What sickness can you get from breathing too much smoke from a fire?

Well for one, you can suffocate because of breathing in the smoke instead of oxygen. Lungs can also be damaged in much the same way of breathing in a smoker's second hand smoke. The alveoli can be destroyed, and the mucus membranes of your throat can become irritated. This could cause coughing and wheezing and lungs problems. Smoke can also trigger asthma is some cases.
