Cigarette smoke never enters the bloodstream, and so the question cannot be answered as asked. Cigarette smoke contains over 4,000 individual chemicals, many of which are gases which may cross the blood-gas barrier of the alveoli and enter the blood stream. Many of the particulates may similarly be trapped in the mucus of the trachea wherein other compounds may be leached from the particles and eventually enter into the blood-stream. The toxicological fate of each of these compounds is unique for that compound, and the elimination rate is therefore different for each. Various compounds may be sequestered in other tissues where, during times of biological stress, or other biological changes, be again released into the blood. Without knowing which specific compound is of interest, it is impossible to provide a general answer of "how long" the "average" compound may remain in the "blood stream."

During the Vietnam War, that was called a "smoke break." Long enough time to smoke a cigarette. Added to that command was, "...if you don't have one, borrow one from your buddy!"

Breathing in microwave smoke and cigarette smoke can both be harmful, but they differ in composition and health effects. Microwave smoke typically comes from burning food, which may release various harmful chemicals depending on the materials involved, while cigarette smoke contains a complex mix of toxic substances, including tar and nicotine. Both can irritate the respiratory system, but cigarette smoke has more established long-term health risks, including cancer and heart disease. It's essential to avoid inhaling any type of smoke for optimal respiratory health.
