Understanding the causes of drug and alcohol addiction in India is the first step toward prevention and recovery. This guide explores why substance abuse in India has become a growing public health concern, breaking down the psychological, emotional, and social factors that pull people into dependency. Learn how stress, anxiety, and poor mental health trigger alcohol and drug addiction, and why easy availability of substances, low cost, surrogate alcohol promotions, and peer pressure make young people especially vulnerable. We also examine the role of digital media influence, childhood trauma, and family issues in fuelling addiction across the country. Backed by data from the Ministry of Social Justice and Empowerment and WHO, this article helps families, students, and caregivers recognise the warning signs early and understand the root causes of substance dependence.
