Researching Medically Important Effects of Cannabis

Background and Purpose of the Study

Cannabis is used both recreationally and for its expected medical benefits such as pain relief. Attitudes towards cannabis use have rapidly evolved, and a majority of U.S. states have now voted to legalize cannabis use in varying contexts and forms. Understanding biological factors that contribute to cannabis use and its medically important effects is needed to guide effective and safe decisions about use.

We are conducting a novel, online-only research study to examine how human genetic variation and other factors influence the medical risks and benefits of cannabis use.

To be eligible for the study, you must be:

  • At least 18 years old
  • A 23andMe®  customer or an Ancestry.com customer who has had DNA testing

Our study is supported by the National Institutes of Health (NIH)
