In the case of those with schizophrenia the long term health effects could be seen as being offset by the benefits ( a partial or complete cessation of symptoms for some time after each cigarette ).
But those without schizophrenia have no such justification.
And there are ways of helping gut motility without the risks associated with smoking.
I've read of similar applications of tobacco for people who are suffering with Parkinson's, and I've met such people who self-medicate in this way and feel they get some benefit from it, but I don't know if there's any scholarship on this.
A friend of mine has been researching the dopamine cycle in humans, which has to do with experiences of pleasure and euphoria (and hence behaviors such as thrill-seeking, risk-taking, sex-having, and drug-using). His comments were interesting to me: one cigarette gives about ten times the dopamine response as does one orgasm. So, brain-chemically, one could masturbate to orgasm ten times successively in a short interval of time (?!), or smoke a cigarette, to get the same kind of lift. Which is more efficient? The answer: a dose of methamphetamine, impacts the dopamine thing more intensively than smoking or sexing by degrees of magnitude. Again, I've not studied the science on this, but it seems credible and plausible enough for consideration here.
