# Frequent Cannabis Users Woke with Higher Cortisol Levels in a New Study of Daily Stress Rhythms > **Author:** Benjamin Caplan, MD (ABFM Board Certified, MA Lic. #240562, NPI: 1962722637) > **Publisher:** CED Clinic (https://cedclinic.com) > **Canonical URL:** https://cedclinic.com/frequent-cannabis-users-woke-with-higher-cortisol-levels-in-a-new-study-of-daily-stress-rhythms/ > **Published:** 2026-08-11T12:24:06-04:00 | **Last Modified / Clinically Audited:** 2026-09-28T17:12:19-04:00 > **Clinical Summary:** Study links frequent cannabis use to elevated cortisol awakening response. Clinical implications for stress regulation and daily dosing counseling. --- ✦ New CED Clinical Relevance #67 Notable Clinical Interest Emerging findings or policy developments worth monitoring closely. Research[Mental Health](https://cedclinic.com/cannabis-psychiatric-research-findings-depression-anxiety/)THCSafetyAnxietySleepDosing Why This Matters Elevated morning cortisol in frequent cannabis users may indicate dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which could contribute to anxiety, sleep problems, and chronic stress-related conditions that patients report. Clinicians should assess cortisol patterns and stress responses when evaluating frequent cannabis users presenting with fatigue, mood changes, or sleep disturbances, as this endocrine effect may require targeted intervention. This finding highlights the need to counsel patients about potential physiological consequences of daily [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) beyond psychiatric or behavioral effects. Clinical Summary # Clinical Summary A recent study examining daily stress rhythms in frequent cannabis users found elevated cortisol levels upon waking compared to non-users, suggesting disruption of the normal hypothalamic-pituitary-adrenal (HPA) axis function. This dysregulated cortisol awakening response may have significant implications for stress resilience, immune function, and [metabolic health](https://cedclinic.com/cannabis-compounds-reverse-fatty-liver-disease/), particularly in patients using cannabis chronically or daily. The findings raise clinical concerns about whether frequent [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) may impair the body’s ability to mount appropriate physiological stress responses, potentially affecting treatment outcomes in patients with stress-related or inflammatory conditions. Clinicians should consider asking about [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) frequency when evaluating patients with fatigue, metabolic dysfunction, or poor stress tolerance, as chronic use may contribute to HPA axis dysregulation. For patients currently using cannabis daily or frequently, this research provides evidence-based rationale for discussing potential metabolic and endocrine consequences and considering dose reduction or cessation as part of comprehensive health optimization. Dr. Caplan’s Take “This observational study raises an interesting signal about cannabis use and cortisol awakening response that warrants attention, but we need to be careful about causality here – we don’t know if cannabis is elevating morning cortisol, or whether people with dysregulated stress responses are self-selecting to use cannabis more frequently. What I tell patients is that the relationship between cannabinoids and the HPA axis is complex and individual, and this kind of finding is exactly why we need more controlled research before making broad clinical recommendations.” Clinical Perspective 💤 Elevated morning cortisol in frequent cannabis users warrants clinical attention, though the mechanistic relationship between cannabis use and hypothalamic-pituitary-adrenal axis dysfunction remains incompletely understood and may reflect reverse causality (individuals with baseline stress dysregulation self-selecting into cannabis use). The cross-sectional nature of this finding limits causal inference, and individual variation in cannabis potency, frequency, [route of administration](https://cedclinic.com/state-ban-smokable-cannabis-impact-central-texas/), and duration of use could substantially influence cortisol patterns in ways not yet characterized. Given that dysregulated cortisol awakening response is independently associated with depression, anxiety, and poor health outcomes, clinicians should ask about cannabis use frequency when evaluating patients with mood or sleep complaints, while recognizing that cannabis may be used as self-medication for underlying stress or trauma. The practical implication is that regular cannabis users presenting with fatigue, anxiety, or poor stress tolerance might benefit from targeted assessment of HPA 💬 Join the Conversation Have a question about how this applies to your situation?
