Cigarettes are Addictive and Infectious

Everyone knows cigarettes are extremely dangerous and addictive.

An American researcher wanted to also draw attention to how infectious the tobacco in cigarettes is, as the substance is laden with bacteria.

In fact, there is so much bacteria present in tobacco, Amy Sapkoto believes the number of germs could certainly be compared to the number of toxic chemicals and carcinogens that have been isolated.

The Theory

Environmental scientist from the University of Maryland, Amy Sapkota, conducted a study that looked at the bacteria found in tobacco and whether or not these bacteria could possibly be a source of infection for a person who comes in contact with it. Sapkota conjectured that simply touching a cigarette or putting one unlit in the mouth can encourage an impairment of bodily functions.

Types of Bacteria Found

The researchers examined the genetic makeup of the bacteria they were able to isolate from the tobacco under sterile conditions. The genetic material of almost 800 different bacteria was compared to the bacteria in the four most smoked brands of cigarettes in Western countries: Marlboro Red, Camel, Kool Filter Kings, and Lucky Strike Original Red.

A few of the bacteria found in the cigarettes researched in this study include:

  • Campylobacter, a germ leading to food poisoning and Guillan-Barre Syndrome;
  • Clostridium, another germ causing food poisoning as well as leading to pneumonia;
  • Corynebacterium, another pneumonia-triggering bacteria;
  • E.Coli;
  • Klebsiella, associated with pneumonia and urinary tract infections;
  • Pseudomonas aeruginosa, another bacteria also associated to cases of pneumonia and urinary tract infections;
  • Stenotrophomonas maltophilia, a third bacteria playing a part in pneumonia and urinary tract infections; and
  • several staphylococcus species.

Infectious Bacteria

Cigarettes and BacteriaSapkota doesn’t heed attention to claims that a burning cigarette would kill any bacteria present in the tobacco.

Instead, she theorizes that the cigarette smoke picks up bacteria as it is inhaled, and deposits it into the smoker’s lungs. From here, the bacteria thrives and contributes to the formation of disease.

5 Lung Cancer Symptoms Most People Don’t Know About

If you are wondering what symptoms of lung cancer might feel like, here is a list to look out for if you are a smoker or ex smoker.

Shoulder or upper back pain: Pain in the shoulder or upper back is a often unnoticed lung cancer symptom. The pain results from a tumor pressing on the lining of the lungs.

Swelling of the face and neck is also a lung cancer symptom: Tumors can often put pressure of blood vessels, not allowing fluids to to travel as efficiently throughout the body. The fluids then build up, causing swelling of the face and neck.

Frequently getting pneumonia is also a symptom of lung cancer.

Male breast development: Gynecomastia is the over development of the male breast and can be a symptom of lung cancer in men. Breast growth in men is normally due to the increase of estrogen. Lung cancer has been known to produce estrogen.

Hoarseness: Do you constantly feel like you have to clear your throat or your throat feels hoarse. This is a very common symptom of lung cancer. Lung cancer tumor cells can block passageways leading to many symptoms, like hoarseness.

More About Lung Cancer: If you are experiencing the symptoms of lung cancer, please see your doctor. Keep in mind that these symptoms of lung cancer are also the symptoms of many other benign condition.
