Studies done in US have pointed out that smoking causes risk factors for injury including fires, depressed reflexes, non-coordination, impaired fitness and, possibly, depressed moods.

The study done by B N Leistikow, D C Martic and S J Samuels interviewed adults (ages 18 plus) and followed up for vital status after a gap of five years using the National Death Index (NDI). Participants were classified as never smokers (fewer than 100 lifetime cigarettes), ex-smokers, and current smokers (smokers by baseline self report).

For smokers, cigarettes per day were recorded into 1-14, 15-24 and 25-plus cigarettes-per-day categories.
The study found that smokers have significant dose-response excesses of injury and death, independent of age, education and marital status. This supports earlier studies suggesting that smoking may be a leading contributor to injuries.

In fact, researchers have suggested that the correlation of smoking and driving should be studied in Asia, Latin America and Africa. Also, smoking-involved crashes may be studied in the same manner as alcohol-involved crashes.

Dr Ashok Seth, chairman and chief cardiologist of Max Heart Institute, says: “This is an interesting study. Smoking and driving may lead to accidents, and smoking is a distraction – far more distractive than any activity in the car. The accidents may occur as cigarette is an inflammable object, and lead to fires.

It may make the smoker distracted and spoils his concentration with one hand constantly engaged and moving to drop the ash. Smoking is also believed to release certain hormones which pump up confidence levels, leading to errors.”

The study is of critical importance to India, where smoking is responsible for about one in 20 deaths of women and one in five deaths of men in the age group of 30-69 years. By 2010, it is estimated that smoking will lead to one million deaths in the country.

Says Dr Anoop Misra director and head, department of diabetes, Fortis Hospitals: “Tobacco smoke contains high quantity of carboxy haemoglobin, which replaces normal haemoglobin and transiently decreases oxygenation of brain.

Smoking impairs certain motor reflexes and has adverse effects on message transfer in brain due to shifts in neurochemicals.

All these would impair any complex motor task as driving. Those who are heavy smokers or relatively new smokers are worst affected. Over long periods, smoking causes permanent damage to neurons and this results in decline of intellectual functions.”

Tobacco

Botanical Name: Nicotiana tabacum
Family: Solanaceae
Genus: Nicotiana
Species: N. tabacum
Kingdom: Plantae
Order: Solanales

Synonyms:
Tabacca. Tabaci Folia (B.P.C.).
Part Used: Leaves, cured and dried.
Habitat: Virginia, America; and cultivated with other species in China, Turkey, Greece, Holland, France, Germany and most sub-tropical countries.

Description: The genus derives its name from Joan Nicot, a Portuguese who introduced the Tobacco plant into France. The specific name being derived from the Haitian word for the pipe in which the herb is smoked. Tobacco is an annual, with a long fibrous root, stem erect, round, hairy, and viscid; it branches near the top and is from 3 to 6 feet high. Leaves large, numerous, alternate, sessile, somewhat decurrent, ovate, lanceolate, pointed, entire, slightly viscid and hairy, pale-green colour, brittle, narcotic odour, with a nauseous, bitter acrid taste. Nicotine is a volatile oil, inflammable, powerfully alkaline, with an acrid smell and a burning taste. By distillation with water it yields a concrete volatile oil termed nicotianin or Tobacco camphor, which is tasteless, crystalline, and smells of Tobacco; other constituents are albumen, resin, gum, and inorganic matters.

Cultivation

Broadleaf tobacco
Tobacco plants growing in a field in Intercourse, Pennsylvania
Sowing
Tobacco seeds are scattered onto the surface of the soil, as their germination is activated by light. In colonial Virginia, seedbeds were fertilized with wood ash or animal manure (frequently powdered horse manure). Seedbeds were then covered with branches to protect the young plants from frost damage. These plants were left to grow until around April.

In the nineteenth century, young plants came under increasing attack from the flea beetle (Epitrix cucumeris or Epitrix pubescens), causing destruction of half the United States tobacco crop in 1876. In the years afterward, many experiments were attempted and discussed to control the flea beetle. By 1880 it was discovered that replacing the branches with a frame covered by thin fabric would effectively protect plants from the beetle. This practice spread until it became ubiquitous in the 1890s.

Today, in the United States, unlike other countries, tobacco is often fertilized with the mineral apatite in order to partially starve the plant for nitrogen, which changes the taste. This (together with the use of licorice and other additives) accounts for the different flavor of American cigarettes from those available in other countries. There is, however, some suggestion that this may have adverse health effects attributable to the content of apatite.

