This bill introduces a new section to RSA 644, specifically section 644:5-b, which prohibits the unlawful sale of certain inhalants and chemical compounds for recreational use. The bill defines unlawful sale as the act of selling, offering for sale, or transferring compounds that include butyl nitrite, isobutyl nitrite, secondary butyl nitrite, tertiary butyl nitrite, nitrous oxide (commonly known as "laughing gas"), and amyl nitrite (known as "poppers" or "snappers"). It establishes that any person or business found in violation of this section will be guilty of a class A misdemeanor. The bill also outlines exceptions for the sale of these substances when intended for specific uses, such as medical purposes, manufacturing, food preparation, or automotive applications, provided that the purchaser is at least 21 years old.

Additionally, the bill includes a rebuttable presumption against the exceptions if the substances are flavored or marketed in a way that suggests they have the taste or smell of food. The effective date for this act is set for January 1, 2027. The fiscal impact of the bill is indeterminable, as it may affect the judicial and correctional systems, potentially influencing costs related to prosecution, incarceration, probation, and parole for the state and local governments.
