Dr. John Erhabor: A Leading Voice in Public Health Research

Dr. John Erhabor’s journey in public health began at Obafemi Awolowo University, where he completed his medical training. While at the university, Dr. Erhabor became deeply involved in community outreach programs, providing free healthcare to local communities under several institutions. His passion for serving others led him to pursue a broader understanding of public health.

After completing his internship at Obafemi Awolowo University, Dr. Erhabor served with the Nigerian Airforce in Calabar, further developing his skills in healthcare and leadership. However, driven by his growing interest in public health, Dr. Erhabor took a bold step and paused his medical residency. He moved to the United States to pursue a master’s degree in public health at Johns Hopkins Bloomberg School of Public Health, which is widely regarded as the top public health institution in the country.

At Johns Hopkins, Dr. Erhabor joined a research group focused on pressing public health issues. His recent work includes two significant studies that have impacted the field. One of his most recent publications, featured in JAMA Network Open, provided vital insights into e-cigarette use across the United States.
The study highlighted how e-cigarette use remained prevalent during the COVID-19 pandemic, particularly among young adults aged 18 to 24 years. The findings were remarkable, as many young users had never used combustible cigarettes. This research is helping to shape the conversation about the risks of e-cigarettes and the need for public health policies that specifically address this demographic.
His study highlights the importance of strategic policy planning to ensure that treatments like semaglutide are accessible to those who need them most. Dr. Erhabor advocates integrating semaglutide into healthcare systems through value-based approaches, such as clinical pathways and cardiometabolic clinics. He also stresses the need for expanded insurance coverage and negotiating lower drug costs to make the treatment more accessible to underserved communities.

Addressing the Global Challenge of E-Cigarette Use
As global markets, including developing economies, face increasing challenges related to tobacco and nicotine use, Nigeria has emerged as a prime target for the expanding e-cigarette market. E-cigarette sales have gained significant traction in countries like the United States. Marketers will likely look toward developing economies with more lenient regulations as regulations tighten in these regions. Nigeria, with its large youthful population and limited tobacco control policies, has seen a rise in e-cigarette consumption. The growing prevalence of e-cigarettes in Nigeria is fueled by factors such as aggressive marketing, easy accessibility, and the allure of vaping culture, as pointed out in a publication by Oluwatobi E Adegbile et al. in 2024 titled “E‐cigarettes in Nigeria: A scoping review of evidence” published in scientific health reports. Despite the absence of comprehensive national data, anecdotal evidence indicates a worrying increase in e-cigarette use among Nigerian youth, raising concerns about nicotine addiction and long-term health risks. This highlights the critical need for public health policies that address e-cigarette use and its effects, particularly in developing countries like Nigeria.

Given Dr. Erhabor’s extensive expertise in public health, experts like him can play a pivotal role in conducting research that addresses key public health challenges in Nigeria. Such research could provide the critical evidence needed to guide the development of effective policies and monitor the success of existing ones. With Nigeria’s growing concerns around e-cigarette use and tobacco-related diseases, Dr. Erhabor’s work could be instrumental in shaping policies that protect public health and address these emerging issues. His research could offer vital insights for policymakers, ensuring that health strategies are evidence-based and responsive to Nigeria’s population’s unique challenges.
