You are quite correct, Jon - neither Toluene nor MEK are regarded as being carcinogenic (except in California, where apparently EVERYTHING is) . . .
Please stop these uninformed and foolish remarks. The issues with a number of solvents in California are about air pollution, not cancer per se. California's Proposition 65 does require "cancer danger" notices for a great many substances (all of which, incidentally, ARE proven carcinogens), but that's a different story.
