What this record can show
This locally preserved record separates the registered protocol from source-reported registry results. Neither is a treatment recommendation.
Registry facts
Older adults are currently the fastest growing group of cannabis users in the U.S, and are more likely to use cannabis for medicinal purposes (e.g., pain, trouble sleeping, depression/anxiety) than for recreational purposes, despite having little data to guide their decisions about what type of product to use. This project utilizes a patient-centered observational design to recruit and assess older adults who are interested in using cannabis compared to a control group who is not interested in cannabis use. Investigators will gather data on both the beneficial and harmful effects of edible cannabis of varying composition (THC-only vs. CBD-only vs. THC+CBD), and will examine the process by which older adult cannabis users decide what type of cannabis product is preferred.
