Tobacco is a plant that can be smoked in cigarettes, pipes, or cigars.
It's the same plant that's found in smokeless tobacco, known as dip, chew,
snuff, spit, or chewing tobacco. Smokeless tobacco is not lit and inhaled
like cigarettes, pipes, and cigars. Instead, smokeless tobacco is placed
between the lip and gum and is sucked on inside the mouth.
Tobacco contains nicotine, a chemical that produces a tingly or pleasurable
feeling but only for a short time. Also, nicotine is addictive. This means
that if you start to use nicotine, your body and mind will become so used
to it that you'll need to have it. Anyone who starts smoking is at high
risk of becoming addicted to nicotine. In fact, nicotine is said to be
even more addictive than heroin or cocaine.
Nicotine is a poisonous drug! Dozens of poisonous chemicals in tobacco
cause lots of diseases and illnesses, like heart problems and some kinds
of cancer. Some of these diseases take years to happen, but others can
affect you right away. For example, kids who smoke are much more likely
to get infections such as colds and pneumonia.
Nicotine is addictive. Most smokers use tobacco regularly because they
are addicted to nicotine. Addiction is characterized by compulsive drug-seeking
and use, even in the face of negative health consequences, and tobacco
use certainly fits the description.
Nicotine can act as both a stimulant and a sedative. Most cigarettes in
the market today
contain 2-10 milligrams (mg) or more of nicotine. Through inhaling smoke,
smoker takes in 1 to 2 mg nicotine per cigarette. There have been
in the sale and consumption of smokeless tobacco products also, and more
Nicotine is one of more than 4,000 chemicals found in the smoke from
tobacco products such as cigarettes, cigars, and pipes, is the primary
component in tobacco that acts on the brain. Smokeless tobacco products
such as snuff and chewing tobacco also contain many toxins as well as
high levels of nicotine. Nicotine, recognized as one of the most frequently
used addictive drugs, is a naturally occurring colourless liquid that
turns brown when burned and acquires the smell of tobacco when exposed

How Nicotine acts
Nicotine can act as both a stimulant and a sedative. Immediately
after exposure to nicotine, there is a "kick" caused in part
by the drug's stimulation of the adrenal glands and resulting discharge
of epinephrine (adrenaline). The rush of adrenaline stimulates the body
and causes a sudden release of glucose as well as an increase in blood
pressure, respiration, and heart rate. Nicotine also suppresses insulin
output from the pancreas, which means that smokers are always slightly
hyperglycaemic (high blood sugar). In addition, nicotine indirectly causes
a release of dopamine in the brain regions that control pleasure and motivation.
This reaction is similar to that seen with other drugs of abuse-such as
cocaine and heroin- and it is thought to underlie the pleasurable sensations
experienced by many smokers. In contrast, nicotine can also exert a sedative
effect, depending on the level of the smoker's nervous system arousal
and the dose of nicotine taken.
Most cigarettes in the market today contain 2-10 milligrams (mg) or more
of nicotine. Through inhaling smoke, the average smoker takes in 1 to
2 mg nicotine per cigarette. There have been substantial increases in
the sale and consumption of smokeless tobacco products also, and more
recently, in cigar sales.
Risks and consequences from long term smoking
Nicotine is absorbed through the skin and mucosal lining of the mouth
and nose or by inhalation in the lungs. Depending on how tobacco is taken,
nicotine can reach peak levels in the bloodstream and brain rapidly. Cigarette
smoking, for example, results in rapid distribution of nicotine throughout
the body, reaching the brain within 10 seconds of inhalation. Cigar and
pipe smokers, on the other hand, typically do not inhale the smoke, so
nicotine is absorbed more slowly through the mucosal membranes of their
mouths. Nicotine from smokeless tobacco also is absorbed through the mucosal
The medical consequences of nicotine exposure result from effects of
both the nicotine itself and how it is taken. The most deleterious effects
of nicotine addiction are the result of tobacco use, which accounts for
one-third of all cancers. Foremost among the cancers caused by tobacco
is lung cancer-the number one cancer killer of both men and women. Cigarette
smoking has been linked to about 90 percent of all lung cancer cases.
Smokers have an increased risk of developing:
such as pneumonia and chronic bronchitis;
emphysema (a progressive
and potentially fatal lung disease);
heart attack and coronary
cancer of the lung,
throat, mouth, oesophagus, bladder, kidney, pancreas, cervix, stomach;
disease due to decreased blood flow to the legs.
Overall rates of death
from cancer are twice as high among smokers than non smokers.
A chronic smoker who is dependent on cigarettes may find that they experience
withdrawal symptoms when they cut down or stop smoking cigarettes. These

In addition to lung cancer, smoking also causes lung diseases such as
chronic bronchitis and emphysema, and it has been found to exacerbate
asthma symptoms in adults and children. Smoking is also associated with
cancers of the mouth, pharynx, larynx, oesophagus, stomach, pancreas,
cervix, kidney, ureter, and bladder. The overall rates of death from cancer
are twice as high among smokers as among nonsmokers, with heavy smokers
having rates that are four times greater than those of nonsmokers. Cigarette
smoking is the most important preventable cause of cancer in the United
