2. Tobacco is a product prepared from the
leaves of the tobacco plant . The plant is
categorized within the genus Nicotiana
of the Solanaceae. Tobacco contains the
alkaloid nicotine, a stimulant. Dried
tobacco leaves are mainly smoked in
cigarettes, cigars, pipe tobacco, and
Mu'assel . They are also consumed as

tobacco.
3. History of tobacco
• Tobacco has a long history from
its usages in the early Americas.
It became increasingly popular
with the arrival of the
Europeans by whom it was
heavily traded. Following the
industrial revolution, cigarettes
were becoming popularized in
the New World as well as
Europe, which fostered yet
another unparalleled increase in
growth.
4. • Tobacco was first discovered by the
native peoples of north and south
America, The first cultivation should
take place between five thousand
and three thousand years BC and
later introduced to Europe and the
rest of the world. Tobacco had
already long been used in the
Americas by the time European
settlers arrived and introduced the
practice to Europe, where it became
popular. At high doses, tobacco can
become hallucinogenic; accordingly,
Native Americans did not smoke
tobacco recreationally.
5. • By order of Philip II, the physician
and botanist Francisco Hernández
de Boncalo was who brought the
first seeds of snuff to reach Europe
in 1577. These seeds were planted
around Toledo, in an area called
the Cigarrales because they used
to be invaded by plagues of
locusts. There snuff cultivation
began in Europe and, for this
reason, some historians associate
the name of the cigar with these
farms.
6. • The tobacco is not a health
problem until the Industrial
Revolution, at which mass
production began.
Advertising, mainly in
children and young people,
became his role model and
has issued several negative
messages.
7. Damage to health
• The most common diseases associated with
smoking are bronchitis and emphysema.
Nicotine also has a direct effect on the
vascular system and can cause gangrene. It
considers that cigarette smoking can
negatively impact male sexual potency.
The rules of snuff so far only covers the limits
on nicotine, tar and carbon monoxide.
However, according to various investigations
it has been discovered around 4,000
chemicals, of which about 40 of them can be
carcinogenic to humans.
8. Nicotine is considered the chemical that causes the addiction to cigarettes. Some
statistics show that nicotine is as addictive as cocaine.
Arsenic: is an extremely toxic chemical, normally used as rat poison compound.
Tar is a cause of cancer and that by inhaling the cigarette that is deposited in the
lungs.
Ammonia: is a colorless gas with a characteristic odor, more commonly known as a
component of cleaning products.
Butane: used, inter alia, as domestic fuel for warmth or cooking stoves.
Methane: rocket fuel.
Cadmium: in batteries.
Carbon monoxide: carbon monoxide, which can also be found in the smoke from car
exhaust is the most harmful to pregnant women because it limits the oxygen in the
body.

dioxide) and passive smokers are more
likely to develop pneumonia, chronic
bronchitis, etc. The adverse effects and
damages both active smokers and
passive the Respiratory.
10. NICOTIANA
Many species of tobacco are in the genus of
herbs Nicotiana. It is part of the
nightshade family (Solanaceae) indigenous
to North and South America,Australia, south
west Africa, and the South Pacific.
Many plants contain nicotine, a
powerful neurotoxin to insects. However, tobaccos
contain a higher concentration of nicotine than most
other plants. Unlike many other Solanaceae species,
they do not contain tropane alkaloids, which are often
poisonous to humans and other animals.
11. Despite containing enough nicotine and other compounds such
as germacrene and anabasine and other piperidine alkaloids (varying between
species) to deter most herbivores, a number of such animals have evolved the
ability to feed on Nicotiana species without being harmed. Nonetheless, tobacco is
unpalatable to many species, and accordingly some tobacco plants (chiefly N.
glauca) have become established as invasive weeds in some places.
