Scientific evidence of health risks created by smoking was proven way back in the 1950s. Statistics from the US government show that 23% women of 18 years old and above and 28% men of the same age group were into the addiction in the mid 1990s. The proportions were still higher as at 1964, when the US surgeon general first hand out an official caution that smoking was unsafe to one's health.
Following that formal warning, many reports were released on the link between cigarettes and tobacco to heart diseases, lung diseases, and cancers of the mouth and other tissues. Nevertheless, the practice persevered, with fresh smokers doing so as an appearance of revolt and strong drive to be free.

For adults, smoking marked an addiction to nicotine – the key reason that made smoking a pleasurable and addictive experience. This led to another warning from the surgeon general in 1988, which put addiction to nicotine on the same level as cocaine and heroin.
The menace in smoking originate from the chemical substances on the loose either as a gas or as a particulate. Hydrogen cyanide, nitrogen oxide and most particularly carbon monoxide are gaseous releases from cigarette smoke that terrorize to poison the body.
Nicotine is one of the many harmful particulates send out from smoking. The cilia are damage by these particulates -the little hairs lining the lungs that aid in carry mucus out of the lungs, and all pollutants amassed. When the cilia malfunction, pollutants stay in the lungs and the likelihood of influenza and bronchitis, emphysema and other diseases increases.
The likelihood that smokers die from heart disease and cancer is twice that of their non-smoking counterparts. Individuals who smoke also have lungs that become less efficient with age faster than those who don't. Smoking has been mentioned as the reason of over 400,000 deaths in the US every year.
Government agencies, scientists and health officials have also established that passive smoking, or second-hand smoke, also has ill effects. The National Center for Chronic Disease Prevention and Health Promotion has reported that over 4,000 chemicals are generated by second-hand smoke, with more than 50 of those believed to be cancer-causing agents.
In 1975, the Centers for Disease Control released a report citing such a danger, noting that toxic chemicals stay in the air and are inhaled by innocent victims. Thus, the worry over smoking as a private choice by people expanded into a public-health issue.
Passive smoking was mentioned as a cancer-causing agent by the US Environmental Protection agency in 1993. For pregnant women, smoking raises the chance that their baby will be underweight or that they end up with a miscarriage. Children less than a year old are twice as likely to have lung infections if their mothers smoke compared to counterparts whose mothers do not practice the habit. Individuals with asthma, allergies or other respiratory ailments were also advised, as exposure can worsen their conditions.
Some smokers gradually quit or smoked less, while nonsmoker became the focus of more protection, as government worked on policies and legislation to curb the habit. As early as 1964, the US signed into law a need that health warnings must be integrated into all cigarette advertising and packaging. Policies were also implemented to appointed schools, offices and other public places as smoke-free buildings.
In the 1990s, class action suits started to bombard state and federal courts, claiming that cigarette makers employed deceptive marketing strategies to keep consumers from knowing that nicotine was addictive and worked on levels of the particulate in cigarettes to keep smokers hooked on their product.
More recent suits against the industry charge manufacturers of also misleading consumers into thinking that “lights” and similar products were healthier alternatives to regular cigarettes. These more recent cases later led to the multi-billion dollar settlement between the US government and industry in the late 1990s.
These lawsuits and the consistency of health lobbyists and persuasive government programs have helped draw down US smoking rates on a constant basis over the last four decades, with government figures showing per capita rates at 22.5% and experts forecasting the rates to continue declining in the future.
