It should be noted that stronger cannabinoids like THC-C8 are better enjoyed in a blend. I don't recommend vaping them raw other than once or twice for curiosities sake.

My Opinion
THC-C8 is an intensely stoney and hazy cannabinoid, rivaled only in its ability to lower my eyes and glue me in one spot by HHC-P and HHCPo. The come-up begins with my eyes being forcefully squinted and a feeling of sedation creeping in, which builds into a more and more intense high. The signature of THC-C8 is seemingly its tactile nature as the headband effect is very pronounced and even got so intense on a high dose that it began to feel uncomfortable. It's also common that my arms get heavy and have a "fuzzy" feeling like TV static. The sedation with THC-C8 seems to be quite strong, especially when eaten - I had to drink a coffee in order to stay awake the first time I took it for review. The sedation stuck around longer than any of the other effects.
THC-C8 is quite impressive when it comes to it's strength - in my opinion, it's stronger than everything but the phorols, and even then it might be stronger than THC-P. You certainly need to be careful with dosing on this cannabinoid, especially when it comes to edibles.
It takes a while for THC-C8 to fully take hold but once it does it has a fairly long duration, leaving me still at a 4/10 high with 25mg vaped 6 hours prior.
In the flavor department it falls short but not unusably so - it tastes very chemical-y with notes of rubber and hay. It is seemingly not harsh at all, feeling more like an acetate on the throat than anything else.

swisstargets predicted this to have binding with translocator protein on mitochondria (iirc) and if true, would up your neurosteroid production, making this have potentially lasting gabaergic effects. (The slow rate of their production would make this not addictive like benzos as the time between ingestion and their peak is long)
this stuff made me feel higher the day after. What stoners think happens with stuff like this and THCP, is it takes a while to come up bc its so long lasting, but inhalation is more like IV where you peak very quickly. So for my grogginess and fog to increase morning after tells me something is up. THCP doesn't do this to me, might wake up with it still in system, but doesnt feel like i was given a diazepam in my sleep. I had to run quick predictions on C8 as it was relaxing but more sedating than every other noid and its not even close.
Its JWH-138, Also in Europe they sell it as THC-JD. Dont make that fact bother you though, its not like most JWH analogues! Its weaker and much closer to weed than lets say JWH-018. I would agree with everything Turkey wrote, except I think it does have quite a bit of stimulation too.
