Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. All over the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk.
However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. Whilst a myriad of studies have examined cannabis use in all its quite a lot of forms, steadily these research conclusions don’t seem to be as it should be synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for protected use or appropriate dose are to be had to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively.
Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits may also be attributed to the usage of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€”outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€”that summarizes and prioritizes pressing research needs.
