First Experiments With THC-O-Acetate I have many years of experience with edibles and smoking/vaping D8 and D9 THC as well as various CBD derivatives. I've used Psilocybin mushrooms, LSD, and DMT many many times as well. I purchased a few THC-O-Acetate shots off an online hemp retail website.

Physical data, chemistry & properties O-acetyl-Δ8-THC O-acetyl-Δ8-THC THC acetate ester can be synthesized from THC, or from THCA. The acetylation of THC does not change the properties of the compound to the same extent as with other acetate esters, as the parent compound (THC) is already highly lipophilic, but potency is nonetheless increased to some extent.
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.
