Because it is all or nothing.
This is a copy & paste from an article that I read that triggered me into quitting the smokes…
There is no safe level of smoking. Even one cigarette a day is doing you harm. There have been scientific reviews of research into smoking-related illness in light smokers.
Light smoking increases the risk of lung cancer five-fold versus non-smokers, and also increases the risk of cancer of the oesophagus, stomach and pancreas. Any smoking increases the risk of cardiovascular disease. Dementia risk is also increased in all smokers. An awareness of health and lifestyle has led many to avoid additives and chemicals in food, skincare etc. The irony is that many of those who like to be “healthy” and avoid additives in their foods are ingesting far more dangerous toxins through their cigarettes. Ammonia, methane, methanol, toluene, cadmium and stearic acid are just a few of the toxins that make it into the average cigarette.
Smoking is associated with disease in virtually every organ system. Contrary to popular myth, smoking increases stress levels.
Smokers also age faster than non-smokers. The cosmetic changes referred to as “smoker’s face” can leave someone looking on average 10 years older than their non-smoking counterparts. Changes include early crow’s feet around the eyes, deep wrinkles on the lip line, sunken hollow cheeks, thinner skin (due to lower levels of collagen production), superficial broken veins, ruddy cheeks and yellow teeth. Cosmetic surgery isn’t always the answer as the risk of complication is higher in smokers and scars heal more slowly.
Quitting is the best thing any smoker can do for their health. The benefits are real. Within 20 minutes your heart rate and blood pressure start to fall. Within 24 hours, nicotine is eliminated from your blood. Two weeks later circulation improves and at a year, coronary heart disease risk is halved. Stroke risk is halved in five years and by 15 years the risk of cardiovascular disease and smoking-related cancer is reduced to that of a non-smoker.
Anyway, soapbox over, back to the weightloss.
