In Portugal drug possession, use are illegal. They aren't criminal but are illegal and carry penalties at special drug courts which give less protect to defendents.
Also, Vancouver's downtown core hardly had any families and things families need simply aren't available downtown.
They shouldn't be all that different. Vancouver (well, British Columbia) has tried to model its decriminalization efforts after Portugal's.
That decriminalization hasn't even been around for more than a handful of months, though, so it seems rather early for Vancouver to also be having doubts. Nobody was expecting things to change overnight; Health Canada allowed until 2026 to prove the model.
In Portugal drug possession, use are not criminal but they are illegal and carry penalties.
In BC possession for personal use is legal. There are no penalties.
That is not the same.
