<b>Youth Access to Tobacco in Violation of Sales Restrictions: Evidence from the Nigerian Global Youth Tobacco Survey (GYTS)</b>

Abstract

Background: Despite Nigeria’s early commitment to the WHO Framework Convention on Tobacco Control (FCTC), enforcement of Article 16, which prohibits the sale of tobacco to minors remains poorly documented. Since no Global Youth Tobacco Survey (GYTS) has been conducted in Nigeria since 2008, there is a critical evidence gap on how adolescents continue to access tobacco products in violation of legal restrictions. This study provides the first detailed assessment of illegal youth access to tobacco, examining associated demographic, behavioral, and policy awareness factors using nationally representative microdata. Methods: We analyzed the Nigeria GYTS 2008, a cross-sectional school-based survey employing a two-stage cluster sample design across five sentinel areas (Abuja, Cross River, Ibadan, Kano, Lagos). The analytic sample included 2,379 adolescents aged 13–15 years. Complex survey design corrections were applied using Primary Sampling Units (PSU) strata, and final sample weights. The outcome variable—illegal access to tobacco—was defined as purchasing cigarettes without refusal due to age in the past 30 days. Weighted descriptive analyses, chi-square tests, and survey-adjusted logistic regressions (Models 1–3) were performed to identify predictors, including sex, age, rural residence, parental and peer smoking, school type, and awareness of youth-sales laws. Results: Overall, 13.2% (95% CI: 11.6–14.8) of Nigerian adolescents reported successful purchase of cigarettes without being refused for age. Rural youth had higher illegal access (18.5% vs. 11.4%, p<0.001). Adolescents with smoking peers had markedly elevated odds of illegal purchase (aOR=3.48, 95% CI: 2.86–4.25), while those aware of tobacco-age restrictions were less likely to report successful purchase (aOR=0.56, 95% CI: 0.43–0.73). Media exposure to anti-smoking messages showed a modest protective effect (aOR=0.78, 95% CI: 0.64–0.94). Age and male sex were independently associated with higher odds of illegal access. Conclusions: Illegal tobacco access among Nigerian adolescents remains alarmingly prevalent, especially among males, rural youth, and those with smoking peers. Awareness of age restrictions and anti-tobacco media exposure reduces the likelihood of illegal purchase, suggesting that policy enforcement and communication gaps are major barriers to FCTC Article 16 compliance. Strengthening retail surveillance, implementing vendor licensing, and integrating youth-access enforcement into Nigeria’s National Tobacco Control Act (NTCA) 2015 monitoring systems are urgently needed.
