D used in the United States does not result in any level of tetrachlorodioxin contamination. Other members of the phe-noxys in wide use are 2-(2,4-dichlorophenoxy)propionic acid (Dichlorprop or 2,4-DP), 4-(4-chloro-2-methylphenoxy) butanoic acid (MCPB), and 2-(4-chloro-2-methylphenoxy) propanoic acid (Mecoprop or MCPP) (18B18). None of these compounds [2,4-DB, 2,4-DP, MCPB, MCPA, MCPP, 2-(2,4,5-trichlorophenoxy)propionic acid] has been found in tobacco or tobacco smoke.
