Governor Dayton has broken with his Health Department commissioner over the extent of regulation needed on electronic cigarettes. Dayton says that he is uncomfortable with legislative efforts to put e-cigarettes in the same category as conventional cigarettes when it comes to prohibition of use in public spaces. His comments directly contradict testimony from Health Commissioner Ed Ehlinger. Dayton says he would sign a bill to restrict children’s ability to buy e-cigarettes, but he would likely oppose proposed restrictions on their use indoors. Ehlinger has described the vapor-emitting devices as “a threat to the health of the public” that could undermine the state’s law barring tobacco use in public buildings and most businesses.
