The Swiss experiment was a massive disaster. Wish we had never done it, and it certainly took a few decades to clean up its effect on parts of Zürich. It attracted junkies from all over Europe and with it brought crime and violence. I spent a few years going to primary school near the epicenter of it in the late 90s. The number of times I saw people shooting up in broad daylight right in front of my school… is shocking. Even more shocking were the parks littered in used needles. Parks kids would play in… can you imagine what can happen? They'd be cleaned up on the regular, and staff would literally have bags full of used needles!
It was pretty traumatic to see, not that I really understood it as a kid.
It was way worse than the streets of San Francisco today, which are an absolute disaster too!
Good riddance, getting rid of that "treatment" was the best thing we ever did.
