They were the first to identify the harmful affects of smoking. They were absolutely nuts but they were very intelligent.

Yes, chemicals can be detected in blood and other tissues from  tobacco use.  How long it can be detected depends greatly on what testing methode is used, how much and how often you chew and how determined the insurance carrier is in finding out.  The length of time is so variable because of these factors that it could be anywhere from weeks to months andeven longer in a forensic investigaton.

Have you considered hypnosis?    A good hypnotist can usually determine why he smokes, what he could do instead to satisfy the craving or addiction, and find the underlying causative factors that led him to begin smoking in the first place, and then use guided imagery and positive health suggestion to help the smoker decide to take a healthier path

There's really no way to tell unless he goes to a doctor. Some people can start smoking at age 10 and live to be 100...it all depends on your body.

1) Look at pictures of black, damaged lungs from a corpse's autopsy.\n2) Visit a hospice where people have suffered the effects of chemotherapy and are terminally ill and dying from lung cancer.\n3) Take a look at what a pack of cigarettes cost today and multiply the cost times the number of packs you smoke daily.  Then figure out how much you spend annually.

Hmm.  Well, in Safety Education a million years ago, I learned cigarette *smoke* contains hydrogen cyanide, among other yummy things.

No record of who actually discovered it. It is several thousands of years old. It can be naturally extracted from Willow bark.

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.

As early as in 1761, Dr. John Hill, a London physician, had recorded an early observation linking tobacco (specifically, snuff) and cancer. \nIn his analysis, “Cautions Against the Immoderate Use of Snuff,” he said that he discovered lumps on the lungs of frequent snuff takers. \nHope this helps

Smoking produces major changes in the flow of “feel good” chemicals between brain cells, both temporarily and long-term. And those changes in flow match up with changes in how smokers say they feel before and after smoking.\n\nIt's the first time smoking has been shown by positron emission tomography (PET) imaging to affect the human brain's natural system of chemicals called endogenous opioids, which are known to play a role in quelling painful sensations, heightening positive emotions, and creating a sense of reward. It's the same system that is stimulated by heroin and morphine.\n\nAs for drinking...'As for the effects in general, it's the early stages that feel good, of course. Usually, I hate actually being pissed; but the initial feeling of altering my state of mind, of shifting the perspective a little, is very pleasant – I have a sense of stress evaporating, of neuroses fading into the background for a while
