Cannabis and the endocannabinoid system (ESC) are rarely included in training programs for healthcare providers. Knowledge within the medical and dental health professionals is lacking regarding the treatment of patients using medical or recreational cannabis. Patients are unaware of the risks associated with cannabis use, and healthcare providers should be prepared to assess, educate, and treat the patients who use cannabis. With the increased legalization and use of cannabis for medical and recreational purposes across the US, this study demonstrated the lack of cannabis education provided in dental hygiene programs. In 2021, an online survey was conducted with 327 dental hygiene program directors. Respondents were asked to answer 26 questions. With a 21% response rate and 100% completion rate, 60% of the participants responded that cannabis content was provided in their dental hygiene program, 38% responded with a "no," and one responded with "I do not know." No significant difference was found regardless of whether cannabis was legal in the state for medical or recreational use and whether the cannabis content was included in the dental hygiene curriculum. The results indicate that every dental hygiene program should provide cannabis content, and each patient should receive a cannabis assessment at every dental hygiene appointment. Further research is required to identify standardized educational content on cannabis and the ESC, which will enable educators to teach students. The development and implementation of a standardized cannabis use assessment and the creation of standardized recommendations for patients who use cannabis to alleviate adverse oral health effects are important.
