Background: Increased patient utilization of cannabidiol (CBD) leads to potential drug interactions with various medications and questions posed to pharmacists. Objective: To quantify the knowledge gap of pharmacists on CBD and CBD-containing products and assess the degree a continuing pharmacy education (CPE) program alters pharmacist confidence and competency on CBD knowledge. Methods: A 1-h CPE activity was offered as a home study from May 9, 2022, through September 30, 2022. Subjects were practicing pharmacy preceptors in Alabama who completed the pre-survey and post-survey for inclusion in matched-pair analyses. The primary outcome measure was participant score improvement between the pre-post surveys. Secondary measures involved pre-post comparisons on self-rated Likert questions concerning participant confidence in counseling, answering drug information questions, and ensuring patient safety regarding CBD. Results: A total of 124 participants completed the course. After matched pairing, 64 and 56 individuals were included in the knowledge-based and confidence ranking analyses, respectively. Participant scoring improved on the knowledge-based questions between the pre-post surveys (50.0% vs 87.8%, P < .001). There was a significant confidence improvement of participants from baseline on counseling patients about prescription or over-the-counter CBD products, answering questions from other healthcare professionals about these products, and ensuring patient safety while using these products (Average 5-level Likert scale increases of 1.75, 1.73, 1.70, respectively; all P < .001). Conclusion: Implementation of a CPE program improved practicing pharmacists' knowledge on information about CBD, which lead to increased competency on counseling patients, answering drug information questions, and promoting patient safety.
