>Smoking may be self medicating for depression and at least one study suggests smoking lowers the risk of death for people who suffer depression

That's interesting because nicotine contains MAOI(monoamine oxidase inhibitors) compounds that are used treat depression.

Nicotine itself is not MAO inhibiting, other compounds in tobacco have this effect (which may be synergistic/potentiating the nicotine effects)

Not may, it definitely does. There's a lot of research that shows the combination of harmala alkaloids and nicotine are a lot more addictive than either one alone.
