“20A Priority list of additives - enhanced reporting
1 A producer of cigarettes or hand rolling tobacco which contain an additive listed in Schedule 2 must—

(i) compiling the available scientific literature on the additive concerned; and
(ii) summarising the data, whether published or not, which is available to the producer on the effects of that additive; and
(c) such supplementary information regarding the additive as the European Commission or the Secretary of State may request.
3 The relevant deadline is—

20B Research study into additives
1 The study referred to in regulation 20A(1)(a) must be a comprehensive study which examines whether an additive—
(a) contributes to the toxicity or addictiveness of the product concerned, and whether this has the effect of increasing the toxicity or addictiveness of the product to a significant or measurable degree;
(b) results in a characterising flavour;
(c) facilitates inhalation or nicotine uptake;
(d) leads to the formation of substances that have CMR properties, and if so—
(i) in what quantities; and
(ii) whether this has the effect of increasing the CMR properties of the product concerned to a significant or measurable degree.
2 The study must also—
(a) take into account the intended use of the product concerned;
(b) examine in particular the emissions resulting from the combustion process involving the additive concerned; and
(c) examine the interaction of that additive with other ingredients contained in the product concerned.
3 Two or more producers who use the same additive in their products, in a comparable product composition, may carry out a joint study.”
