Delta-10 THC is the molecular sibling of Delta 8 and Delta 9 THC. However, it’s not a naturally occurring compound in cannabis. Unlike its other siblings, it appears in such minute amounts that consciously extracting it from hemp or cannabis strains would take you a serious amount of time and effort. In many cases, delta 10 can be very elusive that it’s not uncommon for scientists and laboratories to still mistake it for other compounds when they check for it using High Performance Liquid Chromatography, which is the standard for compound testing, explains Extraction Magazine.
