This guide provides key resources related to cannabis and its variants across multiple domains. The guide is still under construction to some extent, so expect to see changes and additions over time.
- Cannabidiol (CBD): a constituent of cannabis that has been traditionally considered non-psychoactive.
- Cannabinoids: one of a class of chemical compounds that act on cannabinoid receptors, cannabinoids can be naturally derived from the cannabis plant or manufactured.
- Cannabis: a broad term that can be used to describe the various products and chemical compounds derived from the Cannabis sativa or Cannabis indica species.
- Hemp: Cannabis plants with very low levels of THC (not more than 0.3 percent), also know as “industrial hemp”
- Marijuana: a Cannabis sativa plant-derived product typically composed from the plant’s dried leaves, stems, seeds, and buds.
- Tetrahydrocannabinol (THC): the main psychoactive constituent of cannabis.

The Health Effects of Cannabis and Cannabinoids: The Current State of Evidence and Recommendations for Research (2017)
In one of the most comprehensive studies of recent research on the health effects of recreational and therapeutic cannabis use, a new report from the National Academies of Sciences, Engineering, and Medicine offers a rigorous review of relevant scientific research published since 1999. This report summarizes the current state of evidence regarding what is known about the health impacts of cannabis and cannabis-derived products, including effects related to therapeutic uses of cannabis and potential health risks related to certain cancers, diseases, mental health disorders, and injuries. Areas in need of additional research and current barriers to conducting cannabis research are also covered in this comprehensive report.
