The raw material of cigarettes, tobacco, is a plant native to South America, as early as the primitive social stage of human beings have chewed tobacco, Indians are the earliest smokers. In the 15th century, when the European explorer Columbus discovered the "New World of america", he found that tobacco smoking was quite common in the Americas, and then tobacco was brought back to Europe and spread widely, gradually spreading across the world. The way people smoke tobacco goes from chewing tobacco, snuff, cigars, bucket cigarettes to later cigarettes.
At the end of the 19th century, paper cigarettes became the main form of tobacco use due to the rise of cigarette-making machines. After cigarettes were made, people did not know that this thing was harmful to health, coupled with the addictive nicotine ingredients, and advertising and marketing were done well, and in the 1950s, the number of smokers around the world increased significantly, and tobacco sales climbed steadily.
As the ranks of smokers grew, health organizations began to focus on the health problems posed by cigarette smoking. At that time, some scientists found that people who smoked had a particularly high number of cancers. In 1952, the American Cancer Society concluded through experiments and investigations that "smoking may cause cancer" to warn smokers that "smoking is harmful to health." This view caused smokers to panic, and for the sake of health, they had the idea of quitting smoking, and tobacco sales plummeted.
This has made the tobacco giant companies sit still, realizing that if they do not take measures, it may affect the survival of the tobacco industry. In response to the "smoking can cause cancer" rhetoric, British Tobacco "aggressively improved" tobacco and conducted a series of "smoking experiments" with a large number of hounds.
In the experiment, the experimenters asked the hounds to smoke 100 cigarettes a day to observe the changes that the lungs and body of the hounds might produce after the cigarettes entered the lungs of the hounds. Ultimately, the tobacco company claimed that the results of the trial showed that the hounds were still healthy after smoking tobacco, and showed that the hounds were still "alive and jumping" after smoking a large number of cigarettes. In this way, he proved that his improved cigarette products are not harmful to human health.
The results of animal cigarette experiments published by tobacco dealers and the results of scientists' studies are actually opposite, which has to make people suspicious of the results of tobacco manufacturers' experiments, but the experimental process of tobacco manufacturers is too confidential, and the specific details of the experiment are not known. However, the truth about the experiment was finally reported in 1975 by a female journalist named Mary Bass.
After the tobacconist announced the results of the test, journalist Mary Beth also sensed that something was wrong and suspected that the tobacco dealer had manipulated the animal experiment. So she disguised herself as a candidate and infiltrated the tobacco company to investigate. She started as a handyman, and after a positive effort, she finally got the opportunity to work in the laboratory. While participating in the experiment, she secretly filmed and recorded the cruel truths of the experiment that were not known:
Since animals do not actively smoke cigarettes, the experimenters will force the beagles to wear specific smoking masks, so that they are constantly forced to inhale a large amount of smoke. Even more cruelly, in order to achieve the experimental effect more quickly, forcing some experimental dogs to breathe concentrated cigarette smoke, 48 Beagles were forcibly cut through the throat and continuously delivered more smoke into their bodies through the instrument. These experimental dogs were forced to smoke for an average of 6 hours a day, with an average of no less than 100 cigarettes per day. What is even more tragic is that if there is an experimental dog that is comatose due to inhalation of excessive cigarette smoke during the experiment, the experimenter will use electric shock to wake it up and continue the experiment. It was such a cruel experiment that lasted for up to 3 years.
Experimental dogs naturally have difficulty supporting such an experiment of such intensity, and under the destruction of this experiment, most of the experimental dogs' bodies have been seriously damaged, and many of them have died continuously. However, in order to prove the "harmlessness of cigarettes", tobacco manufacturers always quietly dispose of the dead experimental dog carcasses cleanly, and at the same time constantly add new experimental dogs to cover up the truth, and finally show the healthy and lively experimental dogs to the general public, and issue fake experimental reports, indicating that smoking is harmless.
However, the tobacco companies' attempts to hide the sky did not succeed in the end thanks to the efforts of Mary Bass. She worked undercover in the laboratory for seven days, filming all this, and after leaving, she wrote her story into the article "The Beagles Smoking", which was finally released in 1975, exposing the cruel animal experiments of tobacco companies and the ugly behavior of deceiving consumers with false results.
As soon as this matter was exposed, it caused a huge sensation at the time, and people strongly condemned the inhumane animal experimentation of tobacco companies and launched protests. Many countries began to pay attention to the degree of harm of cigarettes, the "smoking harmful theory" began to be fully recognized, and the British authorities strictly prohibited tobacco companies from engaging in animal experiments.
When buying cigarettes, cigarette cases have the label "Smoking is harmful to health", but smokers seem to turn a blind eye to this, and they can't get rid of the attraction of cigarettes to them. While cigarettes bring pleasure to smokers, they also pose a multifaceted threat to the health of smokers. So, what harm does cigarettes cause to the human body?
Scientific evidence shows that tobacco smoke produced when smoking contains more than 7,000 known chemical components, including up to hundreds of harmful substances. Such as carbon monoxide, nitrogen oxides and other harmful gases and hydrogen cyanide and other volatile organic compounds; cadmium, lead, mercury and other heavy metals and radioactive substances; containing at least 69 kinds of carcinogens, including N-nitrosoamines, aromatic amines, thick cyclic aromatic hydrocarbons, heterocyclic 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 diseases, induce cardiovascular and cerebrovascular diseases, lead to atherosclerosis, reduce life expectancy, reduce sperm quality affect reproductive function, and may also cause osteoporosis.
Every year, around 5 million people die prematurely from tobacco worldwide. People who smoke have a 10-year lower average lifespan than non-smokers. On the mainland, there are more than 300 million smokers, and tobacco kills more than 1 million people on the mainland every year. Smoking not only endangers their own health, people around them smoke second-hand smoke is also very harmful, for their own and their families' health, it is recommended that everyone stay away from tobacco!
