I was mistaken.  It was more than two months ago that Old Soul denied the existence of "hash oil".

There is no such thing as "hash oil". No one is going to go to the expense of making hash, then turn it into oil. Call it what it is...an extract of cannabis.

"Hash oil
"Hash oil is an oleoresin obtained by the extraction of marijuana and/or hashish. The tetrahydrocannabinol (THC) content of hash oil varies tremendously, since the manufacturers use a varying assortment of marijuana plants and preparation techniques. Dealers sometimes cut hash oils with other oils."
""Samples seized across the United States by the Drug Enforcement Administration over an 18-year period (1980–1997) showed that THC content in hashish and hashish oil averaging 12.9% and 17.4%, respectively"
