“The connection between music and cannabis has a rich history, dating back to the emergence of jazz in the early 20th century. Many pioneers in this improvisational art form were regular users of cannabis, including Louis Armstrong and Dizzy Gillespie.
Some theorists postulate that cannabis’ effects on an individual’s sense of timing might be responsible for its appeal amongst musicians. Previous studies have shown that cannabis speeds up our internal clocks, making external “real world” time appear to pass slower.
The auditory enhancing effects of cannabis might also have potentially therapeutic applications. Fachner notes that based on his results and anecdotal evidence, cannabis could help those with hearing impairments fine tune their listening ability, more effectively differentiate the source of sounds, and hear higher frequency sounds more clearly.”
