Researchers discovered that 92 percent of drugs tested on animals do not make it through phase one of trials on humans. No matter how many tests animals undergo, because of how unreliable animal testing is, it makes human trials even more risky ("Animal Testing Is Bad Science."). The diseases and infections forced into animals do not replicate naturally occurring illnesses. Researchers should focus more on preventing diseases before they occur ("Medical Testing on Animals Is Cruel and Unnecessary."). Some of the artificial diseases injected in the animals are ones that would not commonly infect humans, which is wasteful in time, supplies, the lives of many animals. “Physiological reactions to drugs vary enormously from species to species. Penicillin kills guinea pigs but is inactive in rabbits; Aspirin kills cats and causes birth defects in rats, mice, guinea pigs, dogs, and monkeys; and morphine, a depressant in humans, stimulates goats, cats, and horses” ("Animal Testing Is Bad Science."). Even the best scientist cannot make this science
