striking the victim's vehicle. An independent eyewitness followed the client's vehicle for approximately 1/2 mile, observing no erratic driving behaviors prior to the crash. 

The client was treated at the hospital for injuries in connection with the crash. In the course of his treatment, a urine screen yielded a positive result for the presence of narcotics. However, neither the client's blood nor breath were tested. The client was not subjected to field sobriety testing, was not evaluated by a drug recognition expert, and did not display regular signs of impairment during his interaction with police. 

Recent amendments to Section 1547 of the PA Motor Vehicle Code only permit the introduction of blood or breath tests into evidence during DUI prosecutions. As there was no blood test conducted, and there was no independent evidence to suggest that the client was under the influence of narcotics at the time of operation, the charges were properly dismissed by the Court.
