Oh, the anti-rave laws were a textbook example of unintended consequences: they made it legally fraught to make life-saving harm minimization accessible, since the way the law was drafted, that'd confirm a rave host was "aware of the presence" of drugs—an element of the crime. Likely caused a net increase in drug-overdose deaths. Poorly-thought out, asymmetric incentives: strongly disincentivizes helping people not-die, while failing at disincentivizing creating an environment for easy access to hard drugs.
