Is the answer to the OP, probably the people who made the music?
Drugs/booze and music are linked. Both in the creation and observation of it. It is about finding boundaries and removing them. Finding new ground or a new interpretation or a new language or even courage. Removing boundaries is sometimes about removing ones self. Hense drug use in music.
Obviously you do not need them, but isn't it odd that so many great pieces of music or creative movements were created under the influence of the fashionable drugs of the time?
