> The implication seemed to be that there were other things beyond MAOIs in tobacco that were (or helped nicotine to be) addictive; is that not the case?

Well, I don't know that it's not the case. There's a lot of stuff in tobacco, it wouldn't surprise me if there were other chemicals besides MAOIs with relevant psychoactive effects. But from the snippet you quote, I see why you might be reading that as a stronger claim than I intended. I'll amend that to '& possibly other compounds' so it's clearer.
