Cannabis remains the most commonly used illicit substance world-wide, with international estimates indicating that 2.8%-4.5% of the global population use cannabis each year. This prevalence rate has not changed substantially in the past decade and there is no indication that it will do so in the next decade. In line with this, many prominent organizations and individuals have acknowledged that the "war on drugs" has failed and are now calling for a rethink on drug-related policy and legal frameworks. With a growing number of jurisdictions across the world heeding this call and introducing legislation to decriminalize or legalize cannabis use, it is essential that any changes to legal frameworks and public health policies are based on the best available scientific evidence. To facilitate the adoption of an evidence-based approach to cannabis policy, the aim of this Research Topic was to gather a comprehensive body of research to clarify the current state of evidence relating to cannabis use. |
