I have previous experience with cannabis, JWH-018, THJ-018, BB-22, 2NE1, AM-2201 and various blends. This one is quite tame for a cannabinoid, the dry mouth is heavily pronounced. It triggered my HPPD mildly or on an intermediate level, more than with cannabis but less than other cannabinoids.

Summary
AB-FUBINACA is a highly potent synthetic cannabinoid active at very low milligram doses, making accurate measurement with a precision scale absolutely critical. Unlike cannabis, chronic abuse of synthetic cannabinoids has been associated with multiple deaths and hospitalizations with more dangerous side effects. The substance is insoluble in water but dissolves in ethanol and lipids.

Tolerance
Build-up
develops over weeks of regular use via CB1 receptor downregulation
Reset
2–4 weeks for most users; heavy users may need longer
Tolerance Decay
Full tolerance
3d
Half tolerance
21d
Baseline
~28d
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.

Hood9466 I have experienced lung cancer and did not want to smoke anything. The product did intrigue my addiction-prone self. I saw the dosage and I though if I wet the edge of knife blade and ingest it, I couldn't possible go wrong. My wife discovered me in a non-coherent state and was concerned.

Male, Age 30, 85kg/187lbs I have been a HEAVY user of synthetic cannabinoids, starting with the original Spice Gold in 2007, then moving onto numerous other blends, then pure powders. My last 5 day binge on UR-144 last December prompted me to quit “noids” for good (not for the first time I have to add).
I consumed synthetic cannabinoids for the first time last year, because i have to do hair screenings for one year. The first time i smoked some blend with probably second generation noid on a party and was absolutely floored in a bad way. A lot of paranoia and psychosomatic discomfort.
