Concept:
The
Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985 is the primary legislation in India that regulates the control and prohibition of narcotic drugs and psychotropic substances. The Act aims to prevent drug abuse and illegal trafficking of narcotic substances.
Under the NDPS Act, different schedules classify drugs and substances based on their legal status and regulation.
- Certain substances are strictly prohibited for manufacture, possession, sale, and use.
- Others may be allowed under strict medical or scientific regulations.
Step 1: Understanding the purpose of schedules in the NDPS Act.
Schedules under the NDPS Act list specific narcotic drugs and psychotropic substances and define the level of restriction or prohibition applied to them.
Step 2: Identifying the schedule containing prohibited substances.
Schedule I of the NDPS Act lists substances that are
completely prohibited except for scientific or very limited authorized purposes. These substances are considered highly dangerous and have strict legal restrictions.
Thus, the correct answer is:
\[
\boxed{\text{Schedule I}}
