“Caffeine is the most commonly used mood-altering drug in the world”

I am now +1 week cafeeine free. It was one of my New Year’s resolutions. I am drinking decaf in the morning, and laying off sodas (which I have been for a while now).

And after reading articles like this one by John Hopkins Medical Center, with words like “mood altering drug” and “reinforcer” , I am glad to have quit this particular drug cold turkey.

Question: How do you view America’s addiction to caffeine?  Good, bad, or neutral?
