Chris Bennett provides some research supporting the notion that Haoma may have been the ancient Persian word for a connection concoction of cannabis, ephedra (to keep an individual awake) and other supplements/stimulants.
The Temple site at BMAC was devoted to the preparation of the Haoma, according to the Russian archaeologist Victor Sarianidi, where he claims evidence of cannabis, ephedra, and in some later cases opium, was ground and strained for the preparation of Haoma, has been found. 
It has been suggested that the Chinese name for cannabis, Hu-Ma, Became Haoma as it traveled into the BMAC region, carrying its Chinese name with it.
