Conference papers are an excellent source of current research, best practices and new innovations in a research area. For a start, search the Web using the name of the conference, meeting or symposium.
Full-text conference papers may be hard to obtain, sometimes abstracts are the only items available online. If a full paper is not available online, you could contact the author and request a copy. Also, the Library may be able to borrow or purchase published proceedings -- talk to the Pharmacology & Toxicology Subject Librarian.
