thc solubility

hey, this is my first post but ive been lurking around checkin stuff out for awhile.

Anyway i found a study that investigated THC solubility, and luckily they tested it in 70% ethanol (pretty much 151)
They found that THC is soluble at 20.21mg/ml

Heres the actual link: Pharmaceutical composition containing tetrahydrocannabinol and a transdermal/transcutaneous delivery method thereof - US Patent 6503532 Description

I know the questions been asked a million times about whats the saturation point in alcohol, finally here's a clue.
