Where a drug of dependence is contained in a mixture weighing less than the column 2A quantity specified in Schedule Eleven, Part 3, the 'commercial quantity' is determined under sub-paragraph (ii) of s.70(1)(c) by reference to the column 2 quantity of the pure drug, not by reference to the weight of the mixture. Sub-paragraph (ii) is not confined to non-mixtures but operates as a residual provision applying whenever the conditions of sub-paragraph (i) are not both satisfied.
