Nicotine Dependence; Symptoms, Causes, Complication, Treatment And Prevention.

images (25)Nicotine dependence — also called tobacco dependence — is an addiction to tobacco products caused by the drug nicotine. Nicotine dependence means you can’t stop using the substance, even though it’s causing you harm.

Nicotine produces physical and mood-altering effects in your brain that are temporarily pleasing. These effects make you want to use tobacco and lead to dependence. At the same time, stopping tobacco use causes withdrawal symptoms, including irritability and anxiety.

While it’s the nicotine in tobacco that causes nicotine dependence, the toxic effects of tobacco result from other substances in tobacco. Smokers have much higher rates of heart disease, stroke and cancer than nonsmokers do.

Regardless of how long you’ve smoked, stopping smoking can improve your health. Many effective treatments for nicotine dependence are available to help you manage withdrawal and stop smoking for good. Ask your doctor for help.

Symptoms
In some people, using any amount of tobacco can quickly lead to nicotine dependence. Signs that you may be addicted include:

You can’t stop smoking. You’ve made one or more serious, but unsuccessful, attempts to stop.

You experience withdrawal symptoms when you try to stop. Your attempts at stopping have caused physical and mood-related signs and symptoms, such as strong cravings, anxiety, irritability, restlessness, difficulty concentrating, depressed mood, frustration, anger, increased hunger, insomnia, constipation or diarrhea.

You keep smoking despite health problems. Even though you’ve developed problems with your lungs or your heart, you haven’t been able to stop.

You give up social or recreational activities in order to smoke. You may stop going to smoke-free restaurants or stop socializing with certain family members or friends because you can’t smoke in these locations or situations

Causes
Nicotine is the chemical in tobacco that keeps you smoking. Nicotine is very addictive when delivered to the lungs by inhaling tobacco smoke. It increases the release of brain chemicals called neurotransmitters, which help regulate mood and behavior. One of these neurotransmitters is dopamine, which may improve your mood and activate feelings of pleasure. Experiencing these effects from nicotine in tobacco is what makes tobacco so addictive.

Nicotine dependence involves behavioral as well as physical factors. Behaviors and cues that you may associate with smoking include:

Certain times of the day, such as first thing in the morning, with morning coffee or during breaks at work

After a meal

Drinking alcohol

Certain places or friends

Talking on the phone

Stressful situations or when you’re feeling down

Sight or smell of a burning cigarette

Driving your car

To overcome your dependence on tobacco, you need to deal with the behaviors and routines that you associate with smoking.

Complication
Smoking harms almost every organ of your body, and more than 60 percent of people who keep smoking will die because of it. Women smokers are now at equal risk to men smokers of dying from diseases caused by using tobacco. The negative health effects include:

Lung cancer and other lung diseases. Smoking causes nearly 9 out of 10 lung cancer cases, as well as other lung diseases, such as emphysema and chronic bronchitis. Smoking also makes asthma worse.

Heart and circulatory system problems. Smoking increases your risk of dying of heart and blood vessel (cardiovascular) disease, including heart attack and stroke.

Diabetes. Smoking increases insulin resistance, which can set the stage for the development of type 2 diabetes. If you have diabetes, smoking can speed the progress of complications, such as kidney disease and eye problems.

Eye problems. Smoking can increase your risk of serious eye problems such as cataracts and loss of eyesight from macular degeneration.

Infertility and impotence. Smoking increases the risk of infertility in women and the risk of impotence in men.

Pregnancy and newborn complications. Mothers who smoke while pregnant face a higher risk of miscarriage, preterm delivery, lower birth weight and sudden infant death syndrome (SIDS) in their newborn.

Cold, flu and other illnesses. Smokers are more prone to respiratory infections, such as colds, flu and bronchitis.

Weakened senses. Smoking deadens your senses of taste and smell, so food isn’t as appetizing.

Teeth and gum disease. Smoking is associated with an increased risk of developing inflammation of the gum (gingivitis) and a serious gum infection that can destroy the support system for teeth (periodontitis).

Physical appearance. The chemicals in tobacco smoke can change the structure of your skin, causing premature aging and wrinkles. Smoking also yellows your teeth, fingers and fingernails.

Risks to your family. Nonsmoking spouses and partners of smokers have a higher risk of lung cancer and heart disease compared with people who don’t live with a smoker. If you smoke, your children will be more prone to SIDS, worsening asthma, ear infections and colds.

Treatment
Like most smokers, you’ve probably made at least one serious attempt to stop. But it’s rare to stop smoking on your first attempt — especially if you try to do it without help. You’re much more likely to stop if you use medications and counseling, which have both been proved effective, especially in combination. Your doctor would recommend the appropriate treatment and counselling for you.

Prevention
The best way to prevent tobacco dependence is to not smoke in the first place. The best way to prevent your children from smoking is to not smoke yourself. If you are a parent who smokes, the younger your children are when you quit, the less likely they are to become smokers themselves.

Even if you don’t smoke, here are some things you might try as a parent:

Promote smoke-free environments. Support legislation to make all workplaces smoke-free. Encourage smoke-free public places, including restaurants or other places where your teen may work.

Support legislation to increase taxes on tobacco products. Higher prices discourage teens from starting to smoke. Higher prices on tobacco products, coupled with smoke-free workplace laws, are the most effective public health policies to reduce smoking in adults and prevent young people from ever starting.

Talk with your teenagers. Ask whether their friends smoke. Most teenagers smoke their first cigarette with a friend who already smokes. Let your child know that other forms of tobacco, including cigars and smokeless tobacco, also carry significant health risks.

Learn what your children think about smoking. Ask them to read this article so that you can discuss it together. You can be a great influence on whether your children smoke, despite what they see in movies and on the Internet.

Help your children explore personal feelings. Use nonjudgmental questions and rehearse with them how they could handle tough situations regarding peer pressure and smoking.

Note the social repercussions. Remind your teenager that smoking gives you bad breath and makes your hair and clothes smell.

Work with your schools. Become active in community and school stop-smoking programs
