Sec. 781. <<NOTE: Effective date. 7 USC 1639o note.>> Effective
365 days after the enactment of this Act, Section 297A of the
Agricultural Marketing Act of 1946 (7 U.S.C. 1639o) is amended--
...
``(A) In general.--The term `hemp' means the plant
Cannabis sativa L. and any part of that plant, including
the seeds thereof and all derivatives, extracts,
cannabinoids, isomers, acids, salts, and salts of
isomers, whether growing or not, with a total
tetrahydrocannabinols concentration (including
tetrahydrocannabinolic acid) of not more than 0.3
percent on a dry weight basis.
...
``(C) Exclusions.--Such term does not include--
...
``(iii) any intermediate hemp-derived
cannabinoid products which are marketed or sold as
a final product or directly to an end consumer for
personal or household use; or
``(iv) any final hemp-derived cannabinoid
products containing--
``(I) cannabinoids that are not
capable of being naturally produced by a
Cannabis sativa L. plant;
``(II) cannabinoids that--
``(aa) are capable of being
naturally produced by a Cannabis
sativa L. plant; and
``(bb) were synthesized or
manufactured outside the plant;
or
``(III) greater than 0.4 milligrams
combined total per container of--
``(aa) total
tetrahydrocannabinols (including
tetrahydrocannabinolic acid); and
``(bb) any other
cannabinoids that have similar
effects (or are marketed to have
similar effects) on humans or
animals as a
tetrahydrocannabinol (as
determined by the Secretary of
Health and Human Services).
...
``(C) The term `container' means the innermost
wrapping, packaging, or vessel in direct contact with a
final hemp-derived cannabinoid product in which the
final hemp-derived cannabinoid product is enclosed for
retail sale to consumers, such as a jar, bottle, bag,
box, packet, can, carton, or cartridge.

SEC. 2019. <<NOTE: Applicability.>> SECTION 781 EXTENSION.
Until December 11, 2026, the amendments made by section 781 of
division B of Public Law 119-37 (7 U.S.C. 1639o note) shall only apply
with respect to products described in paragraphs (1)(C)(ii)(I) and
(1)(C)(iv)(I) of section 297A of the Agricultural Marketing Act of 1946
(7 U.S.C. 1639o) (as amended by such section 781).

Hexahydrocannabinol is currently controlled in
schedule I as a tetrahydrocannabinol.
...
Thus, only tetrahydrocannabinols in or derived from the cannabis
plant--not synthetic tetrahydrocannabinols--are excluded from control
as ``tetrahydrocannabinols in hemp.'' To clarify further,
tetrahydrocannabinols produced through chemical conversion, even when
hemp derived are considered synthetically produced for purposes of the
CSA, do not qualify as ``tetrahydrocannabinols in hemp'' under the AIA.
