Mary Jane Berlin Hits 10. Here’s What’s Going Down At One Of The World’s Biggest Cannabis Events.

Mary Jane Berlin marks its 10th anniversary edition June 11-14 at Messe Berlin, with 75,000+ attendees and 500+ exhibitors expected. RAW founder and High Times publisher Josh Kesselman headlines a live podcast on opening day. High Times editor in chief Javier Hasse will be on the ground.

Germany legalized recreational cannabis in April 2024. Two years later, the country has the largest legal cannabis market in Europe, a swelling network of cultivation associations and the post-legalization commercial buildout that the rest of the continent is watching closely. The industry’s main meeting point is one weekend in Berlin in June.

Mary Jane Berlin hits its 10th anniversary edition from June 11 to 14, 2026, at Messe Berlin. The event is one of the largest cannabis gatherings in the world, with more than 75,000 attendees and 500+ exhibitors expected across four days. Thursday is dedicated to B2B trade and conference programming. Friday through Sunday are open to the public for the festival.

From cultural celebration to commercial powerhouse

Mary Jane started a decade ago as a cultural festival. Germany’s legalization changed what the event is. The expo floor now combines serious B2B exhibitors with the consumer-facing festival programming that built the brand. International cultivation operators, vape and cartridge manufacturers, medical cannabis companies, and ancillary service providers all use the trade days to launch German market strategies. The festival side keeps the original community DNA intact.

The structure is the genuinely interesting part. June 11 is a quiet B2B day, 10 a.m. to 6 p.m., trade pros only, with conference panels and networking. June 12 through 14, the doors open for the public festival. Live music across multiple stages. A “care culture” infrastructure with awareness teams and free water stations. An alcohol-free environment, with smoking permitted only in designated outdoor areas. Closer to a Berlin nightlife event than a US trade conference.

Mary Jane Berlin 2026, by the numbers

500+

International exhibitors

Two builders, one stage

The B2B day’s centerpiece is a live taping of the Mary Jane Podcast on the Studio Stage. The format is “CEO Insights.” The lineup includes Josh Kesselman, founder of RAW Rolling Papers and publisher of High Times, in conversation with Duc Anh Dang, co-founder of Mary Jane Berlin.

The pairing is the talk worth getting in early for. Two completely different paths to building enduring cannabis brands at scale. Kesselman turned a rolling paper company into one of the most recognizable names in global cannabis culture. Dang turned a community festival into one of the biggest cannabis events in the world. Both built it without a roadmap. Both did it before legalization made any of it easy.

If you’re attending and want to connect, the conference floor is the place to find him. The Studio Stage is the place to find Josh Kesselman.

The festival side

The public festival days bring a stacked music lineup including Marteria, Samy Deluxe, Marvin Game, Antifuchs, Eightfour, Herzog, Majan, WizTheMc and Haiyti, plus Berlin underground acts across multiple stages. The conference adds three programming streams: a Studio Stage for talks and live podcasts, a Masterclass Stage for 90-minute deep dives on practical topics, and an Immersive Stage for guided meditation, soundbath, breathwork and mindful pauses.

It’s the format US events have been talking about for years. Mary Jane just keeps doing it.
