Cannabis use represents a major public health issue throughout the globe. Yet, we still lack the most fundamental of knowledge on long-term effects of cannabis on neural, cognitive, and behavioral function. Part of this stems from how cannabis has been measured. To this end, most empirical examinations of cannabis have historically consolidated all types of cannabis collectively. However, this approach misses a fundamental fact about how different cannabinoids operate. Here we address the contrasting properties of tetrahydrocannabinol (THC) and cannabidiol (CBD) and their opposing effects on a wide array of health function. In addition, we address the increase in cannabis potency throughout the past two decades and how that impacts generalizability of early data on current public health. We put forth the urgent need for future research to disaggregate examination of THC from CBD, along with the importance of measuring potency of cannabis to more effectively unravel its impact on health related issues.
