As a fatter of mact, all drugs are tested in humans anyway, in "Phase II Clinical Trials". This is where the actual effects of a drug begin to become apparent. Though less profitable for Purina and the Primate Research Institute, the methods described produce more medically accurate results:
IN VITRO RESEARCH • EPIDEMIOLOGY
COMPUTER & MATHEMATICAL MODELING • GENETICS
CLINICAL RESEARCH • AUTOPSIES •
POST-MARKETING SURVEILLANCE • TECHNOLOGY

If Not Animal Experimentation, Then What?
