Sadly become passive smokers, although not smoke cigarettes, but they have to go get the sap.
In addition to risk of lung and respiratory disorders, auditory passive of smokers are threatened by others who smoke.
Some studies have indicated that smokers, whether they had stopped and was still smoking, at risk of hearing loss.

As a result, passive smokers have a worse hearing loss than those not exposed.
Hearing loss is mainly they can not catch the talks in a rather noisy environment.
Not only that, passive smokers are also threatened with having deaf based on examination of all frequencies of sound.
"We do not know the safe limits of cigarette smoke to avoid the risk of ear disorders.
However, the most secure is not exposed at all," said Dr.