Transplanting
After the plants have reached a certain height, they are transplanted into fields. This was originally done by making a relatively large hole in the tilled earth with a tobacco peg, then placing the small plant in the hole. Various mechanical tobacco planters were invented throughout the late 19th and early 20th century to automate this process, making a hole, fertilizing it, and guiding a plant into the hole with one motion.

Harvest
Tobacco is harvested in one of two ways. In the oldest method, the entire plant is harvested at once by cutting off the stalk at the ground with a curved knife. In the nineteenth century, bright tobacco began to be harvested by pulling individual leaves off the stalk as they ripened. The leaves ripen from the ground upwards, so a field of tobacco may go through several “pullings” before the tobacco is entirely harvested, and the stalks may be turned into the soil. “Cropping”, “pulling”, and “priming” are terms for pulling leaves off tobacco. Leaves are cropped as they ripen, from the bottom of the stalk up. The first crop at the very bottom of the stalks are called “sand lugs”, as they are often against the ground and are coated with dirt splashed up when it rains. Sand lugs weigh the most, and are most difficult to work with. Originally workers cropped the tobacco and placed it on animal-pulled sleds. Eventually tractors with wagons were used to transport leaves to the stringer, an apparatus which uses twine to sew leaves onto a stick.

Some farmers use “tobacco harvesters” – basically a trailer pulled behind a tractor. The harvester is a wheeled sled or trailer that has seats for the croppers to sit on and seats just in front of these for the “stringers” to sit on. The croppers pull the leaves off in handfuls, and pass these to the “stringer”, who loops twine around the handfuls of tobacco and hangs them on a long wooden square pole. Traditionally, the croppers, down in the dark and wet, with their faces getting slapped by the huge tobacco leaves, were men, and the stringers seated on the higher elevated seats were women. The harvester has places for four teams of workers: eight people cropping and stringing, plus a packer who takes the heavy strung poles of wet green tobacco from the stringers and packs them onto the pallet section of the harvester, plus a driver, making the total crew of each harvester 10 people. Interestingly, the outer seats are suspended from the harvester – slung out over to fit into the aisles of tobacco. As these seats are suspended it is important to balance the weight of the two outside teams

(similar to a playground see-saw). Having too heavy or light a person in an unbalanced combination often results in the harvester tipping over especially when turning around at the end of a lane. Water tanks are a common feature on the harvester due to heat, and danger of dehydration for the workers. Salt tablets sometimes get used as well.

Constituents: The most important constituent is the alkaloid Nicotine, nicotianin, nicotinine, nicoteine, nicoteline. After leaves are smoked the nicotine decomposes into pyridine, furfurol, collidine, hydrocyanic acid, carbon-monoxide, etc. The poisonous effects of Tobacco smoke are due to these substances of decomposed nicotine.

Medicinal Action and Uses: A local irritant; if used as snuff it causes violent sneezing, also a copious secretion of mucous; chewed, it increases the flow of saliva by irritating the mucous membrane of the mouth; injected into the rectum it acts as a cathartic. In large doses it produces nausea, vomiting, sweats and great muscular weakness.

The alkaloid nicotine is a virulent poison producing great disturbance in the digestive and circulatory organs. It innervates the heart, causing palpitation and cardiac irregularities and vascular contraction, and is considered one of the causes of arterial degeneration.

Nicotine is very like coniine and lobeline in its pharmacological action, and the pyridines in the smoke modify very slightly its action.

Tobacco was once used as a relaxant, but is no longer employed except occasionally in chronic asthma. Its active principle is readily absorbed by the skin, and serious, even fatal, poisoning, from a too free application of it to the surface of the skin has resulted.

The smoke acts on the brain, causing nausea, vomiting and drowsiness.

Medicinally it is used as a sedative, diuretic, expectorant, discutient, and sialagogue, and internally only as an emetic, when all other emetics fail. The smoke injected into the rectum or the leaf rolled into a suppository has been beneficial in strangulated hernia, also for obstinate constipation, due to spasm of the bowels, also for retention of urine, spasmodic urethral stricture, hysterical convulsions, worms, and in spasms caused by lead, for croup, and inflammation of the peritoneum, to produce evacuation of the bowels, moderating reaction and dispelling tympanitis, and also in tetanus.

