Tobacco
Effects on the body
Central nervous system
-
increases risk of muscular degeneration, cataracts, and poor eyesight. It can also weaken your sense of taste and sense of smell
Your body has a stress hormone called corticosterone, which lowers the effects of nicotine. If you’re under a lot of stress, you’ll need more nicotine to get the same effect.
Physical withdrawal from smoking can impair your cognitive functioning and make you feel anxious, irritated, and depressed. Withdrawal can also cause headaches and sleep problems.
Respiratory
Your lungs lose their ability to filter harmful chemicals. So these toxins get trapped in the lungs. Smokers have a higher risk of respiratory infections, colds, and flu.
Higher risk for lung diseases such as emphysema, chronic bronchitis, and COPD (coronary obstructive pulmonary disease) and even lung cancer.
Withdrawal from tobacco products can cause temporary congestion and respiratory pain as your lungs begin to clear out.
Cardivascualar system
When nicotine hits your body, it gives your blood sugar a boost. After a short time, you’re left feeling tired and craving more.
Nicotine causes blood vessels to tighten, which restricts the flow of blood (peripheral artery disease).
Smoking lowers good cholesterol levels and raises blood pressure, which can result in stretching of the arteries and a buildup of bad cholesterol (atherosclerosis).

Skin, Hair, and Nails (Integumentary System)
Smoking causes skin discoloration, wrinkles, and premature aging.

Digestive Sytem
Tobacco use can cause gum inflammation (gingivitis) or infection (periodontitis). These problems can lead to tooth decay, tooth loss, and bad breath.
Increases risk of cancer of the mouth, throat, larynx, and esophagus. Even cigar smokers who don’t inhale are at increased risk of mouth cancer.
-
Smoking also has an effect on insulin, making it more likely that you’ll develop insulin resistance. That puts you at increased risk of type 2 diabetes.
Smoking also depresses appetite, so you may not be getting all the nutrients your body needs. Withdrawal from tobacco products can cause nausea.
