11-hydroxy-Tetrahydrocannabinol
Occurrence: When Delta-9-THC is ingested, the liver turns it into 11-hydroxy-THC. This can be bought in a lab-made setting, but is not recommended.
Psychoactive: Yes
Effects: A much stronger THC. Some cannabinoids are not properly heated, or properly digested. It seems that indica-esque cannabinoids/terpenes stick around moreso through the cooking process. Because of this, most edibles are sleepy/giggly.
Potency: About 10x-11x as potent, thanks liver!
Discovery: 1941
Note: - The best way to get 11-hydroxy is to eat weed. The worst way is vapes. 11-hydroxy-THC is not nearly as heat-stable as THCa, meaning much of it is being destroyed. Also, it is not fully known if 11-hydroxy-THC is absorbed into the lungs as readily as other forms.
