Contributing author (ongoing), CLRNN Project 4: The Regulation of Drugs. The project will focus on three severable, though inter-related, problematic areas in the practical regulation of people who use controlled drugs: (1) pre-trial matters (i.e., depenalisation, diversion, or prosecution); (2) post-trial matters (i.e., sentencing); and (3) the ‘special case’ of medical cannabis exemptions.
