Since I have been seeing and knowing that the people in the entirely world absolute smoke from work, party, house, and everywhere. Do you know what can be dangerous for nonsmokers who actually has had a secondhand? It can be dangerous for them because they exhale the gas from the smoker who is smoking nearby them; that's how it can be dangerous by exhaling it. If it happens often to nonsmokers who had has a secondhand. it will lead them to death either healthy problems! If you disagreed with me then that's fine, you can find the information from your doctor, teacher, or the internet. xD
