Scopus claims to be "the largest abstract and citation database of peer-reviewed research literature in the fields of science, technology, medicine, social sciences and Arts & Humanities." So in theory, almost everything you find in this database should be from a refereed/peer reviewed source. Scopus does not provide a function to remove the admittedly small number of non-peer reviewed titles. Elsevier, the publisher, does provide a full title list (see at the bottom of the website: Looking for something else?), but this master list does not indicate whether a journal is refereed or not. If you want to double check you will need to locate the journal on a publishers website to see if the title self identifies as peer reviewed publication.
