To the lab. Animal ,hell on earth. To people, much misery because of side effects of drugs passed as safe by lab tests ( a cover for the mega rich drug companies) . In the you K the NHS spends £466 MILLION pounds EVERY YEAR on patients who have side effects from animal tested so called safe drugs. The biggest disadvantage is the total acceptance of diseases such as cancer being inevitable and the drive for a cure. When we should all be looking for the causes and stopping it from occuring but the fixation is on using ALL DIFFERENT types of species all classified under the heading of animals for experimentation where those outside of the scientific world are disadvantaged and those humans on the inside are the only ones that gain big time.
