It is currently unknown how marijuana use may affect cortisol functioning and daily levels of the hormone.

Marijuana and Cognitive Functioning in Young Adult College Students Study


Due to legalization of recreational cannabis across many states, including Oregon, our lab’s current interests are to understand how cannabis use affects cognitive functioning. Since the human brain continues to mature into the third decade of life, individuals using cannabis during a critical period of brain development may be at higher risk for cannabis use disorder. This study aims to determine the effects of cannabis on higher order executive functions.
