Smoking is the Primary Cause of Evitable Death in the US

Abstract

Cigarette smoking causes harm to almost every organ of human body, reduces life span, and worsens life quality of a smoker in general. Every day, about 1,000 children and teenagers take up this dreadful habit in the US only. About 20% of the adults are the active smokers in spite of the fact that cigarette smoking is the primary cause of evitable death in the US. The habit takes the lives of 443,000 people every year, which makes smoking the most critical issue nowadays.

 

Nicotine is a Drug

Giving up cigarette smoking is not easy, because nicotine is a drug, officially recognized as such in 1997. Being a stimulant, it triggers the center of the human brain responsible for reward and pleasure, leads to dependency and addiction. Nicotine incentivizes the formation and release of dopamine in the brain and adds to the good feeling. Nicotine withdrawal symptoms include headache, irritability, insomnia, increased hunger, depression, craving for sweets, problems with blood pressure and digestive system. Regretfully, every year, 30 million US citizens try to give up smoking and fail.

Any pleasure one may get from smoking is not worth the inevitable consequences; up to 87% of deaths from lung cancer are caused by smoking.

Underweight babies are born with undeveloped lungs, which leaves children not only with the high risk of asthma, but also endangers them to other long-term lung problems. Heart defects and lifelong brain disorders such as low IQ, behavioral and learning problems are other horrible consequences of smoking while pregnant.

Summary

People should never soothe themselves with the idea that once they give up smoking, their health will recover completely in a while, their lungs will clean up, and they will avoid all the death risks. The risk is never eliminated. In five years from quitting smoking, risk of dying from mouth, throat, esophagus, and bladder cancer drops by half. The risk of developing lung cancer drops to the same level in ten years only. Still, giving up the devastating habit is efficient at every point, even if one was diagnosed with the lung cancer already. Smoking worsens the body’s ability to heal and react to medication, which affects the chances for recovery.
