A lot of people says it helps with dream vividness and recall. A few people say the opposite and others say it doesn't have an effect on dreams at all.

I don't think there is any scientific research of the effects of tobacco and recall. I looked up the subject and found a few threads on it you should read:

-http://www.dreamviews.com/f44/tabacco-59137/index2.html
-http://www.dreamviews.com/f11/smokin...ave-lds-10590/
-http://www.dreamviews.com/f45/tobacco-38246/

After reading a lot of different opinions, I would have to say that is affects people in different ways. I guess it would just depend on how your body reacts to it. Hope this helped a bit!
