Transform has great coverage: Another UN agency savages the drug war
Here’s the key quote:
“[Drug control efforts] have had harmful collateral consequences: creating a criminal black market; fuelling corruption, violence, and instability; threatening public health and safety; generating large-scale human rights abuses, including abusive and inhumane punishments; and discrimination and marginalization of people who use drugs, indigenous peoples, women, and youth” â€” The United Nations Development Programme
Wow! Really powerful stuff.
And they keep going, talking about the impact of drug policies on the formal economy, on human rights, on gender, on the environment, and on indigenous peoples, and they argue that “new approaches are both urgent and necessary.”
