If It Feels Good, Must Be Dopamine

Did they spend a lot of money on this study to find this out?
And who gets to participate in these studies?

"If you take just a sip of beer, and moments later—before you’ve had close to enough alcohol to get intoxicated, perhaps even before the beer has hit your stomach—feel a distinctly pleasurable sensation, it might not be strictly due to subtle aromas that result from the beverage’s blend of malt, hops and yeast. The cause of your pleasure might be due to tangible changes in your brain chemistry—specifically, a surge in levels of the neurotransmitter dopamine."

Do they know about other things leading to surges in dopamine? Will there be more studies? They could just pay me to tell them how to increase the dopamine and pleasure in life.

Or they could just guess, like this: "The researchers believe this could be a clue as to why some people are predisposed towards alcoholism—and why it’s more difficult for them stay on the wagon if they’re trying to quit." Yes, a clue!
