Is there a benificial effect from nicotinic acid from smoking tobacco?

Sorry, it wouldn't let me discuss this so I'll have to answer it. The answer is "yes."

Whether the answer is actually posted would be more of a political question. Perhaps the question should be, "is the nicotinic acid that we get from tobacco actually good for us?" Of course this brings up more questions such as 1) in what quantity? 2) when? (studies have shown that smokers are less likely to suffer burn out. Sorry I don't remember where I read the study.
