Thanks, this is my own conclusion and it's wonderful to see it so assertively stated.

I once spent over an hour at a Dunkin Donuts, drinking a coffee and using their wifi for work. I was struck by:

• the massive amounts of sugar on their menu
• what didn't have sugar had starch
• the people who lined up for another "hit"
• the various ways the drug was dressed up and flavored and re-shaped
• adding caffeine to the drug super-powered it

I had a half-caff with heavy cream. It was literally the only thing I could get.
