Cannabis Law

Our attorneys offer a full suite of legal services to assist our clients in navigating the complex and evolving landscape of the cannabis industry. Specifically, our firm’s understanding of the unique challenges of the industry allows us to defend lawsuits brought against cannabis industry defendants as well as evaluate coverage and defend lawsuits on behalf of industry insurers, agents and MGAs.

Insurance Coverage

We are familiar with the underwriting goals of industry insurers and MGAs, the policies drafted to reflect those goals and the unique risks inherent in the developing industry. We are experienced in analyzing coverage under cannabis policies as well as defending both breach of contract and bad faith lawsuits filed by insureds under cannabis policies.

We analyze coverage and defend claims under Commercial Property, including associated business interruption and cannabis CGL policies as well as cannabis related Management Liability/Professional Liability, Cyber and other claims made policies. The coverages analyzed include:

  • Property & Inland Marine: Fire, theft, water damage, and transport losses
  • Crop/Equipment: Claims involving mechanical failures or crop value loss
  • Cannabis Stock & Crime: Theft, employee dishonesty, and inventory loss
  • Duty to defend/coverage analysis under CGL or professional liability/claims made policies

Casualty

We deliver targeted, insurance-focused representation across a wide range of casualty claims, relevant to cannabis operations. We defend insureds for every general liability exposure, including:

  • CGL: Dispensary slip-and-falls, solvent explosions, and the myriad of accidental injuries associated with agricultural and commercial premises risks
  • Product Liability: Contamination, mislabeling, or accidental ingestion
  • Auto Liability: Accidents involving cannabis product delivery or transport
  • "Gram-Shop": Liability for providing cannabis to intoxicated patrons
  • Retail Accessory Risks: Injuries from broken glassware or accessories
  • Landlord Liability: Issues arising from leasing to cannabis businesses
  • Delivery Services: Claims tied to third-party logistics or on-demand delivery models

Management Liability/Employment

The cannabis industry is particularly susceptible to management liability and employment-related lawsuits due to its evolving legal and operational landscape. Common areas of litigation within these areas of law include:

  • Claims against company leaders: Stemming from their managerial choices
  • Wage and hour disputes: Misclassification of employees (exempt vs. non-exempt), failure to pay overtime, inaccurate timekeeping, and denial of breaks are common issues leading to lawsuits.
  • Discrimination and harassment: Employees bringing claims under Title VII and other anti-discrimination laws, alleging harassment and discrimination based on sex, race, and other protected characteristics.
  • Wrongful termination: Employees may claim wrongful termination based on various factors, including protesting discriminatory practices or exercising their rights related to cannabis use where protected by state law.
  • Retaliation: Employees who report workplace violations or engage in protected activities are also filing retaliation claims.

Professional Liability

Defending professional liability claims in the cannabis industry involves a combination of a history and experience defending a myriad of professional liability claims irrespective of the industry as well as an understanding of the unique risks for professionals servicing the cannabis industry. Our professional liability attorneys bring decades of experience defending professionals across many industries and are able to bring that experience to assist cannabis professionals including:

  • growers and cultivators
  • testing labs
  • consultants
  • accountants
  • architects
  • directors and officers
  • lawyers
  • MGAs/ independent adjusters
  • agents
  • software providers

Cyber / Data Breach

Cannabis operators must comply with rigorous cybersecurity standards to safeguard sensitive data and uphold both state and federal regulatory and privacy mandates. Because the cannabis supply chain relies heavily on digital tracking systems, cannabis-related businesses must deploy specialized software tools that secure inventory management and ensure accurate, compliant reporting, such as track and trace software that creates additional cyber vulnerabilities. Our Cyber team is available to quickly mobilize to mitigate the damage due to ransomware attacks and data-breaches.

Workers’ Compensation

Defending workers’ compensation claims in the cannabis industry requires navigating an evolving legal landscape. Our team focuses exclusively on representing insurers and employers in workplace injury and occupational hazard claims, while also offering proactive risk management strategies to help reduce exposure.

Cannabis Industry-Specific Risks and Exposures

  • Cultivation: Pesticide exposure, ergonomic strain; machinery accidents; electrical hazards
  • Manufacturing: Chemical exposure from extraction processes; industrial accidents involving heavy machinery
  • Retail and Distribution: Slip-and-falls; repetitive motion injuries; ergonomic strain; driver injuries

As the cannabis industry grows and regulations shift, our focused approach helps clients confidently manage workers’ compensation claims and minimize liability in this high-risk sector.

