Necessity of establishing specific material showing Ganja dealing as a public health hazard

To justify the detention of a drug offender under preventive detention laws, the detaining authority must bring on record concrete material demonstrating that the specific narcotics dealings posed a widespread danger to public health. Merely registering criminal cases for possession or peddling of "Ganja" under the NDPS Act does not automatically satisfy the legal threshold of affecting public order. The order of detention must explicitly outline how the detenu's activities went beyond individual criminal liability to affect the general public or create widespread danger. In the absence of scientific reports, impact assessments, or factual material showing a grave threat to community health, generic assertions remain legally insufficient. The detaining authority cannot rely on broad generalized statements regarding the ill-effects of drugs on youth without connecting those effects to the detenu's specific actions. Judicial precedent mandates that missing link material regarding the actual public health impact invalidates the subjective satisfaction of the detaining authority. Therefore, specific and tangible proof linking the drug offence to public health disruption is indispensable. (Roshini Devi v. The State of Telangana and Others | 2026 INSC 41)
