Moreover, only 1 of 16 countries in the region submitted form D (annual information on substances frequently used in the illicit manufacture of narcotic drugs and psychotropic substances) for 2014 to the Board by the annual reporting deadline of 30 June, thus affecting the Board’s ability to analyse regional precursor trends and patterns. A comprehensive review of the situation with respect to the control of precursors and chemicals frequently used in the illicit manufacture of narcotic drugs and psychotropic substances in the region can be found in the report of the Board for 2015 on the implementation of article 12 of the 1988 Convention.
