The topic cannabis may be too broad to be searched efficiently for a research paper. You might want to consider what aspect of a topic you want to research. The purpose of this LibGuide is to:
The box BU Library Database Links has links to the BU Library Catalogue and the Full List Of Databases to which BU subscribes. It then lists some of those latter databases that might be of particular interest.
Two other boxes - A sample of materials available through a BU Library Catalogue search....and Online Links - Examples - outline some possible resources for some of the aspects of this topic. The samples and examples include books, bills, news stories, organizations, statistics, theses, polls, government organizations, and government documents. This list is not exhaustive. It is not a replacement for a BU Library or BU Library database or other database search/es. Information changes, so it will not be the most up-to-date material. Content may be added or removed at any time. When you are searching for resources, be aware of the dates of your source material to ensure you are getting material from the time that you want.
If you are looking for laws and /or rules and/or regulations, consider the jurisdiction you want. Canada? Manitoba? Another province? A municipality? A city? Another country? Make sure you are gathering information that refers to the jurisdiction you need.
Sometimes it helps to use other terms in your search. Looking for some word alternatives? Try some of these.
