With the recent spate of state-based legislations authorizing medical cannabis use along with recreational cannabis use, physicians have been placed in the position of advising patients as to its use. With multiple agencies usually involved in the cannabis industry (e.g., Department of Public Health, Department of Agriculture, Drug Enforcement Agency, and Department of Financial and Professional Regulation among others), guidance and information for the primary care practitioner may be conflicting and difficult to obtain. This can be especially true in issues of cannabis and its adverse effects since the pharmacology of cannabis can be quite complex. Thus, cannabis-related medical issues and impairment may be somewhat challenging to predict and identify from the perspective of the primary care physician. This issue of Disease-a-Month by Dr. Donald E. Greydanus and his colleagues provide guidance on these very difficult clinic issues.
