Legalization eased legal fears, but not interest in cannabis

Background: The illegal status of recreational cannabis (RC) is often considered a barrier to its use. RC was partially legalized in Germany in 2024. This study investigated whether attitudes towards cannabis were different in patients surveyed after recreational cannabis legalization (RCL), compared with patients surveyed before RCL. Method: In 2022 (pre-RCL) and 2024/2025 (post-RCL), patients without psychosis and without substance use disorders from in-patient and day clinic wards of a psychiatric university hospital were interviewed using a standardized questionnaire. Results: Included were n = 143 patients pre-RCL and n = 117 post-RCL, with 84% presenting with affective disorders. Only 11.2% in the pre-RCL group, and 1.7% in the post-RCL group indicated the illegal status of RC as the main reason for cannabis abstinence. Attitudes towards cannabis with regard to health concerns, social distance, general rejection of (illicit) drugs, effects of drug education, or observation of negative consequences in others were not statistically significantly different between groups. There was a marked and statistically significant reduction in fear of being investigated by the police because of RC consumption. The suggestion to buy cannabis for personal use in specialized shops was completely rejected by 58.7% of the pre-RCL and by 71.8% of the post-RCL group. Conclusions: Compared with pre-RCL data, concerns about negative legal consequences of RC use were lower during the first year post-RCL, but readiness to legally obtain recreational cannabis was not increased. There were no indications that other attitudes about cannabis were affected in the short term.
