Cali Island Brings California Culture To The Heart Of Mary Jane Berlin 2026

As Mary Jane Berlin continues its rise as the largest cannabis gathering in the world, a new destination is emerging inside the expo that aims to capture something bigger than products, booths, or business deals. It’s about culture.

Welcome to Cali Island, an ambitious experiential hub bringing together some of the most recognizable names in cannabis, lifestyle, and underground culture for a multi-day activation designed to transport attendees from Berlin to California—without ever leaving the Messe grounds.

Located inside Mary Jane Berlin, Cali Island serves as a meeting point for brands, creators, entrepreneurs, and enthusiasts looking to connect through shared experiences rather than traditional trade show interactions. Throughout the event, attendees will find a carefully curated mix of brand activations, networking opportunities, entertainment, and exclusive after-hours programming that extends far beyond the convention floor.

The concept reflects a broader shift taking place across the global cannabis industry. As markets mature, culture has become just as important as commerce. Cali Island embraces that reality by creating an environment where authentic relationships can develop naturally.

A Gathering Built By The Culture

A Gathering Built By The Culture

The activation features a diverse lineup of participating brands and organizations including OnlyGrams, TERPHOUSE, Sherbinskis, Royal Blunts, BOUTIQ, Kushie Brand, Exoticus, Jack Herer, Top Shelf Cultivation, Sunset Exotics, Sluggers Hit, Green Rush Nation, Nothing But Fire, Parachute, SMOKERZ Berlin, STONERZ e.V., Xaler League, and many others.

Media partner Honeysuckle will be on-site throughout the week documenting the people, conversations, and collaborations shaping the next chapter of international cannabis culture.

Rather than focusing solely on product showcases, Cali Island is designed to encourage interaction between founders, cultivators, creators, retailers, and consumers from across Europe and North America.

Smokerz League Opens The After Hours Experience

On June 11, Cali Island launches its official After Hours series with Smokers League, presented alongside SMOKERZ Berlin e.V.

The networking-focused gathering is designed to give attendees an opportunity to connect away from the noise and pace of the exhibition floor. Brands, creators, and cultural leaders will come together for an evening centered on conversation, collaboration, and community.

The event reflects Berlin’s growing role as a crossroads for the global cannabis movement, where emerging European markets increasingly intersect with established California operators and legacy culture figures.

High Dining Elevates Networking

One of the most anticipated experiences during the week is HIGH DINING – An Elevated Cannabis Experience, presented by OnlyGrams and TERPHOUSE.

Set against Berlin’s skyline, the private dinner brings together industry executives, innovators, tastemakers, and invited guests for an evening that combines fine dining, curated hospitality, and high-level networking.

Part of the broader Cali Island concept, High Dining represents the growing demand for premium experiences that blend luxury hospitality with cannabis culture. The event offers guests an opportunity to build meaningful relationships in a setting far removed from traditional conference rooms and convention halls.

Fight Night Meets Cannabis Culture

The weekend’s programming continues with UFC Freedom 250 Fight Night, presented by Swizz Boyzz and Cali Island.

Created in partnership with SMOKERZ Berlin e.V., the live viewing experience brings fight fans together for a night of sports, conversation, and social club energy. The event highlights another key element of the Cali Island vision: creating cultural touchpoints that resonate beyond cannabis itself.

By combining entertainment, hospitality, networking, and lifestyle experiences, the activation seeks to create an environment where attendees can build lasting relationships while enjoying some of the most anticipated moments of Mary Jane weekend.

California Energy, Global Audience

What makes Cali Island particularly notable is its timing.

As Germany’s legal market continues to evolve and European cannabis culture expands, international brands are increasingly looking for ways to connect with consumers and operators beyond traditional retail channels. California remains one of the industry’s most influential cultural exporters, and Cali Island serves as a bridge between those worlds.

At a show expected to attract tens of thousands of attendees from around the globe, the activation offers a glimpse into what the future of cannabis events may look like: less focused on transactions, more focused on experiences.

For one week in Berlin, California culture has found a new home.

And for many attending Mary Jane 2026, that island may become one of the most talked-about destinations of the entire event.
