“While there are many habits that are deeply unhealthy, I cannot think of any that are as singularly unhealthy as cigarette smoking.”
“It also lowers your quality of life badly. It increases your risk of a host of diseases and complicates many many others. Aside from lung cancer, it aggravates the risk of cervix, colon, skin, esophagus, larynx, liver, mouth and throat, pancreatic, stomach, and leukemia cancers.
It’s awful for your risk of stroke, hypertension, or cardiovascular disease. It accelerates bone breakdown. It can weaken your immune system and increase your risk of infection. It can aggravate auto-immune diseases like rheumatoid arthritis.
And, of course, it just beats the hell out of your lungs. COPD can reduce your quality of life to nearly nothing. You wind up wheelchair-bound, dragging an oxygen tank around, and essentially leaving the house only to check into the hospital every few weeks for a severe exacerbation.”
