Forensic science has been a significant aspect of the criminal justice system for centuries. With the growing determination to develop forensic science over the years, advances have led to the development of many significant sciences, including toxicology. Understanding and studying the adverse effects of chemicals on biological systems has proven to be a necessary strength in the criminal justice system. Exploring new theories in toxicology, successes and failures throughout the historical progression of this science has led to leaps and bounds in crime investigations and a promise for a more competent future in toxicological studies. Forensic Science Since the beginning of history, forensic science has been thoroughly scrutinized. Developing an understanding of science and how it can apply to legal issues has been a necessary force in society and in the interest of the criminal justice field. Since the 1950s, the fascinating marriage of science and criminal justice has led to surprising developments in managing the age-old burden of crime. One of the major contributions to the successful advancement of forensic science is the establishment of the American Academy of Forensic Sciences in 1950. The goal of this organization was to bring together multidisciplinary professionals for the purpose of seeking the continued advancement of science for the benefit of the system legal (American Academy of Forensic Sciences, 2010). In doing so, this organization has promoted a unique focus on forensic science for the future of criminal justice. Another major contribution to the advancement of forensic science was the discovery of the Kidd blood classification system by F.H. Allen and colleagues in 1951.
