I was in Lisbon yesterday where we were literally chased by drug dealers because they asked me if I wanted to buy and I said "no thanks"
I try avoid the city, obviously it's localized to a few parts, but I'd also add, not really, it's kinda spreading out to all over the city
There's an entire "crackolandia" now near Campo de Ourique if you drive off from there to the highway, full of crack zombies
Police generally do nothing
Odd about that part btw is it's literally a mix of I think social housing and crack addicts, so you see families having lunch outside while people a few meters away are shooting up
And that part isn't even the worst