Health Care

While many states have legalized medical use of cannabis, it remains illegal under federal law. This dichotomy creates significant legal challenges for health care providers. We leverage our experience in helping clients navigate health care regulations such as HIPAA laws and patient privacy protections and apply it to the uniquely complex environment surrounding the cannabis industry. We defend clients against civil claims, including medical malpractice, and can assist health care providers – including physicians, dispensaries and clinics – to understand the evolving standards of care for cannabis as a therapeutic option, which can differ significantly from conventional treatments. This can include appropriate patient evaluations, dosage recommendations and documentation requirements within the framework of state medical cannabis programs. We are also well-equipped to address challenges related to informed consent.

Our Cannabis Law Practice serves clients from our 19 offices located throughout Pennsylvania, New Jersey, New York, Delaware, Florida, Ohio and Connecticut, and in neighboring jurisdictions in Maryland, West Virginia and Kentucky.

Marijuana Reclassified: Preliminary Impacts on Homeowners Coverage Issues

April 27, 2026

On April 23, 2026, the United States Department of Justice and Drug Enforcement Administration announced an order reclassifying certain marijuana products from Schedule I to Schedule III under the Federal Controlled Substances Act. This move represents the most significant shift in federal cannabis policy in decades. While much of the public discussion thus far has focused on the tax and criminal implications of the change, there are more nuanced questions for insurers – particularly in the context of homeowners policies and the enforceability of exclusions for “controlled dangerous substances.” The Regulatory Shift For decades, marijuana was classified as a Schedule I drug under the Controlled Substances Act. That classification, on a tier reserved for substances with no accepted medical use and a high potential for abuse, aligned marijuana with substances like heroin, LSD and peyote. The April 2026 order altered that framework by recognizing that FDA-approved products containing marijuana and marijuana products regulated by a state medical marijuana license will be reclassified in Schedule III of the Controlled Substances Act. This move indicates at least some level of federal recognition that state-licensed marijuana has accepted medical uses and a lower potential for abuse.  Importantly, the change is limited. The reclassification does not federally legalize marijuana, and recreational cannabis generally remains a Schedule I substance. This bifurcated treatment of medical versus recreational marijuana use will likely become central to future discussions, including insurance coverage litigation. Implications for Homeowners Policies Most standard homeowners policies contain exclusions for losses “arising out of” the use, sale, manufacture, delivery, transfer or possession of controlled substances, as defined by the Federal act. Notably, the standard “controlled substances” exclusion in policies specifically references cocaine, LSD, marijuana and narcotic drugs. The rescheduling of marijuana to Schedule III raises the key question of how or whether the “controlled substances” exclusion will continue to apply. At this point, the answer to this question appears to be that the provision will continue to preclude coverage for losses arising out of marijuana claims, since Schedule III substances remain “controlled substances” under federal law and marijuana remains listed, by name, in the exclusion. To be clear, the reclassification does not remove marijuana from the statutory framework; it merely places marijuana in a less restrictive category of the Controlled Substances Act. Moving forward, insurers will likely argue that the plain language of the exclusion means that the provision continues to apply. For their part, policyholders may begin to push back on that interpretation, particularly in jurisdictions like Pennsylvania and New Jersey, where legalized cannabis regimes are well-established. The argument will be that conduct authorized by state law, and now partially recognized at the federal level, should not trigger exclusions designed to address criminal or inherently hazardous activity. Ultimately, any coverage disputes will likely turn on traditional principles of policy interpretation: plain meaning, ambiguity, and the reasonable expectations of the insured. Courts in Pennsylvania and New Jersey, both of which have robust bodies of insurance coverage law, will play an important role in shaping how these disputes are resolved. Conclusion The move of FDA-approved drug products containing marijuana and medicinal marijuana products subject to a qualifying state-issued license to Schedule III is an important step in federal drug policy, but its immediate impact on homeowners insurance is limited. Simply put, marijuana remains a controlled substance, such that standard exclusions to homeowners policies should continue to apply. Moving forward, the most significant effects of the change in classification will emerge in close cases, particularly in states like New Jersey where recreational and medical marijuana is legal (at least to some degree) under state law. For now, the change creates more questions than answers. Those questions, which are likely to be centered on policy language, legality, and causation, are likely to shape the next wave of coverage litigation in this area.

