Mary Jane Berlin brings a cannabis expo and a music festival together at Messe Berlin from June 3–6, 2027. It opens with a B2B trade visitor day on Thursday, then goes public for three days of expo and festival from Friday through Sunday. The organizers call 2027 Season 2, the start of a new chapter after the event's first 10 years, and bill Mary Jane as the world's largest cannabis event.
What's inside
More than 500 exhibitors set up on the expo floor, from established brands to newer companies, covering vaporizers, cultivation, medical applications, cosmetics and lifestyle products. A conference runs alongside it with keynotes and panels on trends, legal developments and business opportunities. An exclusive B2B lounge gives entrepreneurs, investors and founders a place to meet away from the aisles.
When the halls close, the party keeps going. The festival runs past the fair's closing time on Friday and Saturday, with live music, food trucks and outdoor areas for the industry people, artists and fans who stick around.
Hours by day
Thursday, June 3 is the B2B day, open 11:00 AM–6:00 PM with no festival. Friday, June 4 and Saturday, June 5 run 11:00 AM–8:00 PM, with the festival going until 10:00 PM. Sunday, June 6 runs 11:00 AM–6:00 PM, and the festival wraps at 6:00 PM too.
Entry rules
Mary Jane Berlin is strictly 18+, and coming with a parent or another adult doesn't change that. Bring valid photo ID. Smoking is banned inside the halls and allowed in the outdoor area. The event is alcohol-free, possession or use of narcotics under German drug law (BtMG) isn't permitted, and heavily intoxicated visitors won't be let in.
Security runs bag checks and waits are expected, so arrive early. Bags bigger than A4, backpacks and suitcases stay home, along with glass bottles, weapons, fireworks, drones, scooters, bikes and animals other than service animals. PET bottles and cartons up to 1 liter are fine, two per person, and refill stations are on site. A ticket on your phone is all you need at the door.
Tickets
Tickets are on sale through the official Mary Jane Berlin ticket shop, with prices rising across four sales phases. In the opening Super Early Bird phase, festival day tickets cost €25 for Friday, €35 for Saturday and €20 for Sunday. The three-day Friday–Sunday ticket is €70, and the Golden Ticket, which adds VIP access, is €110.
Business tickets cover the trade day. Business Thursday, which is conference only, costs €190. Business plus Weekend covers Thursday through Sunday for €260, and Business plus Golden adds VIP for €280. Each later phase costs more, so earlier buyers pay less.
Getting there
Messe Berlin is at Hammarskjöldplatz, and Mary Jane uses the North Entrance. Take the U2 to Theodor-Heuss-Platz or Kaiserdamm, or the S-Bahn (S1, S41, S42, S45, S46) to Messe Nord/ICC. Buses also stop near Theodor-Heuss-Platz and at the exhibition grounds. Parking at P1 and P2 in front of the North Entrance is free, but spaces go fast, so public transport is the move.
The venue is ground level and barrier-free, and companions of visitors with a B, Bl, GL, aG or H mark on their disability pass get in free.
More Berlin and Europe
