In the News Article Identification Methods

Items posted to the In the News section of the website are manually screened and selected by members of the STEM project. News items are identified through two main pathways: 1) passive surveillance of news and academic sources by STEM team members, and 2) targeted biweekly Google News searches using predetermined search strings.[1] Potential articles are screened using the inclusion criteria in Table 1 and selected for posting every 2 weeks.

In the News is intended to provide selected information and context about the growing field of cannabis research and is not intended to be comprehensive. The items included do not reflect personal opinions or advocacy regarding cannabis and cannabis-related research.
