Trending: Social media analysis to monitor cannabis and synthetic cannabinoid use

edrug trends logoSubmitted in response to NIDA RFA-CA-14-008, this multi-PI study builds on interdisciplinary collaboration between the researchers in the Center for Interventions, Treatment, and Addictions Research and the Ohio Center of Excellence in Knowledge-enabled Computing (http://knoesis.org/) at Wright State University. The main goal is to develop an innovative software platform, eDrugTrends, that will facilitate analysis of trends in knowledge, attitudes, and behaviors related to the use of cannabis and synthetic cannabinoids as discussed on Web forums and Twitter. We will build on the existing infrastructure developed by our interdisciplinary research team: Twitris, a robust and highly scalable platform designed to analyze Twitter data, and PREDOSE, a platform developed for our collaborative NIH grant (R21 DA030571) to analyze Web forum data on illicit buprenorphine use. Key elements of Twitris and PREDOSE will be adapted and enhanced using Semantic Web, Natural Language Processing, and Machine Learning techniques to advance the analysis of social media data for drug abuse research.

The Specific Aims are to:

  1. Develop a comprehensive software platform, eDrugTrends, for semi-automated processing and visualization of thematic, sentiment, spatio-temporal, and social network dimensions of social media data (Twitter and Web forums) on cannabis and synthetic cannabinoid use.
  2. Deploy eDrugTrends to:
    1. Identify and compare trends in knowledge, attitudes, and behaviors related to cannabis and synthetic cannabinoid use across U.S. regions with different cannabis legalization policies using Twitter and Web forum data.
    2. Analyze social network characteristics and identify key influencers (opinions leaders) in cannabis and synthetic cannabinoid-related discussions on Twitter.

Cannabis remains one of the most commonly used psychoactive substances in the U.S., and current changes in legalization policies indicate broadening acceptability. At the same time, substance abusers have sought similar, or more enhanced highs, through use of synthetic cannabinoids, new designer drugs with constantly changing chemical formulations that have been linked to adverse health effects. The development of eDrugTrends will advance the field’s technological and methodological capabilities, and our deployment of the platform will inform the field on new trends regarding the use of cannabis, synthetic cannabinoids and other drugs.

This study is funded by the NIH/NIDA Grant No. R01 DA039454-01.
