The smoker.
Smoker: person who smokes cigars, cigarettes, ect. and may develop lung cancer. Smokers usually have bad breath, yellow teeth, a hard time breathing, lung problems, and other unhealthy symptoms. Nonsmoker: Person who doesn't smoke but may be a second hand smoker. A second hand smoker has been with a smoker almost all their life.
Sure, the smoker blows smoke into the face of the second-hand smoker who inhales and runs from the room and exhales the smoke into another person's face. That person would be the 3rd hand smoker. Not too likely.
Someone who breathes in second hand smoke is called a passive smoker.
While exposure to secondhand smoke is harmful and can increase the risk of heart disease, cancers, and lung conditions, it is unlikely to directly cause death. However, long-term exposure can contribute to serious health issues over time, particularly in individuals with preexisting conditions. It is essential to avoid secondhand smoke whenever possible to protect your health.
Second hand smoke... it is nasty >:(
yes its possible by second hand smoke
Depends on what you mean by "dirty" Second hand smoke causes the same risks as smoking yourself - cancer, loss of the sense of taste and smell, coughing, etc. You also stink just as much after you have been with a smoker as the smoker stinks.
Second-hand smoke can cause scaring of the lungs.
It isn't, its just usually 'second hand smoke' is being inhaled by a 'non-smoker' The active smoker receives the primary smoke and because he shares the environs where the primary smoke is created he inevitably receives the secondary smoke equally.
Of course! Second hand smoking! If you are around a smoker you can inhale the smoke that they have been smoking, and get lung cancer and tumors and a whole bunch of crappy stuff.
It means the ability to stop a mechanical watches second hand in order to synchronize it to the correct time .
