Title: The biological and neurological effects of cannabis use

Abstract

Cannabis is one of the most widely used psychoactive substances worldwide today and has become a significant public health issue due to its increasing use for both medical and recreational purposes. The primary psychoactive component in cannabis, Δ9-tetrahydrocannabinol (THC), causes effects such as euphoria, relaxation, perceptual changes, and impaired motor coordination in users through its effects on the central nervous system. The proliferation of products with increasingly higher THC concentrations in recent years has raised new concerns, such as the risk of addiction associated with cannabis use, cognitive impairment, and an increase in psychiatric problems.

Globally, cannabis use is creating a growing burden in the social, economic, and health spheres. Increasing consumption rates, the normalization of use among young adults, and legal regulations in some countries are creating additional challenges for public health. Individuals who develop use disorders often experience a decline in quality of life, losses in education and workforce participation, and deterioration in family and social relationships. Additionally, healthcare systems face an increasing burden due to cannabis-related acute intoxication, psychotic episodes, anxiety disorders, and addiction treatment processes.

Controlling cannabis use and reducing its harms requires a comprehensive understanding of the substance's pharmacological properties, neurobiological effects, and patterns of use. This presentation will address the pharmacological structure of cannabis, its effects on users, and the risks it poses to global public health. It is believed that the current scientific data will contribute to international academic studies focused on combating addiction and protecting public health.

This session presents a multi-layered framework ranging from the historical development of cannabis use to current epidemiological trends, and from its pharmacological effects to its neurobiological consequences. At the end of the presentation, participants are expected to:

•    Understand the historical development of cannabis use and current global trends,

•    Recognize the risks posed by products with high THC content,

•  Understand the effects of cannabis on the brain and the mechanisms of addiction,

•    Evaluate the psychiatric, cognitive, and social consequences of use,

•    Embrace the importance of evidence-based prevention and early intervention strategies.

In this context, the session is expected to contribute to both research and policy development processes by increasing scientific awareness regarding cannabis use.
