Hash Marihuana & Hemp Museum

Oudezijds Achterburgwal 148 — in the heart of the Red Light District, along one of Amsterdam’s oldest canals.

Founded by Ben Dronkers (the creator of Sensi Seeds), the Hash Marihuana & Hemp Museum is one of the most comprehensive cannabis collections on Earth. With over 12,000 objects spanning centuries, the museum traces the plant’s journey from ancient medicine and industrial crop to counterculture symbol and modern commodity.

Highlights of the collection:

• An 1836 hemp Bible — printed on hemp paper, demonstrating the plant’s pre-prohibition role in everyday life
• Antique smoking paraphernalia from Asia, Africa, and the Middle East, showing cannabis consumption traditions across cultures
• Industrial hemp exhibits covering rope-making, textile production, and the plant’s role in maritime history (Dutch ship sails were made from hemp)
• A living cannabis garden — real cannabis plants growing under lights inside the museum. One of the few places in the world where visitors can legally observe live cannabis cultivation up close
• Cannabis art gallery — rotating exhibitions of cannabis-inspired artwork and historical illustrations

Practical information: Admission €9–10. Open daily 10:00–19:00. Plan 60–90 minutes for a thorough visit. Tickets can be purchased online or at the door. The museum is compact but densely packed with material — take your time.

Cannabis College

Oudezijds Achterburgwal 124 — steps from the Hash Museum, on the same canal.

Cannabis College is not a school in the traditional sense — it is a free, donation-based education center that has been operating since 1998. The space is part museum, part classroom, part social experiment in cannabis normalization.

What you will find inside:

• Volcano vaporizer lounge — Bring your own cannabis (BYOC) and use the house Volcano vaporizers. This is a social space where visitors from around the world sit together and discuss cannabis culture with the staff and each other
• Educational exhibits — Displays covering cannabis botany, the endocannabinoid system, Dutch law, and the plant’s global history
• Microscopes — Examine trichomes, the tiny resin glands on cannabis flowers that contain cannabinoids and terpenes. Seeing trichomes under magnification helps visitors understand why different strains look and smell different
• Grow room tour — A small, active cannabis grow operation that you can tour for a suggested €3 donation. See how cannabis is cultivated from seed to harvest in a controlled indoor environment

Practical information: Free admission (donations appreciated). Open daily 11:00–19:00. The staff are passionate, knowledgeable, and happy to spend time explaining cannabis science and culture to visitors of all experience levels.

The Jack Herer Connection

Jack Herer (1939–2010) was an American cannabis activist and author of The Emperor Wears No Clothes, a book that documented hemp’s industrial history and argued for cannabis legalization. Herer spent significant time in Amsterdam, where his ideas found a receptive audience and his name was given to one of the most famous cannabis strains ever created.

The Jack Herer strain, bred by Sensi Seeds and released in 1994, was named in his honor. It remains a coffeeshop staple. Herer’s legacy lives on in both the Hash Museum (which features exhibits on hemp activism) and Cannabis College (which embodies his belief that education is the path to normalization).

Both institutions carry forward the philosophy that cannabis education — honest, science-based, free from stigma — is essential for responsible policy and consumption. In a city where coffeeshops have been open for half a century, these spaces remind visitors that cannabis is not just a product but a plant with a history as deep and complex as any crop humanity has cultivated.

Planning Your Visit

Both venues are in the Red Light District, easily reached from Amsterdam Centraal Station (10-minute walk) or by tram to Dam Square. A combined visit takes 2–3 hours. Suggested approach:

1. Start at the Hash Museum (10:00 opening) for historical context
2. Walk to Cannabis College (opens 11:00) for hands-on education and the grow room
3. Visit a coffeeshop in the Centrum afterward to apply what you have learned

Both venues are family-appropriate in their educational content, though Cannabis College’s vaporizer lounge is for adults only.
