Smoking is when someone breathes in smoke from burning tobacco. This can be done by having a cigarette, cigar, or pipe. When someone smokes, they inhale toxic chemicals like tar, nicotine, and carbon monoxide that can make them sick. It can be dangerous and harmful for their health, like developing lung cancer, heart disease, and other illnesses.
When someone inhales smoke, the toxic chemicals get into their body and can cause damage to their organs. The nicotine in tobacco makes people feel good and makes them addicted to smoking. This means they want to keep smoking even though it's not good for them.
Smoking can also be bad for people around the smoker. Secondhand smoke is when someone breathes in the smoke that a smoker exhales. This can also cause health problems for those nearby, like children, friends, and family members who don't smoke.
It's important to remember that smoking is not good for your health and can make it easier to get sick. It's best not to start smoking, but if you do smoke, it's important to try to quit as soon as possible to improve your health.
