          - [Docket No. FDA-2012-N-0212]

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Notice of public workshop; request for comments.

The Food and Drug Administration (FDA), Center for Tobacco Products is announcing a scientific workshop to solicit feedback on analysis of tobacco products. The analyses of tobacco products often involve tobacco reference products, which are used primarily as controls to ensure that the results of the analyses are reliable and accurate. This scientific workshop will focus on understanding how tobacco reference products are used and the testing methods used to analyze tobacco products. FDA will invite speakers to address scientific and technical matters relating to the testing of tobacco reference products and the analytical methods used to measure constituent levels in tobacco products and smoke. FDA is also opening a public docket to receive comments on these topics.

# SUPPLEMENTARY INFORMATION:

## I. Background and Workshop Topics

The purpose of this scientific workshop is to obtain information and comments from appropriate scientific experts on analysis of tobacco products. Such experts could include, but are not limited to, scientists from academia, tobacco product manufacturers, and contract testing laboratories. The workshop will include scientific experts who will present scientific and technical information on testing of tobacco reference products for different types of tobacco products. The types of tobacco reference products to be discussed include, but are not limited to, smoked tobacco products, smokeless tobacco products, and other tobacco products not classified as either smoked or smokeless products. FDA would like to discuss how the tobacco reference products are used for testing purposes to ensure accuracy of analysis of tobacco products. Tobacco reference products are analyzed alongside test tobacco products (i.e., during every step of the analysis). Tobacco reference products are intended for use during analysis of tobacco products and are not intended for human consumption. Tobacco reference products are finished tobacco products and are distinct from internal reference standards, which are chemicals or mixtures of chemicals. Internal reference standards are used during only certain steps of the analysis of test tobacco products (e.g., when running samples).

The scientific workshop will include discussion of analytical methods for measuring certain constituents in tobacco products and smoke. The aspects of analytical methods that will be discussed include extraction, separation, and detection methods. For example, FDA would like to get input from scientific experts on how tobacco-specific nitrosamines (TSNAs) are extracted from smokeless tobacco products and cigarette smoke particulate matter and what instrumentation (e.g., gas chromatography-mass spectrometry) is used to measure the levels of TSNAs.

                    FDA is interested in receiving substantive scientific input at the workshop and in the docket. The input from the scientific workshop may assist us in developing future scientific                           ( print page 14815)                        workshops regarding analysis of tobacco products.                

## II. Workshop Topics for Discussion

FDA will explore all or some of the following topics during this scientific workshop:

#### 1. Availability, Manufacture, and Characterization of Tobacco Reference Products

A. Discuss the current availability of tobacco reference products for different types of tobacco products and what new products would be beneficial.

B. Discuss the types and blends of tobacco used in reference products. What additional blends or other product characteristics should be most applicable for all products, both those currently and those expected to be introduced on the market?

C. Describe the storage conditions for tobacco reference products to ensure shelf life. Please provide data that shows product changes under different storage conditions. What storage conditions are most critical in maintaining product integrity? What precautions should be taken to ensure product integrity?

D. Discuss the stability of the tobacco reference products and methods used to verify product stability. What precautions are taken to maximize product stability? What product characteristics are most stable and which are least stable?

E. Describe any ongoing work to develop tobacco reference products that are not currently available for laboratory use. Discuss considerations made when determining the need and developing a new tobacco reference product.

#### 2. Uses of Reference Products During Analysis of Tobacco Products

A. Discuss the physical and chemical measurements performed on tobacco reference products during analysis of tobacco products. Please provide data. How are reference products used in research and manufacturing?

B. Discuss the advantages and disadvantages of using one or multiple tobacco reference products when performing analysis of a given tobacco product type.

C. Discuss the procedures used when transitioning from using one tobacco reference product to using another tobacco reference product for the same tobacco product type to ensure long-term consistency in findings.

D. Discuss the policies, procedures, and frequency related to discarding data for reference products due to unacceptable analytical results.

E. Discuss the policies and procedures used in research and manufacturing when no tobacco reference product is available for a specific type of tobacco product. Is there a policy of using a similar product when the specific reference product is not available? What considerations are applied?

F. Describe characteristics of a tobacco reference product that would provide advantages or disadvantages over another.

#### 3. Variability Observed in Measurements of Tobacco Reference Products

A. Provide data that address the variability that exists in the chemical measures of a reference product analyzed within the same laboratory. Describe how measures compare between different laboratories.

B. Provide data that address the variability that exists in the physical measures of a reference product analyzed within the same laboratory. Describe how measures compare between different laboratories.
