  1. a Polysubstance-related disorders group included the following sub-groups: cannabis +other drugs-related disorders (n = 2,025), cannabis +alcohol-related disorders (n = 1,511), other drugs +alcohol-related disorders (n = 3,957), cannabis +other drugs +alcohol-related disorders (n = 2,908)
  2. b Chronic physical illnesses included: renal failure, cerebrovascular illnesses, neurological illnesses, hypothyroidism, fluid electrolyte illnesses, obesity, any tumor without metastasis, metastatic cancer, chronic pulmonary illnesses, diabetes complicated and uncomplicated, congestive heart failure, peripheral vascular illnesses, valvular illnesses, myocardial infarction, hypertension, pulmonary circulation illnesses, blood loss anemia, ulcer illnesses, liver illnesses, AIDS/HIV, rheumatoid arthritis/collagen vascular illnesses, coagulopathy, weight loss, paralysis, deficiency anemia
  3. c Missing address or living in an area where index assignment is not feasible. An index cannot usually be assigned to residents of nursing home or homeless individuals
  4. d Usual GP (proxy for “patient family physician”) was defined as having at least two consultations with the same GP or with at least two GP working in the same family medicine group. Usual psychiatrist was defined as one that followed any patient in ambulatory care at least twice. Alternatively, individuals who made only one outpatient consultation with a psychiatrist had to have consulted their GP at least twice, which was considered a proxy for collaborative care. The Usual Provider Continuity Index describes the proportion of visits to the GP and psychiatrist most frequently used of all GP and psychiatrists consulted in ambulatory care
  5. e Services offered in addiction treatment centers included: medical activities (e.g. substitution treatment), specialized services for pathological gambling (e.g. rehabilitation), external services for pathological gambling (e.g. family support services), specialized addiction services (alcohol, drugs; e.g. detoxification treatment); external addiction services (e.g. reintegration), and brief treatment in addiction intervention units
