(San Francisco Chronicle) Coffee is probably the most socially accepted drug in the Western world. Yes, it does intoxicate.

The bitter brew that kickstarts so many early mornings and fuels so many drawn-out workdays causes withdrawal and cravings. Some of them debilitating. It’s safe to say that if you can’t last a day without juicing up on java (or Diet Coke or some other caffeine-infused stimulant), you may be an addict.

That’s why the latest edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders lists caffeine withdrawal and intoxication as mental health disorders that hurt someone’s ability to function.
