Is coffee the key component of productivity?

I came across this cartoon and it made me wonder if coffee really is the key component of productivity. I think that I make myself believe that coffee will increase my productivity and reduce procrastination. But who am I kidding? I believe that it definitely helps you stay awake, but it certainly doesn't make you any more motivated or smarter. I work for a company which has a coffee station with 10 different coffee flavors. Most of the time I go for the well known Colombian coffee. Just the other day I figured out that I have been taking non-caffeinated natural Colombian coffee! But the first thing I say when I get to work is, hold on, let me get some caffeine first... Maybe I should rethink this coffee drinking habit...
