The chemistry and biochemistry of animal versus human reactions are widely varied and different from each other. This makes animal testing unreliable. “According to the United States General Accounting Office, 52 percent of new drugs marketed between 1976 and 1985 caused adverse reactions not predicted by animal studies.” Although these numbers have decreased in recent times, there is no doubt that the incidence of reactions occurring after product testing is still relatively high. Our society has used animal testing for centuries and is currently considered the “default method” for research, so it is understandable that finding new methods to test and research products is difficult, but it is entirely possible and should be done to stop the animal suffering and to ensure that the tests performed are useful and provide accurate results
