The study isn't establishing a direct link between cannabis and anxiety, it's looking very specifically at anxiety diagnoses following an ER visit. The findings are interpreted in the study as the following: "ED visits for cannabis use were associated with an increased risk of having an incident healthcare visit for an anxiety disorder, particularly in young males."
What exactly that means on the broader context of cannabis use isn't the focus of the study, but it invites further research to explore the implications of their findings.
