Karnataka has reported over 20,160 cases under the Narcotic Drugs and Psychotropic Substances Act, 1985 in the past four years, signalling a growing challenge for law enforcement agencies across the state.
While Bengaluru continues to lead in the number of cases, police officials are increasingly concerned about the emergence of new hotspots in cities like Mangaluru, Shivamogga, and Mysuru.
Bengaluru leads, but other cities catching up
Between 2023 and 2026, Bengaluru recorded 6,743 cases under the NDPS Act. Mangaluru followed with 2,665 cases, while Shivamogga reported 1,290 and Mysuru 722 cases.
Officials noted that every district and police commissionerate in Karnataka has reported drug-related cases during this period, indicating the widespread nature of the issue.
Multiple supply routes, no single syndicate
According to police sources, there is no single organised network controlling drug distribution in the state. Instead, substances are being trafficked through multiple routes, including entry points from Maharashtra, Rajasthan, Gujarat, and northeastern states, with links to international sources such as African countries.
Ganja cultivation on the rise
Apart from trafficking, Karnataka is also witnessing the cultivation and manufacture of banned substances. Ganja remains the most commonly grown drug, with police booking 165 growers and manufacturers since 2023.
In addition, authorities have registered cases against 5,366 dealers involved in the distribution of narcotics.
Synthetic drugs less prevalent
A senior officer associated with the Anti-Narcotics Task Force stated that while both natural and synthetic drugs are present, the consumption of synthetic substances remains comparatively lower.
Most synthetic drugs are reportedly brought into the state illegally, with occasional manufacturing cases detected in cities like Mysuru.
Educational hubs under watch
Authorities have flagged educational institutions as emerging centres for drug consumption and distribution. Increased monitoring in colleges and hostels has become a priority for enforcement agencies.
Sudheer Kumar Reddy, Commissioner of Mangaluru City Police, stated that the higher number of reported cases in the city reflects intensified policing rather than a spike in usage.
He added that over 150 drug dealers are currently in custody and that a dedicated helpline has been introduced to report drug-related activities in educational institutions.
Awareness and enforcement efforts
Data from the Home Department shows that between 2023 and 2025, police conducted 58,010 awareness workshops across educational institutions in Karnataka.
Authorities continue to stress a combined approach of enforcement and awareness to curb the spread of narcotics in the state.
A growing concern
The rising number of cases and the spread of drug activity beyond Bengaluru highlight the evolving nature of the challenge. Officials emphasise the need for sustained vigilance, community cooperation, and preventive education to tackle the issue effectively.
