Cigarette

I just can’t understand why smokers find it so hard to quit smoking when it is notoriously known as unhealthy habit. And why so many youth fall victim by this vice.

Smoking seems to favor the creation of enzymes which facilitates the manufacturing of signalling molecules, like dopamine, into a part of the brain that processes information related to motivation and reward – so really smoking produces neuronal adaptations, similar to those caused by harder drugs, that make it hard for the smoker to quit (the addiction).

Add to it the social (engineering) pressures to stop smoking, which can lead some people to try smoking by curiosity or to continue in defiance in spite of the health risks, and it only makes it more difficult to quit for many smokers.

I’m trying to find out if and/or how cigarette smoke can cling to a person if no one is smoking in your presence (i.e. someone smokes in a room, you enter 2 hours later, you smell like smoke).

I need scientific facts so links to reports or studies would be greatly appreciated. Other possible questions I’d need answered for this report include:

Is it possible that smoke molecules can cling to you if someone smokes several rooms over?

Can the odor from an ashtray cling to a person (unlit cigarettes of course)?

If you’re around a person who smells like smoke, is it scientifically possible for the odor to rub off on you?

Thanks in advance for your help.
Is it possible the smoke smell is something a non-smoker would pick up after walking in the house? The odor may not necessarily be on the clothes but something "in the nose" of the person who smelled the smoke. Any scientific data to back it up?

Thanks
The reports on smoke molecules and how they "cling" to individuals. I have some data on how it sticks to an individual while in the presence of the odor but I need data on the lingering of the molecules/odor.

You can smell like cigarette smoke if you, your clothes, or the furniture you are sitting upon has been exposed to people that smoke.

If someone uses perfume or cologne and rubs up against you, some of that scent will linger on you. It’s gotten many a man in trouble. Also, I’m sure there are people out there who can tell you they work with people who they can smell coming way before they see them. It’s the same with cigarette smoke.

Ask a smoker what happens to the clothes they haven’t worn in awhile in their closet. They turn yellow wherever they’ve been exposed to the air.

I know from personal experience when I was a smoker that even before opening the door on my house I could smell the cigarette smoke lingering around the outside of the house. After I no longer smoked, I could smell that the house and car actually reeked of cigarette smoke.

If you are doing a report on whether or not smoking should be allowed in enclosed public places, I don’t think it should be. I respect your right to smoke, (I used to get irate at people who took the position I now take), but your right to smoke ends when I have to re-breathe the air you are polluting.
