來了....
我一直覺得這個一點也不合理阿, 暴露在較小劑量的化學物質之下會產生更大的危害,請問來源是什麼, 有經過哪些的對照實驗, 還是只是來自禁菸的宣傳?

Despite reports to the contrary, secondhand smoke is not worse than active smoking. The toxicology of tobacco smoke is the same irrespective of the method of exposure. The factors of dose, concentration, duration, and host susceptibility all contribute to the adverse health effects observed in an individual. So-called secondhand smoke produces adverse health effects in individuals compared with those not exposed to any form of tobacco smoke. This finding forms part of the medical basis of legislation to limit unwanted potential exposures to tobacco smoke in public venues.
