Tobacco contains at least three substances that can cause problems: tar,
carbon monoxide and nicotine.
is a black sticky substance that settles on the flagella of the mucous
membrane, which goes from the nose to the lungs. This causes the flagella
not to remove dust and dirt very well anymore. Tar can lead to bronchitis,
pulmonary emphysema, lung cancer and cancer of the throat, oesophagus or
originates from the combustion of vegetable material. It is a
colourless and scentless gas. It causes the blood not to transport oxygen
as well anymore, which causes the heart and also other body parts to get
too little oxygen.
Carbon monoxide damages the walls of blood vessels so that fat and calcium
can settle more easily. Carbon monoxide leads to a reduced condition,
arteriosclerosis, heart complaints (Angina pectoris, heart infarct),
cerebral infarction and brain haemorrhage.
stimulates the nervous system, which brings up the heartbeat and
contracts the (small) blood vessels. This causes higher blood pressure.
Nicotine leads to addiction and hypertension.
