2. Each Party shall ensure that for the period from 1 July 1991 to 31 December 1992 its calculated levels of consumption and production of the controlled substances in Group I of Annex A do not exceed 150 per cent of its calculated levels of production and consumption of those substances in 1986; with effect from 1 January 1993, the twelvemonth control period for these controlled substances shall run from 1 January to 31 December each year.

3. Each Party shall ensure that for the twelvemonth period commencing on 1 January 2000, and in each twelvemonth period thereafter, its calculated level of consumption of the controlled substances in Group II of Annex A does not exceed zero.
