After smoking a cigarette, the chemicals from the smoke are absorbed into the bloodstream through the lungs. While the effects of nicotine diminish relatively quickly (within hours), other harmful substances such as carbon monoxide and various carcinogens can linger in the bloodstream for longer periods. These substances can remain detectable in the blood for up to 10 days after smoking, depending on factors such as frequency of smoking, metabolism, and individual health conditions.
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."
Up to 3 days dear sir, although if you have a slow metabolism you might be in trouble :D

How long does it take Dilaudid to get into the blood stream.
Generally until you wash them.
It can be detected. The metabolite from nicotine will stay in your system up to 4 or 5 days.
Short answer: yes. Long answer, inhaling cigarette smoke is bad, inhaling diluted cigarette smoke is less bad -- but given ten years, not good.
Not long, maybe a week at most if there was no direct inhilation. Just a word of advice, if you want to smoke weed, then that is fine, its your choice as a free individual to do so, however you should not expose your children to it.

The smell of cigarette smoke can linger in the air for a long time. The smell can get into the carpet and the walls, and become a permanent scent in a home.
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!"
Contrary to what Tobacco Control would say, there is absolutely no evidence that smoking the occasional cigarette is harmful - as long as it is the only the occasional one!
