The science of toxicology usually involves the study of poison, venom, acids, and other harmful substances. Students may be able to learn general biological and chemical principles while discovering how exposure to toxins can be prevented and treated.

Master-level studies involve specialized study in a field of research or an area of professional practice. Earning a master’s degree demonstrates a higher mastery of the subject. Earning a master’s degree can take anywhere from a year to three or four years. Before you can graduate, you usually must write and defend a thesis, a long paper that is the culmination of your specialized research.
