THC-O stands for tetrahydrocannabinol acetate. THC acetate ester can be synthesized from Delta 8 or Delta 9 THC.
Following legal changes in the USA since around 2018, especially the legalisation of cannabis in an increasing number of states and the passage of the 2018 Farm Bill which eased restrictions on the cultivation of industrial hemp, THC-O-acetate has become increasingly available as a recreational drug, initially in the USA but subsequently in other countries also.
“The effect of the THC-O acetate is more spiritual and psychedelic than that of the ordinary product. The most unique property of this material is that there is a delay of about thirty minutes before its effects are felt.” – D. Gold in his book Cannabis Alchemy.
THC-O acetate ester was investigated as a possible non-lethal incapacitating agent as part of the Edgewood Arsenal experiments at some point between 1949 and 1975. It was noted to have about twice the capacity to produce ataxia (lack of voluntary coordination of muscle movements) as did THC when administered to dogs.
“Like most cannabinoids other than CBD and Delta 9, little is known about the short and long-term effects or safety of this compound. We do know that it has been reported to be as much as 3 times stronger than delta 9. It tends to take longer to take effect (as much as 60 minutes after inhalation to feel full effects), but once it does more users report an almost “spiritual” sensation that isn’t found with any cannabinoid. Do not consume this product without approval from a doctor.”- 3CHI
