Acces Interdit: publications research and advice

About Acces Interdit: publications research and advice

Since 1990 we study the cannabis market. For universities, ministries, local governments and institutions for health care and justice. We interviewed hundreds of consumers, producers, distributors and others in the cannabis industry, but also policemen, politicians, mayors and many others. It brought us valuable knowledge about a hidden sector.

Our activities in the Netherlands and worldwide gave us a solid network. We use it to get our information and to connect people using different viewpoints on this matter. Many politicians consult us, but also media, mayors, investors and quite some stakeholders in the cannabis industry.

With articles, books and presentations about our research and experiences in the cannabis industry we inform the world about what we learned last decades.
