Calibrated prohibition reduces drug harms

The article argues that prohibition, if implemented with calibrated, evidence‑based enforcement and complementary interventions, can suppress consumption and associated harms despite demand inelasticity. It further contends that legalization-plus-excise-tax routinely raises availability and consumption in practice, undermining the simple economic claim that taxes simply substitute for enforcement. — This reframes the legalization-versus-prohibition debate by making enforcement design — not just the binary choice — the central policy variable with measurable public‑health and fiscal consequences.
