In the article "Caffeine Use Disorder: A Comprehensive Review and Research Agenda."
They posed an agenda for future research that would include clinical, epidemiologic, and genetic investigations to lead to a better understanding of the clinical signs and the prevalence of caffeine dependence, as well as the risk factors and best approaches for treating caffeine addiction.
