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.

DATES: Dates and Time: The public workshop will be held on April 11, 
2012, from 8:30 a.m. to 5:30 p.m., and on April 12, 2012, from 8:30 
a.m. to 4 p.m. Individuals who wish to attend the public workshop must

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

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?
