What are some of the health effects from exposure to ozone? Ozone is very harmful to the lungs. Exposure to ozone can make breathing difficult, inflame the lungs and lining of the respiratory tract, lead to permanent lung damage, and make it harder for the body to fight respiratory diseases. Symptoms to watch for include coughing, shortness of breath, and chest tightness/chest pain.
Nicotine can cause many health problems. It can temporarily raise blood pressure and heart rate because it causes blood vessels to narrow. Nicotine can also make the blood more likely to clot and block an artery, and it can cause damage to the lungs and make breathing difficult. Nicotine in the body is first processed by the liver and then excreted by the kidneys. Over time nicotine can have negative effects on the kidneys.
