How tobacco use contributes to cardiovascular disease, cancer, and chronic obstructive lung disease

How Tobacco Contributes to Cardiovascular Diseases

The report provided by the US surgeon indicates that tobacco usage has adversarial effects on the American health and financial costs to the nation (General 4). Moreover, a continuous use of this substance leads to increased addiction, death, and devastation of victim’s families. The report further states that tobacco causes approximately 33% of cardiovascular (CDV) deaths across the U.S. while ischemic heart mortality accounts for 20% among the aged population (86). Consequently, the paper provides details on how tobacco contributes to these illnesses, in particular through inhaling of harmful chemicals by the victims.

How Tobacco Causes Cardiovascular Deaths

The evidence portrayed in the general report show that increase in tobacco consumptions contribute to aspects such as glucose intolerance, low serum levels, and increased cholesterol in the blood (51). These elements lead in the formation fatty build-ups in the arteries and veins, a process that blocks the flow of blood and other materials to the body organelles. Consequently, the body’s physiological processes are negatively affected, thus, leading to the occurrence of cardiovascular death in the long-term usage (Jha, Prabhat, and Richard Peto 62).

How Tobacco Causes Cancer

Considerably, smoking tobacco contributes to the destruction of the deoxyribonucleic acid (DNA) that determines the transfer of genes within the body. Additionally, the inhaled chemicals damage other pathways in the mouth and throat. For instance, poisonous substances such as benzo (a) pyrene stick on this genetic material, thus, creating weak immunity for the body. Likewise, other chemicals such as nitrosamines reduce the ability of the body to destroy toxins thereby resulting in the formation of cancerous cells in the body (Ferkol, Thomas, and Dean 405).

How Tobacco Causes Chronic Obstructive Lung Diseases 

Tobacco materials contain carcinogens that destroy the cells that control the biological functions of the lungs. The repeated damages caused by these elements prevent the ability of the body to self-repair, a factor that leads to lung cancer due to the abnormal growth of the organelles (General 72).
