Cannabis use linked to higher morning cortisol

In late July 2026 researchers at Oregon State University reported that frequent cannabis users exhibit elevated baseline cortisol levels upon awakening compared with occasional or non‑users. The study measured saliva cortisol immediately after waking and again thirty minutes later over two workdays in 39 regular users and 43 controls. While the cortisol rise during the first half‑hour was similar across groups, the higher morning baseline suggests a dysregulated stress‑response system that could be a neurobiological marker of problematic cannabis use. The findings, published in the journal *Cannabis*, are cross‑sectional and do not establish causality, prompting calls for further longitudinal research. Media coverage in Croatia and North Macedonia highlighted growing international interest in the potential health implications of rising cannabis consumption.
