Changes to This Summary (10/30/2013)
Editorial changes were made to this summary.
In writing Cancer Information Summaries, PDQ Editorial Boards review current evidence. They do not make recommendations or develop guidelines. Their work is editorially independent of the National Cancer Institute (NCI). This summary on Cannabis and cannabinoids does not represent a policy statement of NCI or NIH. The summary statement represents an independent review of the literature; that review is not influenced by NCI or any other federal agency.
