The UK has the highest rate of cannabis use among young people worldwide. Dr. Alan Leshner, Director of the National Institute of Drug Abuse reports, "Every year more than 100,000 people, most of them adolescents, seek treatment for their inability to control their marijuana use." According to the Scottish Drug Misuse Statistics in Scotland 2002, 51% of individuals under 20 years have used cannabis. Cannabis use is not limited to youth; it is also the single-most used illicit drug among adults. Because of their widespread negative impact, illicit drugs have become a focus of the agenda of the English Parliament and there is ongoing debate on how to combat this problem. As the research assistant of Michael Matheson (MSP), the author compiled this report to gather information on cannabis and to assess approaches that would form the most effective cannabis policy. This research explores whether or not the recent change toward decriminalization is adequate, or if it needs further revising.
