## Health and Psychological Consequences of Substance Abuse
This module covers the diagnostic framework, physical health risks, and psychiatric comorbidities associated with addiction, with a specific focus on urban Nigeria.

## Definition and Diagnostic Framework
*   **Substance Abuse:** Harmful use of psychoactive substances despite negative consequences.
*   **Key Features:** Loss of control, cravings, compulsive consumption, and withdrawal symptoms.

## Regional Context: South-West Nigeria
*   **Prevalent Substances:** Alcohol, Cannabis, Tramadol, Codeine, and Tobacco.
*   **Hotspot States:** Lagos, Ogun, and Oyo.
*   **High-Risk Groups:** Commercial motorcyclists, artisans, and urban youth.

## Health Impacts
*   **Physical:** Liver cirrhosis, hypertension, gastrointestinal bleeding, lung cancer, and COPD.
*   **Infectious Diseases:** Increased transmission risk for HIV/AIDS, Hepatitis B, and Hepatitis C through injection drug use.
*   **Mental Health:** Strong correlation with depression, anxiety, and psychosis.

## Dual Diagnosis and Relapse
*   **Dual Diagnosis:** Co-occurrence of substance use disorder and psychiatric illness (e.g., cannabis-induced psychosis).
*   **Relapse Loop:** Cycle involving initiation, regular use, dependency, withdrawal, and relapse.

## Socio-Economic Consequences
*   **Family Level:** Domestic violence and child neglect.
*   **Economic Level:** Loss of productivity and rising healthcare costs.
