relative to the definition of hemp.
SB 461 updates New Hampshire's legal definition of "hemp" to require that the total tetrahydrocannabinol (THC) concentration - including tetrahydrocannabolic acid (THCA) - must not exceed 0.3% on a dry weight basis. This change directly affects hemp farmers, product manufacturers, and state regulators by establishing a clear standard for legal hemp under state law. The bill modifies existing law to align with the federal definition of hemp, which includes THCA in THC calculations, ensuring consistency for businesses selling hemp-derived products. The law will take effect 60 days after enactment.

MINOR
The House amended the Senate version of SB 461 by changing the hemp definition from 'delta-9 tetrahydrocannabinol concentration' to 'total tetrahydrocannabinol (THC) concentration.' This makes the first sentence of the definition consistent with the existing second sentence, which already defined total THC as including all forms of THC such as THCA. The change narrows the scope of what qualifies as hemp by ensuring the 0.3 percent threshold applies to all THC forms, not just delta-9 THC.
DEFINITION
Changed the hemp definition from 'delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent' to 'total tetrahydrocannabinol (THC) concentration of not more than 0.3 percent.' This broadens which THC forms count toward the 0.3 percent limit, making it harder for a product to qualify as hemp since all THC isomers and acids now count, not just delta-9 THC.
TECHNICAL
Corrected a typo in the section heading: 'Defintions' changed to 'Definitions.'
