I have a problem with our government taxing legal activities in an effort to discourage them. Sin taxes just don't seem to fit in with the concept of a free nation. I don't like the idea of the politians in power at any given time determining what sins should be taxed. I imagine back in the fifties there were those who might want to tax rock"n"roll and maybe in the sixies long hair and peace symbols. There are polititians today objecting to low baggy pants and rap music. Some even advocate making some of these activities against the law.
It seems like every week there is some substance now determined to cause cancer. I have no problem with advocating people do not eat so much red meat or avoiding charcoal cooking for instance but that is different than trying to tax it out of existence.
