Portugal

“Prohibition—this policy I have traced across continents and across a century—consists of endlessly spreading downward spirals. People get addicted so we humiliate and shame them until they become more addicted. They then have to feed their habit by persuading more people to buy the drugs from them and become addicted in turn. Then those people need to be humiliated and shamed. And so it goes, on and on. But in Portugal after the drug war, the state helped people to get better, and then those people helped more people to get better, and then they helped still more people to get better—and so the downward spiral of the drug war has been replaced by a healing ripple that spreads slowly out across the society.”
― Johann Hari, Chasing the Scream: The First and Last Days of the War on Drugs
