Substance abuse and drug trafficking have emerged as serious challenges in India, affecting public health, social stability, economic productivity, and national security. India’s geographical location between the Golden Crescent, comprising Afghanistan, Iran, and Pakistan, and the Golden Triangle, consisting of Myanmar, Laos, and Thailand, makes it highly vulnerable to illegal drug trafficking. This strategic position has turned the country into both a transit route and a consumer market for narcotic substances. Over the years, the problem has expanded from border regions to metropolitan cities, towns, and rural areas, creating a wide network of addiction and criminal activity. The extent of substance abuse in India can be understood from the increasing use of alcohol, tobacco, cannabis, opioids, heroin, cocaine, sedatives, inhalants, and synthetic drugs. Alcohol remains one of the most commonly abused substances. It is consumed in both urban and rural areas and often leads to dependency, family conflicts, accidents, and chronic diseases. Tobacco use in smoking and smokeless forms is also widespread and is responsible for a large burden of cancers, heart disease, and respiratory disorders. Drug abuse among youth has become particularly alarming, with many students and unemployed young people falling into addiction due to peer pressure, curiosity, stress, and easy availability. Opioid abuse is a major concern in several states such as Punjab, Haryana, Rajasthan, Uttar Pradesh, and parts of the Northeast. Heroin, opium, pharmaceutical opioids, and injectable drugs are commonly misused. Synthetic drugs such as methamphetamine, MDMA, and party drugs are increasingly seen in urban nightlife and among affluent groups. Inhalants such as glue, whitener, petrol, and correction fluids are often abused by street children and economically weaker groups because they are cheap and easily accessible. This shows that substance abuse affects all social classes, though the pattern of use may differ. Drug trafficking in India is linked with organized crime networks operating across national and international borders. Smuggling occurs through land borders, sea routes, airports, and courier systems. States bordering Pakistan, Myanmar, Nepal, Bangladesh, and coastal areas are particularly vulnerable. Traffickers use modern communication methods, hidden transport systems, and money laundering techniques to avoid detection. The profits from illegal drug trade often finance criminal gangs, arms smuggling, terrorism, and
