Increasingly potent concentrated cannabis products containing high levels of Δ9-tetrahydrocannabinol (THC) are being consumed with alcohol. This combination is known to acutely impair cognitive and psychomotor abilities, although few studies have evaluated alcohol and cannabis co-use using neural measures. This naturalistic feasibility study explored the acute effects of co-intoxication on...
Despite increased naturalistic psychedelic use in the United States, limited studies explore factors currently contributing to use among ethnically and racially diverse psychedelic and cannabis-using adults. This study employs thematic analysis using qualitative data to explore the factors contributing to contemporary psychedelic use. Qualitative interviews (conducted in 2022-2023) from a...
Theoretically, home practice of mindfulness is a critical mechanism underlying the benefits of mindfulness-based intervention (MBI), but rates of adherence to home practice recommendations are low for youth participants in MBI. In the current study, we test the extent to which the first supplement delivered via cellphone to an MBI increases rates of home practice, and to what extent home...
Greater mindfulness is thought to give rise to more positive psychological health through more adaptive emotion regulation. While there is extensive evidence linking higher average mindfulness to lower average emotion regulation difficulties, less is known about the momentary-level patterns that occur within individuals. Additionally, it is unclear if the relationship between mindfulness and...
High school youth have an elevated risk of substance use. Some substances (e.g., inhalants, MDMA) used by youth are overlooked or grouped in an "other" category. Compared to other racial/ethnic groups, American Indian (AI) youth may be at higher risk of using these substances. The purpose of this study is to examine the prevalence and patterns of use of "other" substances among youth living on...
OBJECTIVE: The goal of this study was to test if a mindfulness-based intervention (MBI) compared to an active control ameliorates the impacts of life stressors on momentary mindfulness and emotion regulation difficulties among adolescents exposed to chronic stressors. METHOD: Adolescents exposed to chronic stressors (N = 81, Mage = 13.75 years; 56% boys; 24% Hispanic/Latino, 57% White) were...
Psilocybin use in nonclinical settings is heterogeneous. We identified three profiles that differed on frequency and quantity of use and their associated demographic characteristics. Next steps are to identify factors that affect one's likelihood of experiencing particular use outcomes and to explore use variability.
There is a high need for accessible avenues for improving mental health among emerging adults, particularly on college campuses. Mindfulness-based intervention (MBI) is a promising avenue for reducing mental health symptoms, but initial discomforts associated with MBI may cause symptoms to fluctuate before decreasing, which presents a barrier to engagement with mindfulness on a daily basis....
Cannabis is commonly used among people who drink alcohol, yet evidence on acute effects of co-use is conflicting. Two important variables that may influence the effects of cannabis and alcohol are cannabinoid content (i.e., the ratio of cannabidiol [CBD] and 9-tetrahydrocannabinol [THC]) as well as the order of use (i.e., cannabis before alcohol vs. alcohol before cannabis). Research is mixed...
OBJECTIVE: Some American Indians legally use hallucinogenic substances as part of religious and spiritual ceremonies. Research to date has either failed to differentiate spiritual versus recreational use or has categorized hallucinogen use in an "other drug" or "illegal drug" category. This approach could contribute to ineffectual models of prevention and treatment intervention and limit...
