What predicts cannabis use among Nigerian secondary school students?

Cross SectionalModerate evidence
The takeaway

Among 4,078 Nigerian secondary school students, having friends who use drugs, parental smoking, and low risk perception were the strongest predictors of cannabis and illicit drug use.

Public health researchers, African drug prevention program designers, and adolescent health specialists.

Friend drug use, parental smoking, and low risk perception were top predictors

What the researchers found

In a survey across all six Nigerian geopolitical zones, cannabis and illicit drug use among adolescents (mean age 14.7) was associated with older age, single-parent households, parental smoking, parental permissiveness to drink, having drug-using friends, low perceived risk of harm, and positive beliefs about drugs. Socioeconomic status predicted cannabis but not other drug use.

Why it matters

Cannabis use among African youth is growing but understudied. This is one of the few large-scale studies providing nationally representative data on risk factors for adolescent cannabis use in Nigeria.

The numbers in context

4,078 students; mean age 14.7; 32 schools; 6 geopolitical zones; key predictors: friend drug use, parental smoking, low risk perception, positive drug beliefs.

How the study worked

Cross-sectional survey of 4,078 secondary school adolescents from 32 schools across all six geopolitical zones of Nigeria, using multilevel logistic regression models.

What this study cannot tell us

Cross-sectional design; self-reported drug use in a context where it is illegal; school-based sample excludes out-of-school youth who may have higher use rates; specific substances within "illicit drugs" category not always distinguished.

How to read the evidence

Moderate: large nationally representative sample with multilevel analysis, but cross-sectional and self-reported.

When this study was published

Published 2020.

The bigger picture

The risk factors identified mirror those found in Western countries (peer influence, parental behavior, risk perception), suggesting universal prevention approaches may be adaptable across cultural contexts.

Questions still open

  • Would culturally tailored prevention programs addressing these specific risk factors reduce cannabis uptake in Nigerian schools?

Common questions

What most strongly predicted adolescent cannabis use in Nigeria?
Having friends who use marijuana or other drugs was one of the strongest predictors, along with parental smoking, low risk perception, and positive beliefs about drug use.
Are the risk factors different from Western countries?
The key risk factors (peer influence, parental modeling, risk perception) are similar to those found in Western studies, suggesting some universality in adolescent substance use predictors.
