Female rats that inhaled vaporized cannabis daily for a month developed a blunted physiological response to stress, according to a new study by Washington State University researchers.
In contrast, male rats that were provided access to the same potency of cannabis over the same 30-day window did not experience any physiological changes in how they responded to a stressful situation.
The results of the study, published in the journal
Neurobiology of Stress, indicate there may be significant differences in how chronic cannabis use affects males and females.
The WSU scientists' work also establishes a direct, experimental relationship between chronic cannabis use and dampened stress reactivity.
