    The textbook talks about how the nicotine and carbon monoxide in cigarettes attaches to haemoglobin in the blood, so if someone was smoking passively, would they get some of the nicotine, increasing THEIR risk too? Or is it just the actual smoker who has the risk?

    You get the CO - not sure bout the nicotine, though passive smoking does what it says on the tin, so I'd assume so.

    Well, not heart disease using the logic you have provided.

    You would have a hypoxia.

    However, maybe heart disease is a problem from second hand smoking in general.

    It would be impossible to say that second hand smoking directly causes heart disease without providing substantial amounts of evidence of breakthrough studies. There have been studies showing passive smoking increases the risk of heart disease, as do a lot of unhealthy lifestyle activities. So you can say second hand smoke increases the risk of heart disease, but you can't say it causes heart disease.
