FACTS ABOUT NICOTINE
- Nicotine
is from the tobacco plant which is a native of Central and South America.
It serves the plant as an insecticide. It is one of the world’s
most poisonous plants and one of the most addictive. It is not a pure stimulant as it
stimulates some nerves and paralyses others. It has no medical uses. It can be smoked, chewed or placed
between the lip and gum as with snuff.
Smoking is most popular.
- The
user, most commonly a smoker, feels alert but has some muscle
relaxation. Nicotine increases the
heart rate, raises the blood pressure and causes blood clotting.
- Tobacco
use is associated with a long list of diseases including chronic
bronchitis, heart attacks and lung cancer.
.
- New
users often suffer nausea and vomiting, increased saliva and bronchial
secretions, With continued use this passes and is replaced by addiction and
withdrawal symptoms when abstinence is forced or chosen.
- The
average cigarette has 8 to 9
mg. of nicotine but delivers approximately 1 mg. to the smoker.
- Paternal
smoking effects the production of his male hormones and thus effects the
sperm. This may cause decreased
fertility and miscarriage even when the mother does not smoke. Second hand
smoke also plays a role in miscarriage.
- Maternal
use during pregnancy causes abnormal placenta, low birth weight, and birth
defects.
- After
birth nicotine also interferes with the production of breast milk.
- Babies
exposed to second hand smoke have more respiratory problems such as
bronchitis, wheezing and chronic cough.
- Smoking
is steadily decreasing in most of the population. However, it is increasingly
associated with poorly educated and low income populations and even more
so with mental illness.
- Withdrawal
symptoms include irritability, impatience, hostility, anxiety, depression,
poor concentration, decreased heart rate and weight gain. It is difficult but not life
threatening.
- Most
users who want to quit do better with combined counseling/social support
and medications such as Clonidine, bupropion (Zyban), and sometimes by
naloxone (Narcan). Nicotine gum or
patches also helps some people.
