Curious as to why music and marijuana make such a good combination? Here's an explanation by neurobiologist, music producer and McGill professor Daniel J Levitin:
"Music combined with marijuana tends to produce feelings of euphoria and connectedness to the music and the musicians. THC - the active ingredient, is known to stimulate the brain's natural pleasure centers, while also disrupting short-term memory. The disruption of short-term memory thrusts listeners into the moment of the music as it unfolds; unable to explicitly keep in mind what has just been played, or to think ahead to what might be played, people stoned on pot tend to hear music from note to note. Subconsciously all of the usual processes of expectation formation are still occurring, but consciously, the music creates what many people describe as a time-standing-still phenomenon. They live for each note, completely in the moment."
