 The Effects of Smoking on Human Health

The effects of smoking on human health are serious and in many cases, deadly. There are approximately 4000 chemicals in cigarettes, hundreds of which are toxic. The ingredients in cigarettes affect everything from the internal functioning of organs to the efficiency of the body's immune system. The effects of cigarette smoking are destructive and widespread.

Smoking Effects on the Human Body:~

• Toxic ingredients in cigarette smoke travel throughout the body, causing damage in several different ways.
• Nicotine reaches the brain within 10 seconds after smoke is inhaled. It has been found in every part of the body and in breast milk.
• Carbon monoxide binds to hemoglobin in red blood cells, preventing affected cells from carrying a full load of oxygen.
• Cancer-causing agents (carcinogens) in tobacco smoke damage important genes that control the growth of cells, causing them to grow abnormally or to reproduce too rapidly.
• The carcinogen benzo(a)pyrene binds to cells in the airways and major organs of smokers.
• Smoking affects the function of the immune system and may increase the risk for respiratory and other infections.
• There are several likely ways that cigarette smoke does its damage. One is oxidative stress that mutates DNA, promotes atherosclerosis, and leads to chronic lung injury. Oxidative stress is thought to be the general mechanism behind the aging process, contributing to the development of cancer, cardiovascular disease, and COPD.
• The body produces antioxidants to help repair damaged cells. Smokers have lower levels of antioxidants in their blood than do nonsmokers.
• Smoking is associated with higher levels of chronic inflammation, another damaging process that may result in oxidative stress.

 

The Health Risks of Smoking

Do you have any idea which smoking-related disease is the number one cause of death among smokers? If you're thinking it's lung cancer or COPD/emphysema, you're wrong. While both of these smoking-related diseases do claim a lot of lives, it is heart disease that that holds the top slot in the list of diseases that kill smokers.

Heart disease is the leading cause of death in the United States today, and the leading cause of death among smokers. And, on a global level, researchers report that there were 1,690,000 premature deaths from cardiovascular disease among smokers in the year 2000. In contrast, there were approximately 850,000 lung cancer deaths during the same year, and 118,000 COPD deaths from smoking in 2001, worldwide.
Smoking is hard on the heart, but the fact is, tobacco use plays a role in a multitude of diseases that ultimately lead to disability and/or death. Cigarette smoke contains over 4,000 chemical compounds; 200 of which are known to be poisonous, and upwards of 60 have been identified as carcinogens. Viewed in that light, it's no wonder that the effects of smoking are so widespread and destructive.
Let's take a look at how cigarette smoke affects our bodies, from head to toe. You may be surprised at some of the ways smoking has a negative impact on our health.

The effects of smoking hold additional risks for women. Those who smoke throughout their pregnancies increase the risk of:

• Spontaneous abortion/miscarriage
• Ectopic pregnancy
• Abruptio placentae
• Placenta previa
• Premature rupture of the membranes
• Premature birth

Risks to the fetus include:

• Smaller infant(for gestational age)
• Stillborn infant
• Birth defects, e.g. congenital limb reduction
• Increased nicotine receptors in baby's brain
• Increased likelihood of child smoking as a teenager
• Possible predisposition to adult anxiety disorders

As long as this list of diseases known to be associated with smoking is, it is incomplete. We don't yet fully understand all of the dangers that cigarette smoke presents, but research continues, bringing us new discoveries seemingly by the day. One thing is certain: Cigarettes snuff out life at an alarming rate. Statistics tell us that upwards of half of long-term smokers will die a smoking-related death. And globally, that presently translates to nearly 5 million deaths a year. Put another way, someone loses their life to smoking every 8 seconds somewhere in the world.
