Hemp-Derived Delta-9 vs. Marijuana
The key difference between hemp-derived Delta 9 THC and marijuana is how much THC is naturally present in the plant and how it is extracted.
Legally, hemp is defined as a cannabis plant that contains 0.3 or less THC at its dry weight, while “marijuana” is a cannabis plant that contains more than 0.3 THC at its dry weight.
Hemp-derived Delta-9 THC is extracted from hemp plants that contain less than 0.3 Delta-9 THC by dry weight, as mandated by the 2018 Farm Bill which makes it federally legal.
In other words, when all of the "water" from a hemp plant is removed, the Delta-9 percentage is based on the remaining dry weight. If the number remains below .3, the plant is compliant.
To remain compliant, manufacturers use processes like isomerization or extraction from large amounts of hemp biomass to produce the legal limit of Delta-9 THC in consumable products. This allows it to be sold nationwide, even in states where marijuana remains illegal.
Marijuana, on the other hand, naturally contains higher concentrations of Delta-9 THC, often 15-30 THC or more. Because of this, marijuana-derived Delta-9 remains federally illegal, though individual states have legalized it for medical or recreational use.
While both sources create the same psychoactive THC, the difference in legal status and sourcing makes hemp-derived Delta-9 a more widely accessible option.
