Hi person from outer space.  Which planet are you from and what brought you to visit this planet?  To answer your question, smoking is the process of setting on fire and inhaling dried tobacco leaves that have been shredded and encased in very thin paper (which holds them together).  It is a pleasurable experience because it releases nicotine into the blood stream which makes us humans feel relaxed and happy.  Too much nicotine is poisonous though and can kill people.\n\nThe negative side of smoking is that traces of tar are left in the lungs and this can cause bad problems over time.  Also smoking has been linked to all sorts of cancers.  \n\nAt the moment it is considered very anti-social to smoke cigarettes, and a lot of people are coming under pressure to quit.\n\nAs an ex-smoker myself, I recommend stopping for fitness reasons.  I have found it much easier to do physical activity for extended periods of time since I stopped smoking.  However, I do miss smoking and one of the first things I would do if armageddon was due would be to smoke a pack of cigarettes.

Secondhand smoke contains twice as much tar and nicotine per unit volume as does smoke inhaled from a cigarette. It contains 3X as much cancer-causing benzpyrene, 5X as much carbon monoxide, and 50X as much ammonia. Secondhand smoke from pipes and cigars is equally as harmful, if not more so.\n\nSecond hand smoke is a toxic cocktail consisting of poisons and carcinogens. There are over 4000 chemical compounds in second hand smoke; 200 of which are known to be poisonous, and upwards of 60 have been identified as carcinogens.\n\nWhen a cigarette is smoked, about half of the smoke is inhaled / exhaled (mainstream smoke) by the smoker and the other half floats around in the air(sidestream smoke).\n\n No one should be forced to breathe in air tainted with cigarette smoke.

What we call flame is burning gas. So when you blow it, the gas is dispersed and the flame is "out" as it will not be burning anymore.

I hate it when people smoke next to me. Usually when I go somewhere where smoking is allowed, people stick the cig right in your face.  Hate that.

First off I just want to say that Second Hand Smoking is not linked to any kind of health risks. If anyone did a little research on the topic they would find out that the studies that the EPA did in the early 90s suggested no links. They fudged the numbers and the methods to make it look like there was a link.\n\nTrue smoking is linked to hazards, but so is drinking, eating too much, and just about every other thing that humans do in a daily life. Hell, driving is hazardous, do you think we should outlaw that as well? It is my god-given right to do whatever the hell I want with my body as long as I don't put others in danger, and if you look at the links below you will see second hand smoke is not proven to be dangerous.\n\nThey reason people want to outlaw smoking, is because everyone today is totally ignorant to the facts. They believe what they are told, and they are told that second hand smoking is dangerous. People today want to be politically correct all the time. Just because you don't like what I am doing doesn't give you the right to make me stop. Thats like telling someone to stop eating meat, because they are a veggitarian. What is this world coming to???\n\nOh by the way, I have never smoked a day in my life. I can't stand it, but I'm not going to take away somebody's rights just because I don't like it. I'll just enjoy myself somewhere else.

they're both bad second hand smoke is worse because most people who are inhaling the second hand smoke aren't ususally smokers, so it affects them more. I recently read a dear abby letter that addressed this question. http://news.yahoo.com/s/ucda/20060126/lf_ucda/dangerposedbysecondhandsmokeiscalledintoquestion;_ylt=AvRvjRtt.OVVBMI5k8l73bnNbbUC;_ylu=X3oDMTBjMHVqMTQ4BHNlYwN5bnN1YmNhdA--

I'm a smoker (no, not bragging or trying to justify it....stupid habit). Still, as a smoker, I'm really irritated by smokers who do that. I always use an inside ash tray, besides making sure I'm way downwind of non-smokers even when I smoke outdoors. I think it's just the decent thing to do. Also, throwing cigs out of a moving car window is dangerous, not to mention stupid!

If they are a smoker it is possible to not get all the smoke out when exhaling the cigarette drag. They can at a later time (not much later) force it out while apparently not smoking. I have seen someone do this before.

Well one thing second hand smokes does for me is it gives me migraines for hours and even days. I really don't think I should have to suffer when I do nothing in return. But smoke isn't the only thing that gives me really bad headaches other strong odors do too like perfume.

Stick your bottom lip out and let the smoke fall out while simultaneously sucking in the smoke with your nostrils. Make sure you do not inhale the smoke before you do it.

I'm a non-smoker, and I believe that I shouldn't have to be exposed to second-hand smoke that might harm me.  However, it's getting kind of ridiculous when it's being banned in bars.  Drunk people can be hazardous to the health of those around them too - shall we ban drinking in bars next?  I think reasonable people can agree that smoking in a bar is acceptable behavior.  There's nothing wrong with someone opening his own bar and saying "you can't smoke in my bar," but to make it an across-the-board law seems extreme and unnecessary.\n\nIt's also too extreme to ban smoking outdoors.  There have been no studies or data suggesting that being exposed to second-hand smoke in an outdoor, well-ventilated area is hazardous to one's health.  So I don't think smoking should be banned at bus stops, parks, etc., like some cities are doing.

Buildings in which many people smoke trap the fumes and anyone entering that atmosphere is subject to second hand smoke. Mostly in pubs, clubs, etc.

If you inhale the smoke it is unhealthy and can possibly give you lung cancer.\n"The American Heart Association estimates 40,000 die each year from heart and blood vessel disease caused by second-hand smoke".

The government will always controll us-there's no getting away from that.  I have been living in scotland for 3 months now, and have been working in a pub for the duration, and i've yet to make up my mind whether its a good thing or not.  As a non smoker, i can see the benifits of not stinking of smoke or inhaling second hand smoke all night.  However on the flip side, if i really hated stinking of ciggeretts and inhaling second hand smoke, i wouldn't work in a smokey enviroment, and i would stay away from similar enviroments.  What i DON'T think is a good thing is crowds of 20 to 30 people gathering outside a pub/club for a smoke-in the pouring rain. I think proper ventilation and/or a beer garden.  They are fantastic. especially with BBQs.
