In today’s world, people are surrounded by more health information than ever before—posters at clinics, videos online, charts in hospitals, and even warning labels on everyday products. But more information doesn’t mean better understanding. In fact, many people are more confused than informed, and that confusion leads to harmful choices—not because they don’t care, but because no one has clearly explained what they need to know in a way that makes sense to them.

This is the heart of what researchers call a health literacy crisis. Health literacy is not about intelligence. It’s about whether people understand how to take a medication, read a vaccine schedule, or safely use something that’s now legal but still carries risks. Many people never got that basic guidance across countries, rich and poor, from America to Nigeria. And it’s costing lives, straining healthcare systems, and widening gaps in health outcomes.

These are revelations in the work of Pearl Oladele and her coauthors, who focus on these issues. In a recent study at Washington State University, she collaborated with some researchers to help lead a project focused on cannabis use among college students.

A statement yesterday by the researchers noted: “With cannabis now legal in many parts of the U.S., there’s a new challenge: young adults are using products they don’t fully understand. Labels are confusing. Potency varies. Some think a soda bottle with ten doses is one serving. That mistake can lead to panic, hospital visits, and long-term consequences.

“Rather than blaming students, Pearl Oladele and her team did something different. They created a video that explained, in clear, everyday language, how cannabis works, what’s legal, what the risks are, and how to avoid getting hurt. The video was voiced by someone who had worked in the cannabis industry—someone students would see as credible. The result? Students walked away feeling more confident about what they knew, more aware of the risks, and better equipped to make safer choices. That change didn’t come from scare tactics. It came from clear, respectful communication.

“But the bigger story isn’t just about cannabis. It’s about how public health information is delivered. Pearl Oladele’s work shows that when people are treated like adults and information is presented in a way that respects their context and intelligence, they listen and act more wisely. This should be a guiding principle for health educators everywhere.

“For policy leaders in the United States, this means rethinking how health campaigns are designed. It’s not enough to create content. That content must be understandable, relatable, and rooted in how real people make decisions. In a diverse country, that includes using voices that reflect the audience’s experience, just like the cannabis video did.”

According to the statement, for countries like Nigeria, the lesson is just as urgent. As health systems deal with growing challenges—from non-communicable diseases to drug misuse to reproductive health—what people need isn’t just access to clinics or medications. They need honest, practical education that explains how to use what’s available, what to watch out for, and how to stay safe in changing environments. That clarity could save more lives than any new policy.

“Pearl Oladele’s contribution to this field reminds us that communication is not just a soft skill; it’s a matter of life and death. With her coauthors, she is helping shift the focus of public health from information overload to real understanding. And that shift is not just vital; it’s overdue,” it added.
