BUSINESS MEMO: MASSACHUSETTS TO REQUIRE LISTING OF TOBACCO INGREDIENTS

Massachusetts is about to become the first state to require the tobacco industry to divulge the exact ingredients -- from chocolate to ammonia -- in each brand of cigarettes, cigars and chewing tobacco.

Tobacco lobbyists complain the law is illegal, forcing them to reveal trade secrets to competitors. Besides, they say the industry has already handed over a list of 599 ingredients found in cigarettes.

But anti-smoking activists say the list does not give the exact amounts in each brand -- critical to determining whether some cigarettes are more harmful than others.

And they say letting people know exactly what they are inhaling or chewing, would be a powerful way to get them to stop.
