Yes, I think we will see a mild increase. I even know some people who started smoking once it was legalized in their state (they were very cautious about run-ins with the law because of family history). I've been smoking since I was 17 and smoke pretty much every day still. However I think what is more important is that it's becoming more accepted and legitimized so that there can be worthwhile and meaningful studies done about the drug and the habits of its users, including driving accident statistics.
