Rise in Cannabis Consumption Among Young Adults Following Legalization

A recent study conducted by the Federal Institute for Public Health (BIÖG) reveals a significant increase in cannabis use among young adults aged 18 to 25 since the partial legalization of the drug in Germany. The findings indicate a notable trend, with consumption rates for this age group rising to 31.6% in 2025, up from 20.6% in 2015.

The increase is particularly pronounced among young men, while women also show an upward trend, albeit at a lower rate. The study reports that the percentage of young women who consumed cannabis within the past year increased from 9.7% in 2015 to 18.5% in 2025. The BIÖG has emphasized the importance of monitoring this trend closely, as cannabis can adversely affect the health and brain development of young individuals, potentially leading to memory and concentration issues.

Interestingly, the research indicates that there has been little change in cannabis consumption among adolescents aged 12 to 17. The data shows that only 4.6% of girls and 7.2% of boys in this age group reported using cannabis at least once in the past year, with no statistically significant variations compared to previous years. However, a slight decline in usage among male adolescents was observed, with the figure dropping from 10.8% in 2019 to the current 7.2%.

The legalization of cannabis in Germany occurred on April 1, 2024, allowing adults aged 18 and older to possess limited amounts of the substance for personal use, grow cannabis plants at home, and consume it under regulated conditions. This legislative change was initiated by the coalition government comprising the Social Democratic Party (SPD), the Greens, and the Free Democratic Party (FDP).

The BIÖG's study involved a representative sample of 7,001 adolescents and young adults aged 12 to 25 surveyed between April and July 2025. These findings highlight the ongoing shifts in drug consumption patterns following policy changes, emphasizing the need for continued public health initiatives and education regarding the implications of cannabis use.
