Chronic Cannabis Use Impacts Mood and Anxiety Levels in Young Adults Compared to Nonconsumers: A Literature Review

Abstract

The rising prevalence of cannabis use among young adults, fueled by legalization and changing social attitudes, raises concerns about its impact on mood and anxiety levels. This article explores the relationship between regular cannabis consumption and mental health outcomes, focusing on individuals aged 15 to 25. We examine the neurodevelopmental changes occurring during young adulthood, highlighting the potential risks associated with cannabis use, particularly in relation to the endocannabinoid system. Direct effects of cannabis, including heightened symptoms of anxiety and depression among heavy users, are discussed alongside the implications of tolerance and the seemingly contrasting effects of THC and CBD. Indirect effects, such as neurocognitive deficits and the influence of socio-economic factors, are also considered. The review emphasizes the need for a nuanced understanding of how both individual and environmental factors contribute to the varying impacts of cannabis on mental health. Ultimately, while regular cannabis use may exacerbate mood and anxiety disturbances in some individuals, others may experience reduced anxiety over time. Future research should focus on the interplay of these factors to inform public health initiatives and mental health interventions for young adults.
