Big Tobacco didn't roll over and play dead when they lost the settlement to the State of Minnesota a couple of years ago. Thanks to a sympathetic Repubican majority in the House, the tobacco lobby was able to kill a bill before the Legislature this year that would have eventually required cigarettes to be self-extinquishing. It should be a simple matter to remove those chemicals.
Some brands have products that are self-extinquishing.
Merit has added little bumps to the paper to make the cigarette go out without changing the chemical composition of the tobacco. But Big Tobacco doesn't want to be pushed into anything. Representative Ozment, a Republican, Chair of the Environment and Natural Resources Policy Committee, and a firefighter in his life outside the Legislature, authored the legislation. It failed by one vote on strict party lines in the Commerce Committee. Ozment's Republicans voted against it.