To inject the smoke it should be blown into milk and injected, for croup and spasms of the rima glottides it is made into a plaster with Scotch snuff and lard and applied to throat and breast, and has proved very effectual. A cataplasm of the leaves may be used as an ointment for cutaneous diseases. The leaves in combination with the leaves of belladonna or stramonium make an excellent application for obstinate ulcers, painful tremors and spasmodic affections. A wet Tobacco leaf applied to piles is a certain cure. The inspissated juice cures facial neuralgia if rubbed along the tracks of the affected nerve.

The quantity of the injection must never exceed a scruple to begin with; half a drachm has been known to produce amaurosis and other eye affections, deafness, etc.

The Tobacco plant was introduced into England by Sir Walter Raleigh and his friends in 1586, and at first met with violent opposition.

Kings prohibited it, Popes pronounced against it in Bulls, and in the East Sultans condemned Tobacco smokers to cruel deaths. Three hundred years later, in 1885, the leaves were official in the British Pharmacopoeia.

Externally nicotine is an antiseptic. It is eliminated partly by the lungs, but chiefly in the urine, the secretion of which it increases. Formerly Tobacco in the form of an enema of the leaves was used to relax muscular spasms, to facilitate the reduction of dislocations.

A pipe smoked after breakfast assists the action of the bowels.

The pituri plant contains an alkaloid, Pitarine, similar to nicotine, and the leaves are used in Australia instead of Tobacco. An infusion of Tobacco is generally used in horticulture as an insecticide. In cases of nicotine poisoning, the stomach should be quickly emptied, and repeated doses of tannic acid given, the person

kept very warm in bed, and stimulants such as caffeine, strychnine, or atropine given, or if there are signs of respiratory failure, oxygen must be given at once.

Smoking was once considered macho, high-class and sophisticated. James Bond, Fidel Castro and socialites smoked publicly and elegantly. Now smoking has sunk way down in the etiquette scale and is socially unacceptable. Smoking in public places such as offices, trains and movie theatres is banned in many countries including India.  Cigarette packets carry the warning: “Cigarette smoking is injurious to health. Yet, there is no serious effort to implement a 2004 law banning the sale of cigarettes to minors. As a result, 7-8 per cent of teenagers in India use tobacco, as cigarettes, beedis or as chewing tobacco.

Cigarettes are made up of finely shredded tobacco leaves and stem rolled in a special kind of paper. When smoked or chewed, tobacco provides the body with a rush of nicotine and around 600 other addictive, harmful and cancerous chemicals. These produce elation and euphoria. Eventually, the intervals between “fixes” become shorter and the number of cigarettes smoked increases.

Addiction to tobacco is both genetic and environmental. A preconditioned individual reared in a conducive environment will eventually become addicted.

As the tobacco smoke enters the lungs, it paralyses the cilia. (These are small hair-like projections from cells lining the airways and are responsible for removing foreign particles.) The smoke can then settle in the interior of the lungs, causing destruction and difficulty in breathing. Attempts to clear the material are futile and result in hacking and unproductive cough. There are repeated bacterial and viral infections. Oxygenation becomes insufficient. The person may go into heart failure and become permanently breathless.

The build up of toxins can eventually lead to cancers — in the lung, urinary tract, oral cavity, pharynx, larynx, oesophagus, pancreas, stomach and blood (acute myeloid leukaemia).

In those who do not develop cancer, tobacco damages several organs. The teeth become yellow, plaque ridden, loosened from the sockets and may eventually fall. Conversation becomes difficult because of halitosis (bad breath). The bones weaken leading to early osteoporosis.

New evidence shows that the chemicals in tobacco alter the body metabolism, precipitating glucose intolerance and the changes associated with the metabolic syndrome X. Diabetes sets in, and the lipid levels are altered. Atherosclerotic plaques build up in the blood vessels, leading to heart disease, paralysis, stroke and vascular disease. The blocks in the peripheral vessels cause pain while walking and numbness, burning and tingling in the limbs.

The IQ (intelligence quotient) falls and the smoker’s cognitive skills decline faster than in non-smokers. This makes early dementia a very real possibility.

Women who smoke during pregnancy place themselves and their foetuses at great risk. They tend to have small babies. Also, there is a much higher incidence of abnormalities of the digits in the child. Fingers and toes may be more or less than normal or stuck together.

