Use may be tolerated, but supplying narcotics is not. the national police force has not retreated from the so called war on drugs. is drug trafficking a big problem here? yes, this is a big problem and a big concern for us, because we know that the traffic dealers are very well organised. so are you winning? well, it s not a question of winning or losing, because i think it s an international problem and no one wins this fight. so it s a daily fight that you do every day, trying to do your best. more than 20 years after portugal decriminalised drug use, no one says it s a magic bullet the problem is complex, every country is different. but the fact remains far fewer drug users are dying here than are dying in scotland. james cook, bbc news, lisbon.
