The document discusses harm reduction as an alternative approach to abstinence-based treatment for substance abuse. It notes that harm reduction aims to improve quality of life for individuals who continue substance use by providing services, while abstinence-based treatment requires discontinuing all substance use. Both approaches can connect individuals to social services and reduce harms of substance abuse, but harm reduction may be more beneficial for some as it does not require immediate abstinence. The major difference between the approaches is the demand for abstinence in treatment.
