> That's because the loophole doesn't exist. It's an obviously flawed interpretation of the 2018 Farm Bill which isn't likely to hold up in court when it's finally tested there.
It's been tested somewhat (interestingly, in a trademark case which rested on whether the infringed trademark was for a legal product) and it has succeeded at the Circuit Court level. AK Futures LLC v. Boyd Street Distro, LLC, 9th Cir. No. 2-56113 (May 19, 2022):
Importantly, the only statutory metric for distinguishing controlled marijuana from legal hemp is the delta-9 THC concentration level. In addition, the definition extends beyond just the plant to “all derivatives, extracts, [and] cannabinoids.” 7 U.S.C. § 1639o(1). The use of “all” indicates a sweeping statutory reach. See Lambright v. Ryan, 698 F.3d 808, 817 (9th Cir. 2012) (“The common meaning of the word ‘all’ is ‘the whole amount, quantity, or extent of; as much as possible’ . . . .” (quoting All, Merriam-Webster (online ed., visited Oct. 4, 2012))). This seemingly extends to downstream products and substances, so long as their delta-9 THC concentration does not exceed the statutory threshold.
Of course, as this was on an appeal of a denial of a preliminary injunction, the ruling is framed in likelihood of success rather than absolute terms, but its a pretty strong negative indicator for your argument that this is a clearly incorrect interpretation that no court would take seriously, since both the District Court and the Circuit Court very much took it seriously.
