There simply isn't enough concentration of any hazardous substance in even the most smoke filled dive to do any damage.

Not even anywhere REMOTELY close to the truth.

Secondhand smoke can be harmful in many ways. In the United States alone, each year it is responsible for:

• An estimated 35,000 to 40,000 deaths from heart disease in people who are not current smokers
• About 3,000 lung cancer deaths in nonsmoking adults
• Other respiratory problems in nonsmokers, including coughing, phlegm, chest discomfort, and reduced lung function
• 150,000 to 300,000 lower respiratory tract infections (such as pneumonia and bronchitis) in children younger than 18 months of age, which result in 7,500 to 15,000 hospitalizations
• Increases in the number and severity of asthma attacks in about 200,000 to 1 million asthmatic children.

People who do not smoke, and who are exposed to the toxic chemicals in second-hand smoke on a regular basis, can suffer serious and life-threatening health problems.

In the long term, people exposed to second-hand smoke have a greater risk of suffering from lung cancer, nasal sinus cancer, heart disease, stroke, and breathing problems, including increased coughing, wheezing, pneumonia, bronchitis, and asthma.

People who live with someone who smokes and are exposed to tobacco smoke on a regular basis have a 30 per cent increased risk of developing lung cancer and heart disease.

People who do not smoke will suffer from the effects of breathing second-hand smoke right away. Even as little as 8 to 20 minutes can cause physical reactions linked to heart disease and stroke, such as increased heart rate, less oxygen to the heart, and constricted blood vessels that increases blood pressure and makes the heart work harder.

Pregnant women exposed to second-hand smoke can have a greater risk of miscarriages and babies with low birth weight.

I've got LOTS more where that came from.
