Ethnic differences in the patterns, sources, and reasons for cannabis use among cancer patients at an NCI-Designated Cancer Center.

Objective: This study aims to describe patterns, sources, and reasons for cannabis use among cancer patients by ethnic group.

Methods: Data are from a cross-sectional study of 416 surveys collected via RedCap anonymously from adult cancer patients seen at a National Cancer Institute-designated comprehensive cancer center within the last 5 years. A harmonized survey was created with 11 other National Cancer Institute centers to assess cannabis use patterns, sources, and reasons for use.
