I don't think nicotine really helps, But you know what I could be wrong maybe somehow this may effect others differently for instance I'm a Natural but I've realized that my Lucid Phase are heightened right around this time when there is a full moon. At least that's how it effects me. But I used to smoke and I lucidity was never intensified. But like I mentioned different strokes for Different folks something that may work for you may not necessarily work for me and vice versa. See to me that's the beauty of Lucid Dreaming. Everyone has a different induction method.
