Different substances are regulated differently because they have different risks for the population. Nicotine is significantly more addictive and harmful than marijuana which is why it is regulated differently than marijuana: https://en.wikipedia.org/wiki/File:Drug_danger_and_dependenc...
Need a citation here. I've read the literature and the current consensus (as far as I'm aware) is "we don't know what the harms are". There is a study which suggest that nicotine may increase cancer risk in mice, though it is not a direct cause and even then the study was inconclusive.
Your link is a chart which shows relative lethal doses of substances. Nicotine requires a "very high" dose, not one you would ever get in practice. Not sure what point you were trying to make with that.
