I find the effects of second hand smoke on people easy to argue for. So, since Vlad was the only one who suggested I debate (and debate against it) I will.
--------------------------------------------------------------------------
I have a strong background in smoking (knowings its effects, what it can do, how it kills, etc). I have done countless research on this topic and lost many loved ones to cigarettes.
--------------------------------------------------------------------------
First lets start with second hand smoke. Since I don't want this post to get too lengthy (more than it already will), this is all I will focus on.
There are two kinds of second hand smoke that are produced at the same time. One is called mainstream smoke, which is what is exhaled by the smoker. The second kind is called 'sidestream smoke'. Sidestream smoke is what comes off the burning end of a cigarette.
Second hand smoke contains a mixture of more than 4,000 chemicals, and 50 of those are known cancer-causing products. It is a known carcinogen (cancer causing), and causes an increased risk for lung cancer on coronary heart disease. It is simply said as an 'increased risk' because no one can factually say cigarettes or second hand smoke cause it. (Think of it this way, some people never get lung cancer or die of it and live well into their prime.)
Children exposed to this have all KINDS of increases in sicknesses ranging from but not limited to, SIDS, asthma (which my sister now has since she was raised in a smoking environment), pneumonia, etc.
--------------------------------------------------------------------------
I've checked several sources and all agree the average for deaths among non smokers due to second hand smoke exposure estimates to be
3,000 deaths of lung cancer per year
35,000 deaths of coronary heart disease.
Other interesting statistics (due to second hand smoke):
An estimated...
8,000 to 26,000 new asthma cases come about in children
150,000 to 300,000 cases of bronchitis and pneumonia (age less than 18 months, and an average of 10,000 will require hospitilization).

Want to know how they find research that says your second hand smoke is in someone elses blood? Here it is as directly quoted from the national center for chronic disease prevention and health promotion:
Cotinine is a major metabolite of nicotine. Exposure to nicotine can be measured by analyzing the cotinine levels in the blood, saliva, or urine. Since nicotine is highly specific for tobacco smoke, serum cotinine levels track exposure to tobacco smoke and its toxic constituents.
In 1991, data showed that nearly 90 percent of the U.S. population had measurable levels of serum cotinine in their blood. The Centers for Disease Control and Prevention's National Report on Human Exposure to Environmental Chemicals found more than a 75 percent decrease in median cotinine (metabolized nicotine) levels for nonsmokers in the United States since 1991.
Children and teenagers, 3-19 years old, had higher levels of cotinine than did adults, 20 years old and above.

Here is a list of some chemicals in cigarettes that you may be familiar with:
1. Carbon Monoxide: Just stick your mouth on a car exhaust pipe, you get the same poison.
2. Tolune: It's an industrial solvent used in explosives
3. Formaldehyde: Remember those dead animals you had to dissect in high school and that smelly stuff they were preserved in so they don't rot? Yeah that's in there.
4. Hydrogen Cyanide: Your basic rat poison
5. Ammonia: Poisonous gas and cleaning chemical.
6. Phenol: This disinfects toilets.
7. Quinoline: It preserves specimens.
8.: Zinc: An anticorrosion coating for metals
9. Polonium-210: A radioactive element which is a known carcinogen (it causes cancer!)
10. Butane: Cigarette lighter fluid (because lighting the poison stick isn't enough)
11. Cadmium: Used in rechargeable batteries.
12. Acetone: This is in your basic nail polish remover
13. Naphthalene: Put in mothballs
Need I go on or would you like me to list more poisons that I don't want to breath in second hand?
Most ingredients put into a cigarette help foster a nicotine addiction.

I'm ending it here, I believe this is sufficient enough until someone debates back.
