The North Carolina State University Tobacco Analytical Services Laboratory (TASL) serves as the central repository for a growing series of Smokeless Tobacco Reference Products (STRP’s). Early reference products produced in this program included the STRP1S1 and STRP2S1 (loose leaf chewing tobacco), STRP1S2 (dry snuff), STRP1S3 and STRP2S3 (moist snuff) products. These products are no longer available. The Product Tabs on the left are provided for information only.

More recently, the TASL has been working with members of the CORESTA Smokeless Tobacco Subgroup to provide a new series of standardized smokeless tobacco reference materials for use in scientific studies ( manufacture date - 2009). These have been designated as CORESTA Reference Products - CRPs. These products include CRP1 (Snus), CRP2 (Moist Snuff), CRP3 (Dry Snuff), and CRP4 (Loose- leaf Chewing Tobacco). See the links to the left of this page for basic information on these products. Due to a high demand for several of the CRPs a second batch has been produced (manufacture date -2016). These new CRPs are classified as CRP1.1 (Snus), CRP2.1 (Moist snuff),CRP3.1 (Dry Snuff) and CRP4.1 (Loose- leaf Chewing Tobacco).
