Increased Risk of Substance Abuse in Nigeria: A Growing Public Health and Mental Health Crisis

Substance abuse has become one of the most pressing public health challenges in Nigeria. The misuse of alcohol, prescription medications, cannabis, opioids, tramadol, codeine-containing cough syrups, and other psychoactive substances is affecting millions of Nigerians, particularly young people. Beyond addiction, substance abuse contributes to poor mental health, chronic diseases, violence, accidents, unemployment, and family breakdown.

According to the first nationwide Drug Use Survey conducted by the Nigerian government with support from the United Nations Office on Drugs and Crime (UNODC), approximately 14.3 million Nigerians aged 15–64 years reported using drugs in the previous year—about 14.4% of the population, a prevalence more than twice the global average reported at the time.

What Is Substance Abuse?

Substance abuse refers to the harmful or inappropriate use of psychoactive substances, including illegal drugs, prescription medicines taken without medical supervision, alcohol, tobacco, and inhalants. Continued misuse can lead to substance use disorder, dependence, physical illness, mental health disorders, and social problems.

Why Is Substance Abuse Increasing in Nigeria?

Several factors contribute to the rising burden:

1. Economic Hardship

High unemployment, poverty, inflation, and financial stress push many individuals to use drugs as a temporary escape from emotional and economic pressures.

2. Mental Health Challenges

Depression, anxiety, trauma, and chronic stress often coexist with substance abuse. Some individuals self-medicate with drugs instead of seeking professional care.

3. Peer Pressure

Young people are particularly vulnerable to experimenting with substances because of peer influence, social acceptance, or curiosity.

4. Easy Access to Drugs

The availability of prescription opioids, tramadol, codeine-containing products, cannabis, and other psychoactive substances through illegal channels increases the likelihood of misuse.

5. Family and Social Factors

Poor parental supervision, family conflict, domestic violence, neglect, and adverse childhood experiences increase vulnerability.

6. Poor Awareness

Many people underestimate the dangers of recreational drug use or mistakenly believe some substances improve performance, reduce stress, or enhance social confidence.

Prevention Strategies

• School-based prevention programs
• Community awareness campaigns
• Responsible prescribing of medicines
• Early screening and counseling
• Access to evidence-based treatment and rehabilitation

When to Seek Professional Help

Professional support should be sought if someone:

Early intervention significantly improves recovery outcomes.

Conclusion

Prevention through education, mental health support, early intervention, and accessible treatment remains the most effective strategy.

If you or someone you know is struggling with substance misuse, seeking professional medical advice early can prevent long-term health complications and improve quality of life.
