Cigarette smoking can also cause: cancer of the mouth and throat, lung, oesophagus, stomach, colon, rectum, liver, pancreas, voicebox (larynx), tranchea, bronchus, kidney, pelvis, urinary bladder, cervix and cause acute myeloid leukaemia.
Cigarette smoking releases over 5,000 chemicals and many of these are harmful. The chemicals enter the lungs and spread around the entire body and can damage your DNA and make it harder for cells to repair any DNA damage. They also damage the parts of DNA that protect us from cancer. The build-up of DNA damage in the same cell over time, leads to cancer.
How many cigarettes would you need to smoke to be harmful?
Even smoking less than one cigarette per day is harmful and increases the risk of getting smoke-related cancers and other diseases.
Both smoking and vaping involve heating a substance and inhaling the resulting fumes. With traditional cigarettes, you inhale smoke from burning tobacco. With vaping from a device (typically a vape pen or a mod – an enhanced vape pen – that may look like a flash drive) liquid heats up (called vape juice or e-liquid) until it turns into a vapour that you inhale.
What does vaping do?
Vaping coats the lungs with potentially harmful chemicals. The E-liquid concoctions usually include some mix of flavourings, aromatic additives and nicotine dissolved in an oily liquid base, giving it a more pleasant aroma.
How vaping can affect your lungs?
Several lung diseases are associated with vaping. Cancer is definitely a concern, given that vaping introduces a host of chemicals into the lungs. However, vaping products have not been around long enough for us to learn whether or not they cause cancer. We do know that smoking tobacco forces tiny particles to be deposited deep in the bronchial tree and can lead to the development of cancer. The same can be said to be true of vaping.
