A recent study described in the article "Music Linked to Marijuana Use" illustrates just how badly science can run off the tracks.

One of the more telling aspects of the study indicated that the surveyed students heard about 40 marijuana references in music per day.  However, instead of concluding that marijuana may be a persistent social phenomenon with a relatively high degree of acceptance, the researchers concluded that it was the music that was the causal factor.

I am certainly curious what their criteria for the 40 references is, since the implication is that a significant part of music is dedicated to this topic.  Presumably they didn't resort to the absurdities of the past such as "Magic Carpet Ride" or "Puff the Magic Dragon".

Perhaps I'd better get out to the stalls to ensure that "Beer For My Horses" isn't playing anywhere nearby. There's no telling what kind of equine shenanigans they're prone to get into with that kind of influence.
