"There's no question," says Roland R. Griffiths, PhD, professor in the departments of psychiatry and neuroscience at Johns Hopkins University School of Medicine in Baltimore and a veteran researcher in the area. Caffeine is addictive for some people, he says. "Caffeine does produce dependence, and caffeine withdrawal is a real syndrome."
But George Koob, PhD, professor of the Committee on the Neurobiology of Addictive Disorders at The Scripps Research Institute, San Diego, disagrees. "While it is possible to be addicted, most people are not," he says. "I think most of my colleagues would agree."

But honestly, now all you’re arguing is that nicotine should be regulated because it’s more addictive than caffeine. A real point of victory there. Sarc.
