I smoke (trying to quit) and I don't think cigarette manufacturers are doing anything immoral. I enjoy smoking! Why else would I have ever tried it when I knew all the risks?
Nobody is getting tricked, here. People are selling a product that other people want.
Have you read "the easy way to stop smoking"? He makes a great point about the claim that smokers don't actually enjoy it. It's addiction, thinking you enjoy it is a mechanism of avoiding the guilt of the addiction. Or something like that, his argument was much more convincing.
