Mary Jane Berlin Celebrates 10th Anniversary With Record Attendance and Industry Leaders

Mary Jane Berlin is set to mark its milestone 10th anniversary from June 11 to 14, 2026, at Messe Berlin, drawing more than 75,000 attendees and over 500 exhibitors. The event, one of the largest global cannabis gatherings, reflects Germany’s rapid ascent as Europe’s largest legal cannabis market since the country's landmark legalization of recreational cannabis in April 2024. According to organizers, the festival's expansion mirrors the transformation of Germany's cannabis sector and the continent’s growing interest in regulated markets

The festival's programming is split between an exclusive B2B day on June 11—reserved for industry professionals—and a public festival from June 12 to 14. The B2B day features conference panels, networking sessions, and a headline live podcast taping with RAW founder and High Times publisher Josh Kesselman in conversation with Mary Jane Berlin co-founder Duc Anh Dang. "Two completely different paths to building enduring cannabis brands at scale," organizers describe, highlighting the unique journeys of Kesselman and Dang in shaping global cannabis culture

The festival continues to honor its cultural roots, offering a blend of business and community-focused activities. The expo floor now brings together international cultivation operators, medical cannabis companies, and ancillary service providers, all eager to launch and expand their presence in the German market. Meanwhile, the public festival features a robust music lineup with artists such as Marteria, Samy Deluxe, and Berlin underground acts, alongside wellness programming like guided meditation and sound baths. The event maintains a "care culture" infrastructure, including awareness teams and free water stations, and enforces an alcohol-free, smoking-regulated environment

High Times editor in chief Javier Hasse will be present throughout the event, meeting with industry operators and reporting on developments from the conference floor. Additional CEO conversations are scheduled across the week, featuring leaders such as Jürgen Bickel of Storz & Bickel, Benedict Sons of Cansativa, and David Ulbing of Cannafleur. The event's structure, with its dedicated B2B and public segments, is seen as a model for cannabis expos worldwide. "It’s the format US events have been talking about for years. Mary Jane just keeps doing it," the organizers note

From the OG Lab newsroom perspective, Mary Jane Berlin’s evolution into a hybrid B2B and cultural festival underscores Germany’s central role in shaping the future of the European cannabis industry. The event’s growth and innovative format are likely to influence how cannabis conventions are structured across the region. As Germany’s legal market matures, industry stakeholders will watch Mary Jane Berlin for cues on both business strategy and community engagement
