Editorial for special issue: Vulnerable Groups: Addiction Research, Policy and Practice

Alcohol, drug and tobacco problems are common across the globe.

We defined vulnerable groups here as communities who are marginalised or excluded from mainstream healthcare and other services due to geographical and demographic factors and/or socioeconomic status.
