On 29 June 2011, the Bolivian government denounced the 1961 Single Convention on Narcotic Drugs as amended by the 1972 Protocol, indicating its intention to re-accede with a reservation allowing for the traditional use of the coca leaf. This decision was triggered by Bolivia’s need to balance its obligations under the international drug control system with its constitutional and other international legal commitments. The move follows the rejection of Bolivia’s proposal to amend the Single Convention by deleting the obligation to abolish coca leaf chewing (Article 49) earlier this year.
The International Narcotics Control Board (INCB) regrets the decision by the Government of the Plurinational State of Bolivia to denounce the Single Convention on Narcotic Drugs, 1961, as amended by the 1972 Protocol. On 29 June 2011, in an unprecedented step, the Government of Bolivia denounced the Single Convention on Narcotic Drugs, 1961, as amended by the 1972 Protocol, to which the State of Bolivia had previously acceded. The Government also announced its intention to re-accede to this Convention but with a reservation regarding specific treaty provisions.
