US scientists find frequent cannabis users wake with higher cortisol levels

Frequent cannabis consumers may experience elevated stress hormone levels upon waking, according to new research from the United States. Scientists in Oregon conducted a study to compare the daily patterns of cortisol, a key stress hormone, in individuals who regularly use cannabis versus those who do not.

The findings indicated a notable difference in the participants' cortisol levels, particularly in the morning. The study focused on the diurnal rhythm, or the natural daily fluctuation, of this hormone, suggesting that chronic cannabis use could impact the body's natural stress response system from the moment of waking.

While the study highlights a correlation between frequent cannabis use and higher morning cortisol levels, further research is likely needed to fully understand the implications of these findings. The researchers' comparison aimed to shed light on how cannabis consumption might influence the body's physiological responses throughout the day, starting with the crucial morning hours.
