There's MAOIs in tobacco that are not present in gum or e-cigs. MAOIs change the psychoactive effects of nicotine. There is also some evidence that MAOIs significantly increase the addiction potential of nicotine. A little off topic, but I find that cigarettes really work for me as a software developer. Program for a couple hours, and then smoke a cigarette, rinse and repeat. More often than not, I catch bugs in my programs while smoking, not while at the computer. It significantly improves my cognition while also inducing a calm and reflective state. Part of this is probably from being alone and stepping away, but the tobacco definitely does have a strong effect separate of this.
