Introduction

Substance abuse, or the harmful or hazardous use of psychoactive substances including alcohol and illicit drugs, is a growing public health concern. It poses substantial medical, social, and economic burdens on individuals, families, and societies. According to WHO, substance abuse contributes significantly to the global burden of disease, mental disorders, and premature deaths.

In India, substance abuse is not only a medical issue but also a deeply rooted socio-cultural problem. Understanding its community dimensions is essential for planning effective public health responses.

Trends: Substance abuse is increasingly prevalent among adolescents, women, and rural populations.
Demographic Patterns:
- Age: Peak initiation occurs in late adolescence to early adulthood (15–24 years).
