Jimi Hendrix was a heavy user of drugs and was most likely under the influence of other narcotics than specified. He had taken 9 tablets of the prescribed sleeping pill Vesparax, 4 1/2 the prescribed dose. He had also been drinking red wine excessively the night before. So some time on the night of September 18, 1970, Hendrix asphyxiated on his own vomit in his sleep. This was confirmed by the autopsy.
