A team at Oregon State University has found that people who use cannabis frequently begin each morning with measurably higher levels of cortisol — the body's primary stress hormone — than those who do not. The finding does not yet tell us whether cannabis disrupts the stress system or whether a disrupted stress system draws people toward cannabis, but it surfaces a question of growing consequence: as routine cannabis use doubles among young adults, what quiet negotiations are taking place between the substance and the body's deepest regulatory rhythms? Science, for now, holds the thread withou

Economic Lens
📈
Study links frequent cannabis use to elevated morning cortisol levels, suggesting potential stress-response dysregulation. With 29% of US adults aged 19-30 using cannabis monthly, this has health and economic implications for workforce productivity and healthcare costs.

Workplace productivity
Frequent cannabis users may face increased healthcare costs from stress-related conditions (anxiety, depression, cardiovascular issues). Elevated cortisol could reduce workplace productivity and cognitive function. Consumers may shift toward alternative stress-management products or therapeutic services.
Potential regulatory scrutiny of cannabis marketing claims regarding stress relief. Occupational health policies may require cortisol screening for safety-sensitive positions. Public health campaigns could emerge targeting young adults. Insurance companies may adjust premiums or coverage. Workplace drug testing policies may be re-evaluated. Further research funding may be directed toward cannabis health effects.
