"The EMCDDA’s cannabis monograph addresses one basic question. How can I find quality information on cannabis, amid all the bias and opinion? The monograph is divided into two volumes. The first volume centres on political, legislative, commercial and social developments relating to cannabis. Its core audience thus comprises policymakers, sociologists, historians, journalists and those involved in enforcement. The second volume is targeted at drugs professionals working in the fields of treatment, prevention and healthcare."
