In 1994, the Johns Hopkins School of Medicine confirmed what anybody who’s tried to give up coffee suspected: caffeine is chemically addictive. It’s also the world’s most popular psychoactive drug… 80% of American adults consume it in some form. Withdrawal symptoms from caffeine are so dreadful that they are cited as a mental disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders.
Here to unpack the chemical effect that caffeine can have on the human brain is Joseph Stromberg, journalist and science writer based in Washington, D.C. His work has been featured in Smithsonian Magazine and Slate.
