Now everyone knows that smoking is harmful to health, especially in the cigarette box also has the slogan "Smoking is harmful to health", but even if everyone knows the harm of smoking, it is still impossible to resist its temptation, and even some people have become a habit of smoking.
However, when British Tobacco Company sold cigarettes, it declared that smoking was not harmful, let people buy cigarettes in a big way, and used 48 dogs to do an experiment to prove that smoking is not harmful, so is smoking harmful? What are the specific hazards? Let's take a look at The British Tobacco experiment.
Tobacco experiments on 48 beagles.
Legend has it that the Indians stumbled upon a plant that produced an addictive odor after burning, which was first discovered as tobacco, and later the plant was frequently burned and used and made into cigarettes, which became popular for a while.
But the good times did not last long, after 1920, some researchers found that long-term smokers are prone to disease, many people began to buy less tobacco, and some British tobacco companies in order to reduce the decline in sales, make greater profits, with beagles to do experiments to prove that smoking does not affect the human body Is this:
British tobacco manufacturers first purchased 48 beagles, and each dog was equipped with a smoking device, and the amount of smoking devices was 100 cigarettes a day, and at the end of the experiment, the beagles did not seem to have a significant change, so the results of the experiment that smoking was harmless, so the public began to buy tobacco unscrupulously.
Is smoking really harmless? At that time, a reporter questioned this, and took action to enter the tobacco dealer's laboratory, found that the 48 beagles were locked in a confined space and forced to "smoke" every day, and also cut open the trachea of some dogs directly into the smoke, and the dogs who fainted due to excessive smoking would be awakened by electricity and then smoked, the whole scene was very cruel, and then she published the matter in the newspaper, and people really realized that smoking was harmful to health.
