In a major crackdown on drug trafficking, the customs department at Chhatrapati Shivaji Maharaj International (CSMI) Airport, Mumbai, seized approximately 8.6 kilograms of high-grade hydroponic weed, also known as hydroponic marijuana, valued at Rs 8.6 crore in the illicit market. The operation, carried out on June 2 and 3, led to the arrest of three Indian nationals who had arrived from Bangkok. The action was taken by officers of Mumbai Customs Zone III who were working on specific intelligence inputs regarding drug smuggling through air routes. Two passengers landed on June 3 by Thai flight SL218, while the third arrived earlier by flight VZ760, all from Bangkok. Acting on suspicion, customs officials intercepted the individuals shortly after they landed at the airport. Upon preliminary questioning, all three passengers displayed signs of nervousness and discomfort, raising red flags for the team. A thorough examination of their baggage led to the discovery of carefully concealed hydroponic weed—an advanced form of cannabis grown in controlled environments using nutrient-rich water instead of soil. This type of marijuana is known for its potency and high street value. The entire consignment, weighing 8.6 kg in total, has been seized under the provisions of the Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985. All three individuals have been arrested and further investigation is currently underway to determine the broader network behind this smuggling attempt. The seizure underscores the growing trend of synthetic and high-potency drug smuggling through air routes, especially from Southeast Asian hubs like Bangkok. The successful operation not only prevented a large quantity of narcotics from reaching the streets but also highlights the increasing use of airports like Mumbai for smuggling hydroponic marijuana. As international drug syndicates adapt with newer smuggling techniques, Indian enforcement agencies are stepping up efforts with sharper intelligence and advanced surveillance tools.
