Smoking was established as a cause of lung cancer in the late 1950s. It then took another 50 years to establish that colorectal cancer was also a smoking-related cancer. However, as of 2018, a causal relationship between smoking and breast cancer had not yet been established. It may seem strange that it is taking so long to prove that smoking is a cause of all three of the most common cancers globally. Breast and lung cancer each account for 2.09 million cases annually and colorectal cancer for 1.8 million.

Lung cancer is one of the most common cancers worldwide, accounting for 2.09 million cases and 1.76 million deaths in 2018. Two of the most prolific cancer epidemiologists of our time — Sir Richard Doll and Sir Bradford Hill — identified smoking as the biggest cause of lung cancer in their seminal report, “Smoking and Carcinoma of the Lung”, published in the British Medical Journal in 1950. Nearly 70 years later, smoking remains the predominant risk factor for lung cancer, as well as for 15 additional cancers and other non-communicable diseases.

A new study shows that asthma is three times more common in those who had a father who smoked in adolescence, and twice as common in those whose father worked with welding before conception. Can these numbers be reduced by including adolescent boys in public health prevention programmes?
It is well known that a mother’s environment plays a key role in child health. The hypothesis that health and disease originate early in life has dramatically increased our understanding of this issue. However, recent research suggests that this may also be true for fathers; i.e. father’s lifestyle and age appear to be reflected in molecules that control gene function. There is growing evidence from animal studies for “epigenetic” inheritance, a mechanism whereby the father’s environment before conception could impact on the health of future generations.

Waterpipe, also known as shisha, goza, narghile, arghile and hookah, is a traditional method for smoking tobacco. While it originated in Turkey, India and Iran, its use has spread on a global level over the past decade to the point of being labelled a global epidemic.
There are a number of explanations for the global spread of waterpipe tobacco smoking. First, people use it as a way to socialize, as it is smoked in groups. Second, the production of sweetened and flavoured tobacco (Maassel), resulting in aromatic and smooth smoke, can make it more appealing than cigarette smoking. Another major reason is a common misconception that waterpipe tobacco smoking is not harmful, or is less harmful than smoking cigarettes.
