Key Concepts of Substance Abuse Disorders

Substance abuse disorders are significant contemporary health issues affecting individuals and communities. These disorders, ranging from alcohol and opioids to stimulants and gambling, lead to serious health risks and require comprehensive treatment strategies to address their complex nature.

1. Alcohol Use Disorder

   • Characterized by an inability to control drinking despite negative consequences.
   • Can lead to physical dependence, tolerance, and withdrawal symptoms.
   • Associated with various health issues, including liver disease, cardiovascular problems, and mental health disorders.

2. Opioid Use Disorder

   • Involves the misuse of prescription pain relievers, heroin, or synthetic opioids.

   • Can affect cognitive function, motivation, and mental health, particularly in adolescents.
