You are correct in that Marinol (dranabinol) is synthetic THC. It is prescribed most commonly for nausea & poor appetite associated with chemotherapy and AIDS. It is sometimes used for intractable chronic pain.Unlike natural occurring THC, it does not lower intraoccqular pressure or exhibit anti-inflammatory properties. It bears no resemblance to CBD, which is cannabidiol, the other major component of cannabis. CBD is non-psychoactive and is a pain reliever, anti-inflammatory, anti-oxidant, muscle relaxant, anti-emetic (decreases nausea), autoimmune modulator, mood stabilizer, appetite suppressant, and anxiolytic (decreases anxiety).
