This study was conducted to investigate the prevalence and psychosocial factors undergraduate students at Abia State Polytechnic in Aba, Nigeria, give for engaging in psychoactive substance use. The first hypothesis stated that there will be a high prevalence of psychoactive substance use among undergraduate students of Abia State Polytechnic. The result of the study revealed that the psychoactive substance mainly currently used by the students was Marijuana, followed by Cough syrup/juice. In contrast, the least used is cigarettes, of which the hypothesis was accepted. These statistics indicate not only a significant level of substance use but also a potential normalization of psychoactive substances within the student culture. The high rate of mixed weed usage may suggest that students may be experimenting with various combinations of substances, potentially increasing the risks associated with their use. The significant prevalence of cough syrups calls for concern; such substances are often misused for their psychoactive effects. This can lead to dependency and other health-related issues. The result agrees with the findings of a similar study conducted among undergraduate students, which reported Cough syrup and Marijuana as commonly used substances (Josephine & Oladipo, 2020; Aguocha & Nwefoh, 2021; Oluwakemi et al., 2024). Our findings are in contrast to studies by Florence et al. (2016), where Marijuana was the second psychoactive substance least commonly used by undergraduates in Benin City, Nigeria. The findings from our study corroborate the hypothesis of high psychoactive substance use among the students. This worrisome trend necessitates urgent attention from school authorities, policymakers, and health professionals to implement effective prevention and intervention strategies. The importance of these strategies cannot be overstated in addressing this issue and enhancing the student's overall well-being and academic performance.
The second hypothesis, which stated that psychosocial factors would significantly predict psychoactive substance use among undergraduate students of Abia State Polytechnic, was also accepted. Our findings highlight the significant role of psychosocial factors in predicting psychoactive substance use among students and young people. The results indicate that nearly half of the variability in substance use behaviors can be explained by the psychosocial environment of the students. It further suggests that more favorable psychosocial conditions are associated with lower levels of substance use among students as a means of coping mechanism. Our results are consistent with a study conducted by Sani et al. (2024) in Kaduna, Nigeria, where psychosocial factors such as relief from stress and peer pressure were identified as crucial determinants of substance use among students and young people.
Similarly, a study conducted in sub-Saharan Africa showed that students who experience high levels of stress and low social support are more likely to resort to substance use, highlighting the importance of psychosocial well-being in this demographic (Jumbe et al., 2021). Academic institutions should prioritize the development of supportive psychosocial environments to mitigate substance use among students. However, it is not just about mitigating substance use but addressing the root causes. Activities promoting social support networks, mental health awareness, and stress management could be effective strategies for reducing this level of substance use. The acceptance of this second hypothesis that psychosocial factors significantly predict psychoactive substance use among undergraduate students underscores the necessity of comprehensive and holistic approaches to substance use prevention. It is not enough to discourage substance use but to create an environment that supports students' mental and emotional well-being, thereby reducing the need for such coping mechanisms.
The third hypothesis that demographic variables will jointly predict psychoactive substance use among students of Abia State Polytechnic was supported. Our result reveals significant findings that contribute to our understanding of substance use within the study population. The coefficient of multiple correlation of our data suggests that approximately a quarter of the variations in psychoactive substance use can be attributed to demographic factors such as age, sex, religion, and year of study. This aligns with a previous study in Imo State, Nigeria, that emphasizes the influence of demographic variables on substance use behaviors among undergraduates (Duru et al., 2017).
Regression analysis revealed that age, religion, and year of study were independent predictors of psychoactive substance use in our research. The positive coefficient for age suggests that older students are more likely to engage in psychoactive substance use. This finding is consistent with the work of Sani et al. (2024), which showed that older adolescents and young adults in Kaduna, Nigeria, exhibit higher levels of substance use due to increased independence and exposure to social situations that may promote such behaviors. However, Siro (2014) found that young people are vulnerable to drug and substance abuse globally. The year of study also negatively correlated with psychoactive substance use in our study, suggesting that students in higher academic years may be more focused on their studies and less engaged in substance use. This is consistent with a previous study by Omole et al. (2022), which showed that the level of study independently and jointly predicted psychoactive substance use by students. The negative coefficient for religion indicates that students with stronger religious beliefs may be less likely to use psychoactive substances. This is supported by findings from a study in southeast Nigeria, where more religiously committed students reported less use of psychoactive substances (Kator et al., 2018). Therefore, religion will negatively predict substance abuse.
Our findings underscore the urgent need for action to address the high prevalence of psychoactive substance use and the various psychosocial factors fueling this destructive behavior among undergraduate students at Abia State Polytechnic. These findings likely reflect a broader trend among Nigerian undergraduate students, demanding immediate attention from school authorities to investigate toxic psychosocial factors in the school environment. The creation of a functional and confidential counseling unit that can relate to these students individually is a pressing need. Policymakers and health professionals should also implement effective prevention and intervention strategies without delay. Addressing this issue is not just a matter of enhancing the student's well-being and academic performance, but it is about securing a positive future for our youth.
Limitations
The cross-sectional study used snowball sampling; only a few students responded.
Its results cannot be generalized to the entire population because we did not get a good percentage of the student population. Also, the prevalence of Substance use was determined through a self-reported questionnaire, so 100% reliability cannot be guaranteed due to possible recall bias.
The questionnaire in this study contained many items, and respondents found it challenging to complete. This could lead to answering any response without proper analysis.
Recommendation
We recommend that school management introduce toxicology test screening to help dictate the early use of substances for intervention. This proactive approach can identify students at risk of substance use early, allowing for timely intervention and support.
School management should, as a matter of urgency, introduce a functional counseling unit that will offer individualized and confidential counseling. This personalized approach is crucial in tackling the various psychosocial factors necessitating substance use. Students need a safe space where they can openly discuss their issues and receive tailored support to address their unique challenges.
The National Board on Technical Education (NBTE) should introduce general courses on drug knowledge to sensitize students on the dangers of substance use.
