With the controversy over missing five crore tablets of the de-addiction drug, buprenorphine nalaxone, refusing to die down, Chief Minister Capt Amarinder Singh today constituted a three-member committee to probe the matter.

Over five crore tablets were found missing from the record entered into the online registry system by private centres

The government had served notices to 23 centres and one pharmaceutical company under the NDPS Act. But it is yet to find out whether these tablets were issued to addicts or sold illegally

Additional Chief Secretary Anurag Aggarwal had raised the issue after Health Minister Balbir Singh Sidhu ‘let off’ the de-addiction centres by issuing a warning Aggarwal wanted action against the centres under the NDPS Act.

The Narcotic Drugs and Psychotropic Substances Act, 1985, commonly referred to as the NDPS Act, is an Act of the Parliament of India that prohibits a person to produce/manufacture/cultivate, possess, sell, purchase, transport, store, and/or consume any narcotic drug or psychotropic substance.

Under one of the provisions of the act, the Narcotics Control Bureau was set up with effect from March 1986. The Act is designed to fulfill India's treaty obligations under the Single Convention on Narcotic Drugs, Convention on Psychotropic Substances, and United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
