Cigarettes

[chainfire]

This question just dawned on me last night. When a person lights a cigarette, they then puff it on the opposite side. How does the person get any chemicals when the other side of the cigarette is lit?
I'm sorry if this question doesn't make any sense, i'll try to make it clearer if there are any problems

The chemicals are in the smoke that the person inhales. Sucking it through a tube (the cigarette) is the most efficient way to get the smoke into the mouth, it would be possible to smoke a cigarette by lighting one end and inhaling the loose smoke from that end, however some would get lost in the environment. Incindentally when the person is not sucking on the cigarette the smoke does not get inhaled and people nearby "passive smoke".

II, how can people 'passive smoke' without inhaling?

Chainfire, do you smoke? If you do what do you think those yellow stains on the butt of the cigarettes are when you're smoking?

The smoke that isn't inhaled by the person smoking the cigarette in question is released into the environment where others not (not the people actually smoking the cigatette in question), inhale the smoke, this is known as passive smoking. Sorry for not making this crystal clear for you first time.

II, people 'passive smoke' regardless of whether you inhale or not.

Justsia - If the smoker inhaled all the smoke form the cigarette, there would be none left for anyone else to passively smoke. I think that was the point Il was making.
ie any of the smoke not inhaled by the smoker is then available to everyone else to smoke for free.
