Once demonization has eradicated tobacco from the public's grasp, these benefits may be sold back in pill form for an even greater margin of profit. Yay Capitalism!
I would chalk this this one up as a case of capitalism working [for the general good [this clarification shouldn't be necessary but it always is]].
Well, once tobacco has been socially stigmatized and huge taxes placed on it, anyway. I'm not sure nicotine gum/patches/e-cigs existed before the War on Smoking. I expect you could buy purified nicotine oil from chemical suppliers, but it'd be up to you to figure out how to use it (and do so without killing yourself).
I think we're seeing some of this now, with the greater attention being paid to e-cig products.
