Smoking is the practice of inhaling smoke from burning plant material. Nicotine works on your brain to create a relaxing, pleasurable feeling that makes it tough to quit.

Smoking is when you inhale and exhale smoke from burning plant material that’s rolled into a wrapper (cigarette). You light the end of the cigarette and pull smoke into your mouth through the other end. It travels down your airways, into your lungs and though your bloodstream to your brain and other organs. This piece focuses on smoking tobacco cigarettes, but you can also smoke cigars, pipes, marijuana (weed/pot) or herbal cigarettes.

 

Dangerous chemicals in tobacco smoke

Highly damaging components of tobacco smoke include:

•     Tar –

   Is the word for the solid particles suspended in tobacco smoke. The particles contain chemicals, including cancer-causing substances (carcinogens). Tar is sticky and brown, and stains teeth, fingernails and lung tissue.

• Carbon monoxide– 

Is a poisonous gas. It is odourless and colourless and, in large doses, quickly cause death because it takes the place of oxygen in the blood. In people who smoke, the carbon monoxide in their blood makes it harder for oxygen to get to their organs and muscles.

•  Oxidizing chemicals –

Are highly reactive chemicals that can damage the heart muscles and blood vessels of people who smoke. They react with cholesterol, leading to the build-up of fatty materials and artery walls. Their actions lead to heart disease, stroke and blood vessel disease.

• Metals – 

Tobacco smoke contains several metals that cause cancer, including arsenic, beryllium, cadmium, chromium, cobalt, lead and nickel.

• Radioactive compounds –

tobacco smoke contains radioactive compounds that are known to carcinogenic.

If you’re pregnant, it travels to the fetus

Narrowed blood vessels in the placenta and umbilical cord restrict blood flow to the fetus. The blood that does flow through carries carbon monoxide, nicotine and other harmful chemicals. This can prevent the fetus from getting enough oxygen and damage its DNA. Women who smoke while they’re pregnant are more likely to have a miscarriage. Babies born to someone who smokes can have low birth weight, heart and lung issues, and development delays.

Why do people smoke?

People smoke because they find it enjoyable. And because it’s hard to quit once you start, despite the damaging effects of smoking on your body. This is because of your brain’s cravings for nicotine, which makes you feel bad when you don’t get it.

Nicotine releases chemicals in your brain that make you feel good. Smoking might make you feel:

• Relaxed and calm.
• Buzzed and energized.
• More able to focus on tasks.

Smoking is also social activity and a part of people’s routine, just like morning coffee. You might smoke you fun, to calm yourself before being around a lot of people, or to focus and work. Some people like the taste for just the feeling of holding a cigarette in their hands.