The Ohio Supreme Court Extends Sham-Affidavit Rule to Contradictory Expert Reports

Legal Roundup: Ohio In its June 23, 2026, decision in Moore v. Mercy Medical Center, the Ohio Supreme Court upheld a trial court’s decision to strike an expert witness’s affidavit that contradicted the opinions expressed in the expert’s prior report. This case pertains to allegations of medical malpractice after plaintiff Cheri Moore gave birth to an infant in respiratory distress who required intubation. Moore alleged that a delay in ordering an emergency cesarean section resulted in the need for intubation, causing her child’s injuries. Specifically, Moore sued Dr. Meniru, who completed his first shift at 7:00 a.m. on May 28, 2015, and did not resume treating Moore until 7:00 a.m. on May 29, 2015. One of Moore’s expert witnesses authored a report stating that the doctors, including Dr. Meniru, deviated from the standard of care by not advocating for a cesarean section in the evening of May 28, 2015. Based on this report, Dr. Meniru moved for summary judgment, arguing that the alleged breach occurred during a period when he was not on duty. In response to the summary judgment motion, the plaintiff filed an affidavit from the same expert. Although the expert expressly incorporated his previous report into his affidavit, he also offered an additional opinion: that Dr. Meniru breached the standard of care by failing to begin a cesarean section within 30 minutes of receiving reports of fetal distress. Dr. Meniru filed a motion to strike the expert’s affidavit, arguing that it contradicted the opinions set forth in his prior report in violation of the sham-affidavit rule. The sham-affidavit rule applies to “a contradictory affidavit that indicates only that the affiant cannot maintain a consistent story, or is willing to offer a statement solely for the purpose of defeating summary judgment”. Moore, supra, at ¶ 19, citing Pettiford v. Aggarwal, 126 Ohio St.3d 413, 2010-Ohio-3237. The trial court granted both the motion to strike and the motion for summary judgment, and the Fifth District affirmed. The Ohio Supreme Court accepted two questions of law: (1) whether the sham-affidavit rule applies when the sworn testimony contradicts prior unsworn statements; and (2) whether an inconsistency within the affidavit goes to credibility or admissibility, justifying an order striking the affidavit. Previous rulings by the Ohio Supreme Court regarding the sham-affidavit rule have pertained to contradictions between an affidavit and sworn deposition testimony. See, e.g., Byrd v. Smith, 2006- Ohio-3455, 110 Ohio St.3d 24, 850 N.E.2d 47. However, here, the Court was asked to apply the same rule to contradictions between a sworn affidavit and an unsworn expert report. The Court held that, because Moore’s expert incorporated his prior report into his affidavit, he effectively adopted the report as part of his sworn testimony.

Pennsylvania Superior Court Reaffirms Liberal Pleading Standard in Medical Malpractice Actions

Legal Roundup: Pennsylvania The Pennsylvania Superior Court has reinforced a broader fact-pleading approach that may make it more difficult for health care defendants to obtain dismissal at the preliminary objection stage. In DaSilva v. Abington Memorial Hospital, the court held that the plaintiffs’ second amended complaint satisfied Pennsylvania’s fact‑pleading requirements despite the absence of individually named negligent actors. In DaSilva, the plaintiffs filed a second amended complaint alleging that Abington Memorial Hospital was directly and vicariously negligent after the patient, who was experiencing a mental health crisis, was left unattended by hospital staff, exited the emergency department, and was struck by a vehicle, suffering serious injuries. The trial court sustained the hospital’s preliminary objections and dismissed the complaint with prejudice, stating plaintiffs “failed to plead any material factual allegations in support of their claims of negligence [and] set forth vague allegations of negligence and unidentified agency.” Id. at *5. The plaintiffs appealed. On appeal, the Superior Court reversed, holding that the complaint sufficiently pled negligence and vicarious liability claims under Pa.R.C.P. 1019(a). The court concluded that allegations describing the patient’s condition, the hospital’s awareness of that condition, and the alleged failure to monitor or prevent elopement were adequate to satisfy Pennsylvania’s pleading requirements. Significantly, the court rejected the hospital’s argument that the complaint failed because it did not identify the specific employees responsible for the alleged negligence. Instead, the court found that generalized references to “emergency room staff” were sufficient to place the hospital on notice of the claims because “the names of those who performed services for the plaintiff are known to the defendant or can be ascertained during discovery.” Id. at *12 (citing Est. of Denmark ex rel. Hurst v. Williams, 117 A.3d 300, 307 (Pa. Super. 2015)). The effect of DaSilva is that plaintiffs may proceed past the pleading stage with relatively generalized allegations, particularly in cases involving institutional defendants where relevant details are uniquely within the defendant’s control. As a result, health care defendants should anticipate that challenges to claim sufficiency may be resolved in the later stages of litigation, including discovery and summary judgment.
