Der Krieg gegen sichere Drogen

This has been studied:

Question : What is the association of the adoption of the safer supply policy and subsequent decriminalization of drug possession in British Columbia, Canada, with opioid overdose outcomes?

Findings : Using the synthetic difference-in-differences method, this cohort study found that the safer opioid policy was associated with a statistically significant increase in opioid overdose hospitalizations but no change in overdose deaths; the addition of drug possession decriminalization was associated with a further increase in overdose hospitalizations.

Meaning : Neither the safer opioid supply policy nor the decriminalization of drug possession appeared to mitigate the opioid crisis, and both were associated with an increase in opioid overdose hospitalizations.
