Yes yes! This is a very good point.
There is something very powerful about the "unknown". I think the whole novelty of trying a "new" drug activates discreet brain regions involved in the placebo effect.
Just like you will never get the same rush from trying a roller coaster for the 2nd time. Quite simply because your brain knows it has experienced this before, and therfore seeks to process the experience with other circuitry.
