Due to recent legalization of marijuana across many states, including Oregon, our lab’s current interests are to understand how marijuana use affects cognitive functioning. Since the human brain continues to mature into the third decade of life, individuals using marijuana during a critical period of brain development may be at higher risk for abuse and/or dependence. Our current study aims to determine marijuana’s effects on higher order executive functions.
The purpose of this study is to examine how marijuana use affects levels of the stress hormone, cortisol. It is currently unknown how marijuana use may affect cortisol functioning and daily levels of the hormone. Biological measures as well as self-report measures and tasks will be used to examine the relationship between marijuana use and cortisol levels in this study.
The purpose of this study is to investigate the effects of alcohol and marijuana use on emotional and social functioning in young adults. Task based measures to assess emotion recognition, as well as self-report questionnaires examining socio-emotional processing will be used to understand how alcohol and marijuana use and non-use affect emotional processing.
