Most people are fully aware of the dangers of smoking and the damage it can do to their health.
A teacher at Yan Chai Hospital Tung Chi Ying Memorial School in Hong Kong, Ryan Au, was so concerned when his students started to smoke, he decided to do a demonstration of the effects of cigarette smoking on a set of lungs from a pig.
The demonstration commenced with two sets of healthy lungs. One of the lungs is then inflated using clean air, whilst smoke equivalent to 60 cigarettes is used in the other. After this experiment, Ryan Au, cut the trachea of both lungs to reveal one perfectly pink lung and one black, charred lung.
Smoking would normally affect the colour of the lungs, but the shocking part of this experiment was how quickly this occurred. It only took 60 cigarettes for this to happen and there are many chain smokers who smoke at least one pack of 20 cigarettes each day. This means that over a period of three days, this may be effect on a person’s lungs.
Action On Smoking & Health have stated that there have been in excess of one billion tobacco-related deaths globally and the number is set to increase to 1.6 billion over the next 20 years.
Despite the numerous efforts by several public health organisations warning people of the negative effects of smoking, the habit is still growing.
