Many cosmetic and medical products are tested on animals, but the treatment of animals and the quality of test results are often less satisfactory than the consumer expects . Everyone has most likely purchased a pharmaceutical or cosmetic product in their life, but the careless manufacturing techniques of these products can amaze people who rely on medications for their daily use. According to the Food and Drug Administration, "each year, approximately fifteen hundred" drugs are created, but "one thousand two hundred" are deemed unusable for humans. Regardless of such a high number of drug rejections, approximately “one million Americans are hospitalized due to drug defects” (“Animal Experimentation,” 2009). Most of these drugs were tested on animals before being approved for human use, proving that animal testing is not an effective method of experimentation. Certain factors must be considered when deciding which testing method is most useful to society; whether an animal has similar genetics to humans, whether the animals tested are treated humanely, and the costs of conducting the tests. Scientists and animal rights groups have argued for centuries about the morality of using experimental animals and about human safety when using animals for toxic experiments. People who perform animal testing usually claim that there is no alternative or that it is the safest method of all, but they may not be aware of modern technologies capable of producing new improved data for certain pharmaceutical products. other small animals are most often used as test subjects, but most animals lack certain human biological and emotional structures that are necessary for developing medical treatment and co...... middle of the paper......7065), 144146. doi:10.1038/438144aAnimal testing is necessary to ensure product safety.
