This study analyzes the urgency of the role of families in addressing narcotics abuse crimes in Indonesia from a legal perspective. Narcotics abuse has evolved into a complex issue affecting not only individual offenders but also social stability, public health, and national security. Although Indonesia has implemented strict regulations under Law Number 35 of 2009 concerning Narcotics and supporting legal instruments, narcotics abuse cases continue to increase in both scale and complexity. This research employs normative legal methods using statutory, conceptual, and case approaches with secondary legal materials. The findings show that Indonesian narcotics law adopts a balanced approach between punishment and rehabilitation, emphasizing the importance of community and family participation. Families are legally required to report narcotics addicts for rehabilitation purposes, as regulated in Article 134 of Law Number 35 of 2009, supported by Government Regulation Number 25 of 2011 and related legal instruments. However, this obligation raises issues related to criminal culpability, legal awareness, and social stigma. The study concludes that family involvement is crucial as the first line of prevention and rehabilitation support. Strengthening legal education, public awareness, and rehabilitation access is essential to ensure effective implementation of narcotics law and reduce drug abuse in Indonesia.
