Editor's Notes
The issue of drugs legalisation continues unabated. Reviewing contents of Addiction in 2013 I am struck by a truth about human behaviour: the harder it is for people to do things, the less they do them. But do we care enough to put the necessary resources into enforcement and deal with the consequences? If it were illegal to sell alcohol to someone without a 'responsible drinker' licence, or tobacco to someone lacking proof of age, the effect on population health would be substantial. But such a plan would be crazy, surely...? The pages of Addiction in 2014 will help answer this question and others like it.
