(a)must not contain any additive referred to in regulation 16 (no vitamins, colourings or prohibited additives in tobacco products);

(c)must not contain substances other than the ingredients notified under regulation 31, unless present in trace levels, where such trace levels are technically unavoidable during manufacture; and
