A new study has released information that makes smoking cigarettes out to be even more dangerous for ones health than previously thought. Smoking has for a long time been considered responsible for 21 different disease including 12 different types of cancer, but now five more diseases have now been added to the list.

That also means that anywhere from 60,000 to 120,000 more deaths each year can be attributed to cigarette smoking than previously considered.

The findings for this study were collected by collecting data on health from a million people over a ten year period. Researchers found that in addition to the more commonly associated diseases with smoking cigarettes, smoking can also be blamed for higher rates of general infection, kidney disease, intestinal disease, heart issues, and lung issues besides just cancer.

According to the Centers for Disease Control and Prevention about 42 million Americans are currently cigarette smokers. On average smokers die about ten years earlier than non smokers, and the death rate of smokers is two to three times higher in general than the average non smoking person.

The research found that people who smoked were twice as likely as non smokers to die due to an infection, respiratory issues, and kidney disease. Smoking lowers the immune system in general and can reduce the blood flow in certain areas of the body which makes it challenging for the body to take care of itself in general and to heal when something goes wrong.

The study also found that the more often or more heavily a smoker smoked, the more they raised their risks of developing diseases associated with smoking. The good news is that the more time that goes by after someone stops smoking, the more their risks decrease.

Coauthor Eric Jacobs spoke to Reuters Health about the study.

“We were interested in whether smoking causes more than these diseases that are on the list. And we certainly did find some. The fact that about 17 percent of the extra deaths that occur in smokers were due to causes that were not on the Surgeon General’s list was a bit of a surprise to me,” he said.
