We study long ago from the internet that smoking make cause:

✖Bad skin
✖Bad breath
✖Bad-smelling clothes and hair
✖Reduced athletic performance
✖Greater risk of injury and slower healing time
✖Increased risk of illness

here are the information given:

✖Bad skin. Because smoking restricts blood vessels, it can prevent oxygen and nutrients from getting to the skin - which is why smokers often appear pale and unhealthy. An Italian study also linked smoking to an increased risk of getting a type of skin rash called psoriasis.

✖Bad breath. All those cigarettes leave smokers with a condition called halitosis, or persistent bad breath.

✖Bad-smelling clothes and hair. The smell of stale smoke tends to linger - not just on people's clothing, but on their hair, furniture, and cars. And it's often hard to get the smell of smoke out.

✖Reduced athletic performance. People who smoke usually can't compete with nonsmoking peers because the physical effects of smoking - like rapid heartbeat, decreased circulation, and shortness of breath - impair sports performance.

✖Greater risk of injury and slower healing time. Smoking affects the body's ability to produce collagen, so common sports injuries, such as damage to tendons and ligaments will heal more slowly in smokers than nonsmokers.

✖Increased risk of illness. Studies show that smokers get more colds, flu, bronchitis, and pneumonia than nonsmokers. And people with certain health conditions, like asthma, become more sick if they smoke (and often if they're just around people who smoke). Because teens who smoke as a way to manage weight often light up instead of eating, their bodies lack the nutrients they need to grow, develop, and fight off illness properly.
