About us
The Cannabis, Health, and Young Adults (CHAYA) Study was Initially funded in 2013 by the National Institute on Drug Abuse (NIDA) to examine the natural history of cannabis use among young adult users and how their cannabis practices evolved over time. This longitudinal study enabled us to document changes and stability in young cannabis users' substance use, health behaviors and health outcomes.

How safe is your weed? Patchy regulations may leave contaminants in the weed supply
The number of Americans who use marijuana has doubled over the past decade, according to a survey by Gallup. In many parts of the U.S., weed is legal under state law — and many Americans now use it as casually as they might have a beer or glass of wine. But finding cannabis products that are safely sourced and properly regulated can be tricky. In a new series, NPR is looking at what consumers should know about the safety of the weed supply.

A new roadmap for cannabis and
​cannabis policy research
Cannabis availability has greatly increased over the past two decades, leading to higher use and lower perceived harm, but research on its public health effects is lacking. A recent study suggests policies like limiting THC content and regulating marketing could protect public health. However, varying state laws and inconsistent data make it hard to draw firm conclusions. More research is needed on cannabis's health impacts, especially for vulnerable groups and new high-potency products. Improved surveillance and better impairment tests are also essential for guiding policy and protecting public health.
