Feeling Good

Abigail Zuger's review of David Casarett's Stoned: A Doctor's Case for Medical Marijuana says a researcher commented to Casarett: “Any drug that makes you feel good has a black mark against it. And that’s true no matter how effective a drug might be.”

Is this related to H.L. Mencken's definition of Puritanism as "the haunting fear that someone, somewhere, may be happy"?
