Smoking is an indisputable fact that it is harmful to health, but in the last century, this sentence caused great controversy.

In order to fight back the remarks that smoking is harmful to health, the British Tobacco Company conducted a test on 48 dogs . Within 3 years, these dogs took out an average of 5,100 cigarettes per day. What was the result? Let's take a look together.
starts the time
Tobacco was originally a native plant in the Americas and was used as a refreshing spirit by Indians .
Native Americans and Tobacco
European explorers found tobacco here, brought it back to their country and cultivated it.
Soon, people discovered that there is a substance in cigarettes that can make people addictive, but the degree is not as serious as drugs, and the harm is not that significant.
An idea popped up in the brains of smart businessmen, can this plant be used for business ?
About the 17th century, Europe began the tobacco trade, but tobacco was actually used to make cigarettes and commercialized in 1843.

French merchants made the first batch of commercial cigarettes in human history. Once sold, they became popular in the market and people wanted to try this novelty.
Many people suck for the first time, but they only feel energetic and the effect is similar to coffee.
Therefore, at the beginning, many people just used cigarettes as a tool to refresh themselves, but they became addicted over time.

As the market demand for tobacco increases, tobacco merchants have made a lot of money and continue to expand cigarette production.
problem also follows. Due to long-term smoking, various diseases have accumulated in the human body, so some people doubt whether cigarettes are harmful to the human body.
1920, scientist Auerbach responded to the needs of the people and studied the ingredients of cigarettes, and publicly stated that cigarettes have great harm to the human body .
As soon as these words were spoken, tobacco traders could no longer sit still. Such remarks undoubtedly harmed their interests. If public opinion fermented, tobacco industry is likely to fall into a cold winter.
Tobacco dealers have come up with a countermeasure, which is to use dogs to conduct public experiments so that everyone thinks smoking is harmless.
Of course, tobacco dealers are well aware of the dangers of smoking, so at the end, they replaced the dog of the experiment with a healthy living , and announced to the public that the three-year experiment was over, and there was no harm in smoking!
Dogs used for experiments
But the matter has not ended here. A righteous reporter exposed the relevant data of the experiment, which severely made tobacco dealers slapped in the face.
Inhumane experiment
The entire experimental process is carried out strictly in accordance with the process, after all, they occasionally have to accept external supervision.
Before the experiment started, a reporter named Mary sneaked into the experiment. She applied for the identity of the experimenter and successfully passed the test.
Mary's main job is to smoke cigarettes for her dog every day and be responsible for the dog's life and other work.
Before this, the relevant person in charge told her that everything that happened here must be kept confidential and promised that she would be given a generous bonus after everything was over.
On the first day of work, Mary came to the laboratory and saw about 48 dogs. They were each held in 48 sealed cages, with only their heads protruding, and special instruments were installed on their mouths.
As the experiment began, lit cigarettes were put into the sealed pipe, which connected the instruments of the dog's mouth, and the smoke entered the dog's lungs along the pipe.
The dog showed discomfort during the process and wanted to break free from the constraints of the device. However, was unable to break free from and could only be forcibly filled with smoke.
Many dogs fell into coma due to the irritating smoke, but the cruel person in charge seemed to not want to give them a chance to rest and instructed the staff to wake them up with electric current.
Each dog smokes about 100 cigarettes a day, and they cannot rest until they complete the task.
After a day, the dogs were tortured to the point of being in a mess. Two dogs were already dying .

Mary couldn't bear it, but in order to collect more evidence, she chose to persevere.
Fortunately, a few days later, the dogs all adapted to smoking and no longer had too much resistance.
A week has passed, and more than half of the dogs are skinny. They have no appetite after smoking cigarettes, and even the fragrant bones are placed in front of them, they are not moved.
Although Mary will take care of these dogs after work, their situation is not optimistic.
About half a year later, Mary quit her job and integrated evidence at home. During
, she collected the experimenter's abuse of dogs through various means and the most realistic impact of cigarettes on dogs.
When the cigarette company claimed that its experiment was successful, Mary published the evidence she collected in the newspaper.
As a reporter, she knew very well how to manipulate public opinion. Soon the people pointed the finger at the tobacco company, and members of the Animal Protection Association also stood up and protested the inhumane experiment.
Under the oppression of public opinion, the tobacco company revealed what happened.
It turns out that in less than a year, the dogs died of various diseases and the experiment was forced to end.
However, the tobacco company used money to connect the relationship between superiors and subordinates, which made everyone mistakenly think that the experiment was still going on. Three years later, they bought 48 new dogs to deal with the people.
In fact, the dog used for the experiment was very miserable. When the doctor dissected one of the dogs, he found that all the organs in its body had inexplicably shrank.
, especially the lungs, is like a piece of coke .
Healthy lungs and lungs that have been hurt by tobacco
It can be judged that the dog died of illness and his state was in his lifetime and he was in pain . The conclusion of
was extremely surprised by the public. People united and claimed to have to shut down the tobacco company.
In order to soothe the people's emotions, the British government has formulated a more stringent cigarette control law . As time goes by, people gradually forget this incident.
However, there was still a question at that time and has been heatedly discussed.
Should animals be used for live experiments?
The answer is yes. In order to promote the development of human science and technology, animal experiments are indispensable.
mice are regular customers of the laboratory
However, those inhumane living experiments must be explicitly prohibited, and even animals have their own power.
Therefore, during the experiment, we should try to avoid harming to animals and give certain compensation to those experimental subjects.
Back to the topic, since the experiment at that time brought such great harm to dogs, what kind of harm does smoking have to humans?
The harm of smoking
First, industrially produced cigarettes contain a large amount of carcinogens. Long-term smoking of cigarettes can easily induce cell lesions .
No matter how expensive it is, it contains more or less carcinogens.
Chemical substances in cigarettes
Common cancers caused by smoking include lung cancer, throat cancer, oral cancer , etc.
How harmful is cancer ? Naturally, there is no need to say much. For the sake of your health, you must refuse to smoke.
Second, it is the impact on the lungs. Various harmful substances in the smoke will accumulate in the lungs. If the amount accumulates too much, it will also affect other body organs such as the heart and intestines.
Third, Second-hand smoke is more harmful to others . Many smokers like to smoke at home, causing their relatives to suffer from adverse diseases.
Second-hand smoke has a greater impact on young children
Therefore, for the health of your loved ones, it is also recommended that you not smoke. If you really can't help it, you must go to an unmanned environment to avoid causing trouble to others.
Fourth, "old smokers"'s teeth are all yellow, which greatly affects personal image and can damage the structure of the teeth.
may not be obvious when young. Once the smoker reaches middle-aged and elderly, these teeth will soon fall off and even rot into .
Toothache is not a disease, it hurts so much. Refusing to smoke, start with you and me.
