A perspective from NIDA leaders identifies critical research gaps in cannabis science, including the effects of high-THC products, consequences of exposure during brain development, and how to leverage the endocannabinoid system for therapeutics.
Cannabis researchers, funding agencies, and policymakers
Cannabis use expanded across all US demographics except adolescents
What the researchers found
Despite decades of cannabis pharmacology research, major knowledge gaps remain in: (1) enduring consequences of cannabis exposure during critical brain development windows, (2) effects of large daily doses of high-THC cannabis, (3) therapeutic opportunities from endocannabinoid system manipulation, and (4) strategies to treat cannabis use disorder and cannabis toxicity.
Why it matters
Coming from the leadership of the US federal agency responsible for drug abuse research, this article sets the agenda for future cannabis science. The identified gaps have direct implications for funding priorities and policy decisions.
The numbers in context
Cannabis legalization has expanded use across all US demographics except adolescents. Multiple targets identified for endocannabinoid system manipulation. Research gaps span developmental neuroscience, high-dose effects, therapeutics, and treatment.
How the study worked
Perspective article from the Director and Deputy Director of the National Institute on Drug Abuse, highlighting research priorities and knowledge gaps in cannabis and cannabinoid signaling research.
What this study cannot tell us
This is a perspective piece, not a systematic review. Reflects the priorities and viewpoint of US federal drug research leadership, which may not fully represent all stakeholder perspectives.
How to read the evidence
Authoritative perspective from federal research leadership, carrying significant weight for research direction but not providing new data.
When this study was published
2024 perspective
The bigger picture
The tension between rapidly expanding cannabis legalization and incomplete scientific knowledge is the central challenge identified. The endocannabinoid system offers both therapeutic opportunities and vulnerability to cannabis-related harm.
Questions still open
- How will federal research priorities change if cannabis is rescheduled? Can the endocannabinoid system be targeted therapeutically without the risks of exogenous cannabis? What study designs can best address the developmental exposure question?
Common questions
What don't we know about cannabis?
Is cannabis research keeping up with legalization?
