I like it.

Perfection is such a nuisance that I often regret having cured myself of using tobacco.
Emile Zola

 

If alcohol is queen, then tobacco is her consort. It’s a fond companion for all occasions, a loyal friend through fair weather and foul. People smoke to celebrate a happy moment, or to hide a bitter regret. Whether you’re alone or with friends, it’s a joy for all the senses. What lovelier sight is there than that double row of white cigarettes, lined up like soldiers on parade and wrapped in silver paper? I love to touch the pack in my pocket, open it, savor the feel of the cigarette between my fingers, the paper on my lips, the taste of tobacco on my tongue. I love to watch the flame spurt up, love to watch it come closer and closer, filling me with its warmth.”

Luis Buñuel

 

Never slap a man who chews tobacco

 Willard Scott quotes

 

Tobacco: Aromatic means of lining the pockets of the manufacturer, the lungs of the consumer and the boxes of the undertaker- Author Unknown

Why Tobacco Gives the Kick?

November 11, 2007 · 1 Comment

What is Tobacco?

Tobacco comes from the leaves of the tobacco plant (Nicotiana tabacum and Nicotiana rustica), which contain nicotine. Nicotine is a stimulant drug. Stimulant drugs act on the central nervous system to speed up the messages traveling between the brain and the body. The leaf of the tobacco plant is dried, cured and aged before having other ingredients added to manufacture a range of tobacco-based products. For example, cigarettes (including some herbal cigarettes), cigars, pipe tobacco, chewing tobacco, and wet and dry snuff.

 

What Tobacco Does?

Nicotine is highly addictive and acts as both a stimulant and a sedative to the central nervous system. The ingestion of nicotine results in an almost immediate “kick” because it causes a discharge of epinephrine from the adrenal cortex. This stimulates the central nervous system, and other endocrine glands, which causes a sudden release of glucose. Stimulation is then followed by depression and fatigue, leading the abuser to seek more nicotine.

 

Immediate Effects?

Soon after smoking, chewing or snuffing tobacco, the following effects may be experienced:

  • initial stimulation, then reduction in brain and nervous system activity
  • enhanced alertness and concentration
  • mild euphoria
  • feelings of relaxation
  • increased blood pressure and heart rate
  • decreased blood flow to body extremities like the fingers and toes
  • dizziness, nausea, watery eyes and acid in the stomach
  • decreased appetite, taste and smell.

Tobacco Dependence?

People who use tobacco tend to develop a tolerance to the effects of the nicotine in the tobacco very quickly. This means they need to smoke more and more in order to get the same effect.

With repeated use of tobacco, the risk of dependence on nicotine is high. Dependence on nicotine can be physiological, psychological or both.

People who are physically dependent on nicotine find their body has become used to functioning with the nicotine present and may experience withdrawal symptoms when they reduce their nicotine intake.

People who are psychologically dependent on nicotine may find they feel an urge to smoke/ Chew/ Snuff when they are in specific surroundings, such as at the pub, or in particular situations such as during their lunch break or socialising with friends.

Research has shown that smoking is often associated with different roles and meanings for smokers, including:

  • social roles—such as enjoyment of the company of friends, the drinking of coffee or alcohol, and promoting social confidence and feelings of independence (particularly for young women)
  • emotional roles—caring for the self, such as helping to deal with stress and anxiety, weight control and providing “companionship”
  • temporal roles—such as connecting the flow of events or time in the smoker’s day, providing a break from work or activities and relieving boredom.

What’s in a Cigarette Smoke?

There are more than 4000 chemicals in tobacco smoke. Many of these chemicals are poisonous and at least 43 of them are carcinogenic (cause cancer). The three major chemicals in tobacco smoke are:

  • Nicotine—the chemical on which smokers become dependent
  • Tar—which is released when a cigarette burns
  • Carbon monoxide (CO)—a colourless, odourless and very toxic gas that is taken up more readily by the lungs than oxygen. Smokers typically have high levels of CO in the blood.

This may be why smoking is sometimes referred to as the most difficult drug to give up !

The hot things !

chili

Capsaicin is the ingredient found in different types of peppers, such as cayenne peppers, that makes the peppers hot. Capsaicin is trans-8-methyl-N-vanillyl-5 nonenamide, a naturally occurring alkyl vanillylamide and a type of capsaicinoid. Capsaicin and several related compounds are called capsaicinoids and are produced as a secondary metabolite by certain plants of the genus Capsicum (chile peppers), probably as deterrants against herbivores. There are two main capsaicinoids, capsaicin and dihydrocapsaicin and three minor capsaicinoids, nordihydrocapsaicin, homocapsaicin and homodihydrocapsaicin.

The chili pepper, red pepper and paprika are all species of capsicum. Capsicum is the dry powder obtained by grinding up the fruits of these plants. Capsicum oleoresin (or capsaicin oleoresin) is the liquid concentrate extracted from the dry powder. Capsicum has recently been officially defined in the USP 23 where it is defined as the dried ripe fruit of Capsicum frutescens Linne or Capsicum annum Linne. Capsaicin is the most pungent of the capsaicinoids, followed by dihydrocapsaicin. Pure capsaicin is a lipophilic colorless odorless crystalline to waxy compound. It is very soluble in fats, oils and alcohols. Capsicum also contains a red coloring matter, oleic acid, palmitic acid and stearic acid.

Capsaicin health benefits

Capsaicin is used in topical ointments to help relieve a certain type of pain known as neuralgia. Capsaicin is also used to temporarily help relieve the pain from osteoarthritis or rheumatoid arthritis. Neuralgia is a pain from the nerves near the skin
surface. This pain may occur after an infection with herpes zoster (shingles). It may also occur if you have diabetic neuropathy. Diabetic neuropathy is a condition that occurs in some persons with diabetes. The condition causes tingling and pain in the feet and toes. Capsaicin will help relieve the pain of diabetic neuropathy, but it will not cure diabetic neuropathy or diabetes. Capsaicin works by first stimulating and then decreasing the intensity of pain signals in the body. Substance P is believed to be involved in two processes central to arthritis. By blocking the production and release of substance P, capsaicin can reduce the pain associated with arthritis as well as dampen the transmission of pain messages to the brain.

Capsaicin acts as an antioxidant, protecting the cells of the body from damage by harmful molecules called free radicals. Capsaicin also may help prevent bacterial infections. When peppers are eaten or taken as a dietary supplement, capsaicin may improve digestion by increasing the digestive juice in the stomach and by fighting bacteria that could cause an infection. Capsaicin may help prevent heart disease. It may stimulate the cardiovascular system and lower blood cholesterol levels and blood pressure. It also helps prevent clotting and hardening of arteries (atherosclerosis). Capsaicin may also thin mucus and help move it out of the lungs. It is also thought to strengthen lung tissues and help to prevent or treat emphysema
