There are sibling comments discussing MAOIs, and I've heard about them before in relation to smoking. It makes me wonder if MAOIs alone would be better for smoking cessation. I don't think I'm all that addicted to the nicotine itself. There are plenty of other supposedly-addictive stimulants that I can take or leave at will and with no feelings of withdrawal, and nicotine does nothing to alleviate cigarette withdrawal for me, so I'm not sure it's even a necessary component. There are some NIH studies about MAOIs and smoking, but I'm not going to link them because I find them incomprehensibly dense.
