The European Commission and its independent Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) have published their final Opinion on Additives used in tobacco products, identifying those that should be placed on the priority list foreseen in the Tobacco Products Directive.
The SCENIHR identified 48 single chemicals to be placed on the priority list. These compounds were selected because they have or are suspected to have one or more of the following properties:
• toxicity in unburned form (including carcinogenic, mutagenic or toxic for reproduction)
• facilitating inhalation or increasing nicotine uptake, which may contribute to addictiveness
• characterising flavour, one of the factors potentially contributing to attractiveness
• formation of any kind of toxic chemicals after combustion
The full list of additives and details about their selection can be found in the Opinion, on the website
