Most notably, cannabis has had a long association among musicians and the music industry.

Multiple review studies have confirmed these reports. American poet Allen Ginsberg's 'First Manifesto to End the Bringdown' (1966) noted that 'the vast majority all over the world who have smoked the several breaths necessary to feel the effect, adjust to the strangely familiar sensation of Time slow-down.' American physician Jerome Groopman of Harvard Medical School, reported that the 'perception of time is altered, generally with perceived time faster than clock time' in people who have ingested cannabis. Later, in 1958, South African physician Frances Ames studied the effects of cannabis extract, noting the 'disordered time perception' experienced by her subjects where 'brief periods seemed immensely long'. Moreau published his findings in Hashish and Mental Illness: Psychological Studies (1846), noting that hashish caused 'errors of time and space' and 'time dragging'. French physician Jacques-Joseph Moreau studied the effects of cannabis with the help of Gautier and other artists who experimented with hashish in the Club des Hashischins. Notable discussions of the effects occur in 'Le Club des Hachichin' (1846), a work by French poet Théophile Gautier, and in Les Paradis Artificiels (1860), a work by Charles Baudelaire. Reports of the effects of cannabis on time perception can be found first in arts and literature, and then in medical reports and studies.
