Cannabis (hashish) rosin

Cannabis (hashish) rosin is a solventless extract of cannabis (hashish). It is a byproduct produced by heating the hashish to vaporize the most volatile terpene components. It has a powdery to malleable consistency and varies in color from pale white to brown. It melts instantly when held to temperatures above 150 degrees celsius and becomes a semi transparent mass. It mostly consists of cannabinoids especially tetrahydrocannabinolic acid (THC-A). This is all that is known at this time, but cannabis (hashish) rosin may have a lot of potential as a non-chemical based THC extract in medicine.
