Question

Quizplus · Accepted Answer

Filtered cigarettes are designed to reduce the amount of smoke, tar, and fine particles inhaled during the combustion of a cigarette. However, they do not necessarily have a higher concentration of tobacco, nicotine, or carbon dioxide. The filtration process primarily affects the tar content, which can be higher in concentration in the smoke that passes through the filter, as some of the tar components are smaller and can pass through the filter more easily than larger particles. This does not mean the overall tar delivery to the smoker is higher, but the concentration in the smoke itself can be affected by the filtration process.
