I came home from a trip the other day with a small plastic bag filled with 4 ounces of brown powder that, truth be told, made me a little nervous.
The powder had a strong odor that reminded me of badly burnt coffee, with perhaps a note of brown sugar.
I didn't dare open that bag. It contained crude caffeine, about 90 percent pure. That small bag held as much caffeine as 1,000 tall lattes from Starbucks, or 2,000 cans of Coke or Pepsi. It was enough to kill several people.
