Cannabis Consumers Wake up with More ‘Stress Hormone’
Researchers found frequent cannabis users woke with higher cortisol levels, suggesting possible changes in daily stress rhythms, while the morning rise remained similar.
Researchers from Oregon State University discovered that frequent cannabis users wake up with higher levels of the "stress hormone" cortisol than nonusers, starting their day with elevated cortisol circulating through their bodies.
The cortisol awakening response measures the body's ability to prepare for daily stressors, peaking around 30 minutes after waking. Scientists focused on this metric to examine stress-response systems in cannabis users.
Almost 29% of adults aged 19 to 30 report cannabis use in the previous 30 days, a figure that has nearly doubled in 15 years. Over 10% of that age group use the drug 20 or more times monthly.
Study leader Anita Cservenka suggests frequent cannabis use may impair daily stress rhythms, potentially creating a "dysregulation" of the body's stress system that could lead individuals into a cycle of increased drug use.
Cservenka emphasized the study does not prove a direct cause-and-effect relationship, noting researchers would need to study the same groups over a longer period to understand if cannabis use drives these cortisol changes.
