The Centre for Addiction and Mental Health is a psychiatric teaching hospital located in Toronto and ten community locations throughout the province of Ontario, Canada. The hospital was formed in 1998 from the amalgamation of four separate institutions – the Queen Street Mental Health Centre, the Clarke Institute of Psychiatry, the Addiction Research Foundation, and the Donwood Institute. It is Canada's largest mental health teaching hospital, and the only stand-alone psychiatric emergency department in Ontario. CAMH has 90 distinct clinical services across inpatient, outpatient, day treatment, and partial hospitalization models. CAMH has been the site of major advancements in psychiatric research, including the discovery of the Dopamine receptor D2.
Cocaine Anonymous (CA) is a twelve-step program formed in 1982 for people who seek recovery from drug addiction. It is patterned very closely after Alcoholics Anonymous, although the two groups are unaffiliated. While many CA members have been addicted to cocaine, crack, speed or similar substances, identifying specifically as a cocaine addict is not required.

Drug addiction recovery groups are voluntary associations of people who share a common desire to overcome drug addiction. Different groups use different methods, ranging from completely secular to explicitly spiritual. Some programs may advocate a reduction in the use of illegal drugs rather than outright abstention, although this is typically not a sustainable treatment plan in the long term. One survey of members found active involvement in any addiction recovery group correlates with higher chances of maintaining sobriety. The survey found group participation increased when the individual members' beliefs matched those of their primary support group. Analysis of the survey results found a significant positive correlation between the religiosity of members and their participation in twelve-step addiction recovery groups and SMART Recovery, although the correlation factor was three times smaller for SMART Recovery than for the twelve-step addiction recovery groups. Religiosity was inversely related to participation in Secular Organizations for Sobriety.
