CBDH, a Newly Discovered Cannabinoid Effective for Pain

CBDH was found to have strong pain killing effects in mice at an abdominal injection dose of 1 and 2 milligrams per kilogram (about 75 and 150mg per 165 lbs of human), but NOT at a higher dose of 5 mg/kg.  This is consistent with the Biphasic properties of many of the cannabinoids, like THC and CBD. So there's actually a clinical reason why you should "start low and go slow".

The Regional European Development Fund financed this research project in Florence, Italy by the same researchers that discovered CBDP and THCP. They also discovered THCH, but the quantities were insufficient for further research.

Interestingly, they were not able to determine the origins of CBDH and THCH in the "Family Tree" of cannabinoids.