Non-smoking men and women who live in close contact with smokers suffer all the ill effects of smoking without the pleasures of addiction. Passive smokers are the single largest international group of victims of substance abuse.

More deaths are caused each year by tobacco use than from human immunodeficiency virus (HIV), illegal drug use, alcohol consumption, motor vehicle injuries, suicides and murders combined. Smoking causes diverse and silent deaths — an unpublicised form of slow suicide. The others diseases and causes of death receive far more media publicity.

Giving up smoking is not easy. As with all other addictions, it involves reconditioning of the body and the mind. Quitting has to be abrupt and overnight. There is no slow, weaning process.

Face-to-face interactive counselling on a one-is-to-one basis is very successful in motivating people to quit.

Medication to counter the urge to smoke is available in India. The sustained-release bupropion SR is a non-nicotine drug that supposedly reduces the craving by affecting the same chemical messengers in the brain that are activated by nicotine. It is expensive, the dosage has to be individualised, and it has to be taken for a prolonged period. Motivation and persistence are usually lacking in smokers, and thus the medication has not been a success in India.

Nicotine gum is available in some of the larger cities.

Most young smokers are convinced that they have the willpower to quit whenever they want to, but in reality 90 per cent are still smoking five years later. Many sincerely believe that complications will side step them and affect others!

It is never too late. Smokers who do manage to quit get a second lease of life. On average, they live longer and are healthier than those who continue the habit.

If you want to stop, grit your teeth and “just do it”.

Betel Leaves (Paan)

[amazon_link asins=’B01AZJTX5S,B00QXVMJXQ,B01JD2LXRO,B074M8YTMT,B01L4LNPB4,B076M44RTT,B06XC37C92,B072HLX3NC,B01LXSRLWI’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’06c0d4fd-e3a1-11e7-a79b-8109740bbcf1′]

Botanical Name: Piper betel (LINN.)
Family: Piperaceae
Genus: Piper
Species: P. betle
Kingdom: Plantae
Order: Piperales


Synonyms
–:-Chavica Betel. Artanthe Hixagona

Common Name: Paan
Part Used-:–The leaves.
Habitat: The Betel plant originated in Malaysia and now grows in India, Bangladesh, Indonesia and Sri Lanka, Malaya and Java.

Description:
The plant is evergreen and perennial, with glossy heart-shaped leaves and white catkins, and grows to a height of about 1 metre. . The best Betel leaf is the “Magahi” variety (literally from the Magadha region) grown near Patna in Bihar, India. The plant is known by a series of different names in the regions in which it is consumed – among these are Vetrilai (Tamil).

The Betel plant is indigenous throughout the Indian Malay region and also cultivated in Madagascar, Bourbon and the West Indies. It is a climbing shrub and is trained on poles or trellis in a hot but shady situation. The leaves are pressed together and dried, sometimes being sewn up together in packets for commerce.

CLICK & SEE THE PICTURES
-Constituents–-The chief constituent of the leaves is a volatile oil varying in the leaves from different countries and known as Betel oil. It contains two phenols, betel-phenol (chavibetol) and chavicol. Cadinene has also been found. The best oil is a clear yellow colour obtained from the fresh leaves. The Indians use the leaves as a masticatory (the taste being warm, aromatic and bitter), together with scraped areca nut and lime.

Uses:
Chew as Mouth freshner:In India and parts of Southeast Asia, the leaves are chewed together with the mineral slaked lime (calcium hydroxide) and the areca nut which, by association, is sometimes inaccurately called the “betel nut“. The lime acts to keep the active ingredient in its freebase or alkaline form, thus enabling it to enter the bloodstream via sublingual absorption. The areca nut contains the alkaloid arecoline, which promotes salivation (the saliva is stained red), and is itself a stimulant. This combination, known as a “betel quid”, has been used for several thousand years. Tobacco is sometimes added…...CLICK &  SEE

Paan is the Hindi word (in Hindi: from Sanskrit parna ‘feather) for betel’, which is used for a stimulating and psychoactive preparation combined with areca nut and/or cured tobacco. Paan is chewed and finally spat out or swallowed. Paan has many variations. Slaked lime (chunnam) paste is commonly added to bind the leaves. Some South Asian preparations include katha paste or mukhwas  to freshen the breath.

(Katha is also known as cutch, black cutch, cachou, cashoo, khoyer, terra Japonica, or Japan earth, and also katha in Hindi, kaath in Marathi, khoyer in Assamese and Bengali, and kachu in Malay (hence the Latinized Acacia catechu chosen as the Linnaean taxonomy name of the type-species Acacia plant which provides the extract).

