About Mary Jane Berlin
Mary Jane Berlin is Europe's largest cannabis event by attendance. The 2026 edition, marking the event's 10th anniversary, runs June 11–14 at Messe Berlin — one of Germany's most prominent convention venues. The event expects 65,000+ visitors and 500+ exhibitors.
Berlin's official tourism board officially promotes Mary Jane Berlin as the "world's largest cannabis event," a claim made possible by Germany's adult-use cannabis legalization that took effect in April 2024.
Four-Day Format
- Day 1 (June 11): B2B-only programming, focused on industry attendees and exhibitors
- Days 2–4 (June 12–14): Open as a consumer festival with music, education, brand activations, and product demonstrations
What to Expect
- 500+ exhibitors spanning the European cannabis supply chain
- Educational programming on cultivation, products, regulation, and culture
- Brand activations from major European cannabis and cannabis-adjacent brands
- Live music and entertainment creating a true festival atmosphere
- US influencer presence — American cannabis personalities are confirmed speakers
- Cannabis consumption permitted on-site (subject to German regulations)
For US Professionals
Mary Jane Berlin's relevance for US business professionals is more limited than B2B-focused events like ICBC Berlin or Cannabis Europa London — it's primarily a consumer festival. However, for brand visibility, market intelligence, and understanding European cannabis culture firsthand, it has no equal in Europe. The 65,000-attendee scale provides unmatched opportunities to observe consumer preferences, packaging trends, and brand positioning in Europe's fastest-growing legal cannabis market.
Why Berlin?
Germany's 2024 adult-use legalization made Berlin the natural epicenter of the European cannabis events circuit. Three of Europe's five largest cannabis events are now in Germany — Mary Jane Berlin, ICBC Berlin, and others — reflecting the country's strategic position as both a major consumer market and a regulatory pioneer for the rest of Europe.
