The effect of cannabis use on the time course of positive and negative affect in the daily life of youth.

| Study Type | Clinical Study |
| Population | Human participants |
This study addresses a critical gap in understanding how cannabis affects moment-to-moment emotional states in adolescents and young adults, moving beyond traditional laboratory settings to capture real-world usage patterns. Given the rapid increase in youth cannabis use and ongoing concerns about developmental impacts, understanding the acute emotional effects is essential for clinical decision-making.
This ecological momentary assessment study tracked cannabis use and emotional states in real-time among youth participants over multiple days. The research examined both positive and negative affect trajectories following cannabis consumption in naturalistic settings, providing insights into the temporal dynamics of mood changes. The study contributes to our understanding of cannabis’s acute emotional effects during a critical developmental period, though specific findings regarding effect magnitude and duration would inform clinical interpretation.
“While ecological momentary assessment provides valuable real-world data on cannabis and mood interactions, we still need more granular information about dosing, product types, and individual vulnerability factors to translate these findings into meaningful clinical guidance for young patients and families.”

FAQ
How did this study track cannabis use and mood in young people?
It used ecological momentary assessment, recording cannabis use and emotional states in real time among youth participants over multiple days. This approach captures real-world use in everyday settings rather than relying on traditional laboratory conditions. The study was published in Psychopharmacology.
What aspects of mood did the researchers examine after cannabis use?
The researchers examined how both positive and negative affect changed over time after cannabis consumption in everyday settings. The aim was to understand the time course of mood changes following use among adolescents and young adults, which the summary describes as a critical developmental period.