In India, the betel and areca play an important role in Indian culture especially among Hindus. All the traditional ceremonies governing the lives of Hindus use betel and areca. For example to pay money to the priest, they keep money in the betel leaves and place it beside the priest.

The betel and areca also play an important role in Vietnamese culture. In Vietnamese there is a saying that “the betel begins the conversation”, referring to the practice of people chewing betel in formal occasions or “to break the ice” in awkward situational conversations. The betel leaves and areca nuts are used ceremonially in traditional Vietnamese weddings. Based on a folk tale about the origins of these plants, the groom traditionally offer the bride’s parents betel leaves and areca nuts (among other things) in exchange for the bride. The betel and areca are such important symbols of love and marriage such that in Vietnamese the phrase “matters of betel and areca” (chuyện trầu cau) is synonymous with marriage.

 

-Medicinal Action and Uses:

Betel leaves are chiefly used as a gently stimulant, apparently inducing a mild sensation of well-being.  They also affect the digestive system, stimulating salivary secretions, relieving gas, and preventing worm infestation.  In many Asian traditions, including Ayurvedic medicine, betel leaves are thought to have aphrodisiac and nerve tonic properties.  In Chinese herbal medicine, betel root, leaves, and fruit are sometimes used as a mild tonic and stomach-settling herb.  The root has been used with black pepper or jequirity to produce sterility in women.

-The Betel (Piper betle) is a spice whose leaves have medicinal properties.The leaves are stimulant antiseptic and sialogogue; the oil is an active local stimulant used in the treatment of respiratory catarrhs as a local application or gargle, also as an inhalant in diphtheria. In India the leaves are used as a counter-irritant to suppress the secretion of milk in mammary abscesses. The juice of 4 leaves is equivalent in power to one drop of the oil.

In India, they use betel to cast out (cure) worms.

Betel leaves are used as a stimulant, an antiseptic and a breath-freshener Paan. In Ayurvedic medicine, they are used as an aphrodisiac. In Malaysia they are used to treat headaches, arthritis and joint pain. In Thailand and China they are used to relieve toothache. In Indonesia they are drunk as an infusion and used as an antibiotic. They are also used in an infusion to cure indigestion, as a topical cure for constipation, as a decongestant and as an aid to lactation.

In Papua New Guinea, betel is prepared with a mustard stick dipped in lime powder and acts as a stimulant to suppress hunger, reduce stress and heighten the senses.

Known Hazards: In an extensive scientific research monograph, the World Health Organization expert group for research on cancer reported in 2004 that the percentage of oral cancer among all cancers diagnosed in hospitals in Asia has always been much higher than that usually found in western countries, where the habit of chewing betel quid, with or without tobacco, is virtually unknown. In many descriptive studies, investigators have obtained histories of chewing betel quid with tobacco from series of patients with oral cancer; and in all these studies the percentage of patients who practice betel leaf chewing was found to be extremely large. Researchers also noted that the cancer generally develops at the place where the betel quid is kept. ……....CLICK & READ

The high rate of oral cancer in South Asia is thought to be due to the chewing of betel preparations; the inclusion of tobacco may worsen the risk, but there is also evidence that the areca nut, alone or as part of a betel quid, may cause cancer even without tobacco.[23] See its article for more discussion of this point.   ...CLICK & SEE

Effects of chewing paan during pregnancy:   Scientific teams from Taiwan, Malaysia and Papua New Guinea have reported that women who chew areca nut formulations, such as paan, during pregnancy significantly increase adverse outcomes for the baby. The effects were similar to those reported for women who consume alcohol or tobacco during pregnancy. Lower birth weights, reduced birth length and early term were found to be significantly higher

Some reports may suggest that betel leaf by itself has adverse health effects, in part because of tannins delivered by the leaf and for reasons currently not fully understood.   For example, one research paper studied chromosome damaging effect of betel leaf in human leukocyte cultures. These researchers report an increase in the frequency of chromatid aberrations when the leaf extract was added to cultures. Another scientific study from Japan    indicates that the lab rats who ate a mixture of betel leaf and areca nuts all had severe thickening of the upper digestive tract whereas after undergoing a diet of betel leaves alone, only one laboratory rat ended up having a forestomach papilloma.
