The International Cannabis Business Conference is Europe's largest and longest-running cannabis B2B event, and the 2027 edition returns to the Estrel Berlin hotel April 13 to 15, 2027. This is the room where the European industry actually gets built: roughly 7,500-plus attendees from more than 80 countries, 500-plus exhibitors and sponsors, and over 25,000 square meters of exhibition space, all pointed at the fastest-moving cannabis market on the planet right now — Germany.
Since Germany reworked its cannabis laws, both the medical and adult-use sides of its market have been expanding at a pace the American industry should be watching closely, and ICBC Berlin sits at the center of that growth. Cultivators, distributors, retailers, pharmacies, and ancillary companies use these three days for the unglamorous work that moves markets: networking, deal-making, and figuring out who actually supplies whom across a continent's worth of regulatory borders.
The access model says a lot about where the German scene is heading. Tickets go on sale in the fall, and ICBC offers free admission to qualifying categories — more than 300 German cannabis social clubs, 150-plus European grow shops, and over 500 German cannabis pharmacies. That's a conference deliberately wiring together the cultivation, retail, and community layers of a young market, and it's why the Estrel fills up every spring.
For a California audience, Berlin is worth the flight for one reason: perspective. The US market matured behind state lines; Europe is building cross-border from day one, with Germany as the anchor. The brands, genetics, and infrastructure players you meet at ICBC are the ones that will define how cannabis trades internationally over the next decade — and plenty of them are hunting for American partners.
If your 2027 plans include Europe at all, this is the anchor date to build the trip around. Registration and ticket notifications run through internationalcbc.com, and signing up early matters: the free-admission categories and the exhibitor floor both fill well before doors.
