Being a good cannabinoid for potentiation and harshness when vaped


H4CBD has a high viscosity. It is one of the hardest cannabinoids available right now. 

Is it a phytocannabinoid? (naturally occurring cannabinoid)

H4CBD is not a phytocannabinoid

My Opinion

H4CBD is a great noid and one of my favorites for potentiation - when added to a blend it can add a great element to your high - it adds some feeling behind your eyes and a bit of couch lock.


Also unlike other cnoids, H4CBD is very mildly psychoactive to some. 


However, H4CBD has one large caveat - it is HARSH. Of all the cannabinoids I've tried, H4CBD is the hardest on the throat. It can feel like your throat is being sandblasted with tiny particulates. For this reason I would never have H4CBD over 40% in a blend that I plan to vape/

What can H4CBD do for a blend?
  • Great Potentiation

  • Mild Sedation

  • Calming

  • Shatter texture (when mixed with acetates and then stored cold)

  • Anxiety Relief ("taking the edge off")

Other notes:

I have seen on very rare occasions people claim that H4CBD got them the highest they've ever been in their lives, which is extremely peculiar. I would normally not mention this but over the last 2 years, I've seen maybe 10 people say this which makes me wonder if there's some weird enzyme or something that only a small part of the population has.


Either that or they got sold HHC as H4CBD. I keep seeing it being said though, so I feel like there may actually be something to it. If you are a person like this please contact me in chat because I'd like to know how other cannabinoids affect you.

Felt like a psychedelic or like dxm, had auditory hallucinations and closed eyes visuals. Felt like I was gonna die with the worst racing heart.

Yeah I was saying this in my first comment it's got both psychedelic and deliriant (benadryl, prometh, datura .etc) effects at high doses

Yeah like the sounds and visuals weren’t fun they were just scary, like I was in a nightmare. Have had it in vape blends and was fine but when taken as an edible it was completely different, could feel my heart beating against my throat it was so bad. Literally like a delirant and psychedelic with dissociative properties. Also it took so long to sleep cause of my fans white noise warping into looping scary sounds with scary ass visuals

Not to be a wise guy or anything, I am being honest. After experimenting with smaller amounts, I ate 500 mg H4CBD from well-known suppliers and worked out at the gym for an hour and a half. I didn't notice anything. Today I took 300 mg with the same result. I've also taken 300 mg a few times around bedtime and my sleep didn't seem any different. I normally take 300 mg of regular Broad or Full Spectrum CBD distillate before going to the gym, and the same around bedtime. So far, I haven't noticed increased pain relief, sedation, or any other significant effects from H4CBD. I am a more-than-50-year cannabis user with a fairly high tolerance to THC. BTW I believe I read somewhere that CBD normally does not build tolerance the way THC does, due to different ways in works on the cannabinoid receptors, and of course regular CBD usually only affects CB2 receptors. Thank you for this website. I respectfully suggest that the community poll on effects should have an option for "None of the above," for cases where people find that to be the case. I have indeed put a nice amount of H4CBD into a high-potency distillate blend. Perhaps it will work better for me that way.


H4CBD gets me really high, not the highest ive ever been, but it gets me really faded when smoked, taken orally, its much much stronger.

H4CBD works at 5HT2C and mACH receptors as well as cannabinoids in exceeding doses I think that's how it potentiates the psychoactive noids, it gave me visuals similar to mixing a psychedelic with a deliriant but without the headspace at about 2000mg
