The situation is not perfect, and will never be, but is a LOT better than before! Portugal is a lot safer. The crime that you talk about is probably not drug related and probably not local people. Just read the news. Did you find any place to sell used things? No except for gold.
And if you find someone "drunk" at 9am you bet he is drunk lol "evita a ressaca, mantente bebado" something like "void hangover, stay drunk" every village has a chronic drunk! Maybe now the biggest problem is alcool, not heavy drugs. Why do you think police stop people at 9am and force them to do an alcohol test? They are drinking since 6am!
Regarding your ISP. Your target is people in a rural area? In one of the most less dense population area in Portugal? I will be waiting for the pricing. Good Luck.
