The only thing I would try to force out of the Tabaco companies is that they have a free quiting program people can join. Afterall some people can't quit due to weak will power.. or lack of money for the aids that supposedly help.
Therefore they help people.. and many people would still smoke.. heck my mom I know doesn't want to quit.. so it would really only affect those who really really want to quit but for whatever reason have been unable to do so.
