A significant decrease in cannabis-related offenses has been observed in Germany following the introduction of partial legalization measures. Data from the police crime statistics, detailed in an interim report from the EKOCAN project – which is evaluating the impact of the Consumption Cannabis Act (KCanG) – indicates approximately 100,000 fewer criminal proceedings compared to the previous year. The change in legislation has primarily benefited individuals engaging in minor consumption, as the possession of small amounts for personal use is now legal.
The evaluation suggests the number of consumers has remained relatively stable. An estimated 5.3 million adults in Germany consumed cannabis in 2024. Medical cannabis accounted for roughly 12 to 14 percent of total consumption, while cannabis cultivation associations contributed less than 0.1 percent. Jakob Manthey, who coordinates the project, notes that the full implications for public health are not yet entirely clear. He has highlighted the limited number of cultivation associations as a potential challenge, advocating for simplified procedures for their licensing and operation.
Daniel Kotz, leading the project from Düsseldorf, stated that the downward trend in cannabis consumption among young people persists even after legalization. However, approximately one-tenth of young consumers still engage in risky consumption patterns, which heighten the likelihood of health problems. A final report from the EKOCAN project is expected in April 2028.
