Abstract
This chapter covers the application of the law surrounding incidents that involve alcohol, drugs, and substance use. It cites that the health and safety of all persons present must be considered due to the potential for injury. Moreover, the Police Constable Degree Apprenticeship (PCDA), the Degree Holder Entry Programme (DHEP), and pre-join programmes often also provide an introduction to the wider issues surrounding alcohol and other forms of drug and substance use. The chapter mentions how alcohol is also a problem for a significant minority of young people. Meanwhile, drug legislation has been carefully worded so that it would prosecute users and people involved in the drug supply.
