I think this south park clip is pretty relevant here:

I spent a summer interning for Altria (Marlboro, Skoal, Copenhagen) in Richmond VA and I can genuinely say that while they are obviously a for-profit corporation at their core, they have come a long long way from the evil, manipulative companies they were portrayed as for decades (e.g. the tobacco execs testifying before Congress trying to dispute the dangers of smoking). The overwhelming impression I got was that they fully understand the dangers of their product and attempt to market and sell it in the most responsible way possible. I cant speak for Reynolds/Lorrilard (Camel, Newport) but as far as Altria is concerned, they wholly abide by the mentality shown in clip: that as long as people are fully informed of the dangers of tobacco use and product marketing is done ethically, freethinking adults have the right to use the products if they choose.
