A review of drug law enforcement in New South Wales considers the extent of the problem, police strategy, drug user diversion programs, drug-related crime, and police recommendations for improved drug law enforcement. Another paper discusses the importance of distinguishing between drug categories and between users, addicts, and suppliers when determining penalties. Telephone tapping and the warrantless entry of premises are opposed, but greater access to suspects' financial records is supported. A paper reviews the history of opiate dependence, argues for the importance of treatment in prevention, presents the pros and cons of methadone maintenance, and proposes more spending for drug treatment. The final paper describes drug-crime research subjects and methodologies used by the New South Wales Bureau of Crime Statistics and Research, current research developments, and the interaction between research and drug enforcement policy.
