The study, which was published in the journal, Cannabis and Cannabinoid Research, was conducted by graduate students from the Texas A&M University School of Public Health, as well as a colleague at the Hofstra University. They looked at data taken from the National Health and Nutrition Examination Survey from 2013 to 2018 taken by around 15,000 participants. Most of the participants were white females, over the age of 40, and at least had graduated from college.
