Tobacco Smoking

Inhaling tobacco smoke into the lungs is one of the most perverse habits of humans. Cigarette smoking  leads to death from many types of cancer. In the USA  1 in 6 individuals in the United States smokes cigarettes despite years of warnings against the practice. Among high school students, the prevalence of cigarette smoking declined from 27.5% of students in 1991 to 9.2% in 2014. e-cigarette use has increased among youth in the past few years. The long-term health effects of this different form of nicotine delivery are largely unknown.

Tobacco smoke contains 4800 chemical compounds, including 69 carcinogens. And nicotine, the cause of addiction in smokers. Nitrosamines are the dominant carcinogens. Secondhand smoke comes with suspended particulates. The carbon particles get inhaled deep into the lungs and are especially harmful to small children whose lungs are just developing. Several chemicals are classified as Class A carcinogens. These include arsenic, asbestos, benzene, radon, and vinyl chloride. Secondhand smoke has also been classified as a Class A carcinogen. It, too, contains arsenic, benzene, and asbestos. It also includes formaldehyde and miscellaneous volatile organic compounds. Lung cancer is caused by tobacco smoking.

Chronic obstructive pulmonary disease (COPD) is estimated to affect 32 million persons in the United States and is the third leading cause of death. COPD is obstruction to air flow in the lungs that is not reversible.  Smokers develop COPD even after they quit smoking. Symptoms develop after age 40 in people who have smoked a pack a day for 10 years or more. The single most important preventive measure for COPD is not to smoke at any age in any amount. COPD also develops in family members of smokers and in people exposed to heavy doses of air pollution.

    Food Causes

    Not all respiratory diseases are caused by airborne pathogens. If asthma, bronchitis and/or nose sinus congestion is chronic or attacks occur frequently in all seasons and are not related to airborne exposure, then consider delayed pattern food allergy as the cause and do diet revision using the Alpha Nutrition Program.
