2018 Farm Bill hemp legalization (2018)
The federal Farm Bill legalized hemp production and set a 0.3 percent delta-9 THC limit on a dry weight basis. Regulators assumed that threshold was too low to cause intoxication.
Companies found ways to concentrate THC, creating a market for hemp-derived drinks and gummies.
The products spread to states without legal cannabis, including Illinois, and sold outside dispensaries.
That loophole is the legal basis for the drinks now being pushed out of retail.
