Decriminalizing cannabis doesn't lead to more widespread use, according to a study comparing cannabis users in two similar cities with opposing cannabis policies — Amsterdam, the Netherlands (decriminalization), and San Francisco, California (criminalization). The study compared age at onset, regular and maximum use, frequency and quantity of use over time, intensity and duration of intoxication, career use patterns, and other drug use. No evidence was found to support claims that criminalization reduces use or that decriminalization increases use.
In the context of a fast changing and well documented market in legal highs, the case of khat (Catha edulis) provides an interesting anomaly. It is first of all a plant-based substance that undergoes minimal transformation or processing in the journey from farm to market. Secondly, khat has been consumed for hundreds if not thousands of years in the highlands of Eastern Africa and Southern Arabia. In European countries, khat use was first observed during the 1980s, but has only attracted wider attention in recent years.
As the world prepares for the 2016 Special Session of the United Nations General Assembly on the World Drug Problem (UNGASS 2016), an increasing number of countries around the world now find the regime’s emphasis on punitive approaches to illicit drugs to be problematic and are asking for reform. In this moment of global disagreement, the Brookings project on Improving Global Drug Policy provides a unique comparative evaluation of the effectiveness and costs of international counternarcotics policies and best approaches to reform.
