What are some effects of smoking once?

Answer 1

There are 7,000 different chemicals in a cigarette - some of them known to cause cancer. Smoking just one cigarette results in inflammation within your blood vessels, which can lead to heart problems or stroke. 30% of strokes in people under age 65 are caused by smoking. Smoking also affects the lining of your nose and deadens your sense of smell. It affects the eyes and can cause macular degeneration. The smoke affects the way your lungs filter harmful elements from the air you're breathing. Smoking increases the acidity of the stomach, which can cause things like ulcers and increase the chance of getting Crohn's Disease. Carbon monoxide in the cigarette replaces some of the oxygen in your blood, making it hard for your body to get enough. Smoking can cause erectile problems in men and menstrual difficulties in women. Smokers tend to develop wrinkles sooner than non-smokers, too.
