Oh here we go, on the defensive straight away.Where was that? In the Algarve? Very low crime rates in Portugal as a whole. Lived here a couple of years now and had absolutely no bother. Had far worse living in the U.K.
Also as per OP, drugs are not legal. Any visitor into that sort of caper do not buy off the numerous street ‘dealers’ in Lisbon/Porto/Faro etc.
