    JACK A.M.; FISHER C.R.
    University of Kentucky, Lexington, KY, USA
    The FDA has issued an ANPRM to obtain information for developing a product standard that would lower nicotine to non-addictive levels, and requested comments on a limit of around 0.3-0.5 mg/g. We do not believe that this limit is technically feasible on a ...

    University of Kentucky, Lexington KY USA
    Production guidelines caution burley tobacco growers against using water sprays to bring tobacco into case and storing high-moisture tobacco because of concerns that these practices can lead to the accumulation of TSNAs. A series of experiments over three ...
