Tobacco use- a serious health risk Smoking is the #1 cause of preventable disease and death in the united states. Because of the high health risk, there are warning labels on all tobacco products. Everyday, still with those, teens begin to smoke, chew or dip tobacco. Many begin thinking they can quit whenever they want… when in reality, it is extremely hard to quit. Tobacco can be described as addictive, stimulant and carcinogen

nicotine One reason tobacco users find it so difficult to quit is due to addictive drug: a substance that causes physiological dependence. All tobacco products contain nicotine: the addictive drug found in tobacco leaves. This is also classified as a stimulant: a drug that increases the action of the central nervous system, the heart and the organs.

Cigarette smoke- a tobacco mixture Did you know the smoke from burning tobacco is toxic? In 1992, the environmental protection agency classified environmental tobacco, or secondhand smoke, as a group A carcinogen. A carcinogen is a cancer-causing substance. Do you ever experience second-hand smoke?

Tar and carbon monoxide Cigarette smoke contains tar, a thick, sticky dark fluid produced when tobacco burns. As tar penetrates the smokers respiratory system, it destroys cilia, tiny hairlike structures that line the upper airways and protect against infection. Tar damages the air sacs, which absorbs oxygen and rid the body of carbon dioxide. It also destroys lung tissues, making the lungs less able to function.

Harmful effects of pipes and cigars Cigars contain significantly more nicotine and produce more tar and carbon monoxide (colorless, odorless and poisonous gas) than cigarettes do. One cigar contains as much nicotine as a pack of cigarettes!!

Harmful effects of smokeless tobacco Smokeless tobacco is tobacco that is sniffed through the nose, held in the mouth, or chewed. Like tobacco that is smoked, smokeless tobacco contains nicotine in addition to 28 carcinogens. Smokeless tobacco is addictive and also releases more carcinogens than cigarettes. It can cause cancer of the mouth and stomach.

How tobacco affects the body

Short term effects of tobacco use The brain, lungs and stomach are all areas affected by smoking. Changes in brain chemistry: nicotine causes the body to crave more. The user may experience withdrawal symptoms like headaches, nervousness, and trembling as soon as 30 minutes after the last use. Increased respiration and heart rate: breathing during physical activity becomes more difficult. Could cause irregular heart rate.

Short term effects of tobacco use Dulled taste buds and reduced appetite: they often lose much of their ability to enjoy food due to losing taste buds Bad breathe and smelly hair, clothes and skin … JUST YUCK!

Long-term effects of tobacco use Chronic bronchitis: repeated tobacco use can damage the cilia in the bronchi until it no longer functions. This leads to buildup of tar in the lungs, causing coughing and excessive mucus secretion. Emphysema: this is a disease that destroys the tiny air sacs in the lungs. The air sacs become less elastic, making it more difficult for the lungs to absorb oxygen. That means you use up to 80% of your energy just to breathe.

Lung cancer Lung cancer: when cilia in bronchi are destroyed, extra mucus cannot be expelled. Cancerous cells then grow in these conditions causing lung cancer. Coronary heart disease and stroke: nicotine restricts blood vessels, which cuts down on circulation, or blood flow. Arteries then get clogged, increasing the risk of heart attack and stroke.

Other consequences of smoking Legal consequences: selling tobacco products to persons under the age 18 is illegal in all states. Social consequences: many people find secondhand smoke and the smell offensive, so the users may be excluded from social gatherings. Financial consequences: use of tobacco products can be very expensive. Someone who smokes a pack of cigarettes a day can spend more than $2,000 a year just on cigarettes.
