Best known for:

Being a fairly quick hitting and euphoric cannabinoid 


D8 THC-H has a mildly high viscosity. It is very hard to push out of a syringe at room temperature.

Is it a phytocannabinoid? (naturally occurring cannabinoid)

D8 THC-H is a phytocannabinoid

My Opinion

D8 THC-H is a bit of a letdown for me. While the price cut compared to D9 THC-H is appealing, I’m not sure this cannabinoid has much of a place in any blend that is not specifically for creative work - and even then I’d suggest you add a varin like HHCv to the blend because of the sedation that takes over the stimulation after the come up. I think you can have your head screwed on straight a lot easier on D8 THC-H than D9 THC-H, but beyond that, it’s just generally not as good. The power level is knocked down as well, feeling around 1/2 the power of THC-P. Maybe as time goes on I will find another use for this cannabinoid, but for the time being unless you are making a creative blend and are planning to throw a varin in with it I might just skip this one


What can D8 THC-H do for a blend?
  • Add euphoria

  • Add mild power

  • Add a creative feeling stimulation

  • Add a head buzz to the beginning of the high
