48 dogs smoked 100 cigarettes a day to prove that smoking is harmless

Tobacco, the raw material of cigarettes, is a plant native to South America, as early as in the primitive stage of human society there is the behavior of chewing tobacco, Indians are the earliest smokers. 15-century European explorer Columbus in the discovery of the "New World of America", found that smoking tobacco in the Americas has been quite common. found that smoking tobacco in the Americas has been quite common, then tobacco was brought back to Europe, and was widely spread, and gradually spread around the world. The way people smoke tobacco, experienced from chewing tobacco, snuff, cigars, and pipe tobacco to the later cigarette.

At the end of the 19th century, due to the rise of cigarette manufacturing machines, paper cigarettes became the main form of tobacco use. After cigarettes were manufactured, people did not know that smoking the stuff was bad for their health, and with the addictive nicotine content and good advertising and marketing, the number of people smoking worldwide increased dramatically in the 1950s, and tobacco sales were on the rise.

As the ranks of smokers continued to grow, health organizations became concerned about the health problems associated with cigarette smoking. In 1952, the American Cancer Society, after experiments and research, concluded that smoking could cause cancer, thus warning smokers that smoking was bad for their health. This view put smokers into a panic, for the sake of health have the idea of quitting, and tobacco sales have declined sharply.

This made the tobacco giant companies sit up and realize that if they do not take measures, it may affect the survival of the tobacco industry. To counter the "smoking may cause cancer" speech, the British tobacco companies "actively improve" the tobacco, and take a large number of hounds to conduct a series of "smoking experiments.

In the experiment, the experimenters let the hounds smoke 100 cigarettes a day, to observe the cigarette in the hounds' lungs, the lungs, and the body may produce changes. Ultimately, the tobacco company claimed that the test results show that these hounds smoked tobacco, were still healthy, and showed a large number of cigarettes still "alive and well" after the hounds. To confirm that their own improved cigarette products are healthy and harmless to humans.

Tobacco companies announced the results of experiments on animal cigarettes and scientists' findings are surprisingly opposing, and people have to be suspicious of the results of tobacco companies' experiments, but the process of tobacco companies' experiments is too confidential, there is no way to know about the specific details of the experiments. However, the truth about the experiment was finally reported in 1975 by a female journalist named Mary Beth at the time.

After the tobacco companies announced the results of the experiment, the reporter Mary Beth also noticed that the matter is not right, and suspected that the tobacco companies in the animal experiments tampering. So she disguised herself as a job applicant and infiltrated the tobacco company to investigate. She started as a handyman, and after a positive performance, she finally got the opportunity to work in the laboratory. She secretly photographed and recorded the brutal truths of the experiments she was involved in, which were not known to anyone.

Since animals do not actively smoke cigarettes, the experimenter will force the experimental Beagle to wear a specific smoking mask, so that they are constantly forced to inhale large amounts of smoke. Even crueler, to achieve the experimental effect more quickly, forcing some dogs to breathe concentrated cigarette smoke, 48 Beagles were forced to slit their throats, and more smoke was continuously delivered to their bodies through the apparatus. The dogs were forced to smoke for an average of 6 hours per day and smoked an average of no less than 100 cigarettes per day. What was even more tragic was that if a dog passed out from inhaling too much cigarette smoke during the experiment, the experimenter would use electric shocks to wake it up and then continue the experiment. This cruel experiment lasted for 3 years.

The experimental dogs naturally could not support the intensity of the experiment, in the experiment, the destruction of the body of most of the experimental dogs was severely damaged, and a lot of constant death. But tobacco companies to prove the "harmless theory of cigarettes", always quietly dispose of the bodies of dead lab dogs clean, while new lab dogs will continue to add in, to cover up the truth, and finally show the general public healthy and lively lab dogs, the release of fake experimental reports, that smoking is not harmful.

However, this attempt by tobacco companies to hide the truth from the public did not ultimately succeed in the efforts of Mary Beth. She worked undercover in a laboratory for seven days, during which time she filmed it all, and after she left she wrote a paper on her experiences, "The Smoking Beagles," which was eventually released in 1975, exposing the tobacco companies' cruel animal experiments and their scandalous behavior of deceiving the general public with false results.

Once the story was exposed, it caused a huge stir at the time, and people strongly condemned the inhumane animal experiments of tobacco companies and launched a protest campaign. Many countries began to pay attention to the extent of the harm of cigarettes, "smoking is harmful to the theory" began to be fully recognized, and the British authorities strictly prohibit tobacco companies to engage in animal experiments.

When buying cigarettes, there are signs on the boxes that say "smoking is harmful to health", but smokers seem to ignore this, they can not get rid of the appeal of cigarettes to them. While cigarettes give smokers pleasure, they also pose a threat to their health in many ways. So, what harm can cigarettes do to the human body?

Scientific research evidence shows that the tobacco smoke produced when smoking contains more than 7,000 known chemical components, which contain up to hundreds of harmful substances. Such as carbon monoxide, nitrogen oxides, and other harmful gases, as well as hydrogen cyanide and other volatile organic compounds; cadmium, lead, mercury, and other heavy metals and radioactive substances; contains at least 69 types of carcinogens, including N-minestrone, aromatic amines, thick-ringed aromatic hydrocarbons, heterosexuality amines, formaldehyde and so on. In addition to increasing the risk of cancer, long-term smoking is also closely related to a variety of diseases, which may lead to lung disease, induce cardiovascular disease, lead to atherosclerosis, reduce life expectancy, reduce sperm quality and affect fertility, may also cause osteoporosis, in short, smoking is harmful but not beneficial.

Every year, about 5 million people worldwide die prematurely because of tobacco. The average life expectancy of smokers is 10 years less than that of non-smokers. In China, more than 300 million smokers, and tobacco causes more than 1 million people to lose their lives every year. And smoking is not only harmful to their health, but people around second-hand smoke is also very harmful, to their health and the health of their families, we recommend that we stay away from tobacco!
