Proponents say greenhouses will lower patient prices; opponents warn of program expansion

Summary
SB 468 would allow limited greenhouse cultivation by regulated alternative treatment centers (ATCs). Proponents (industry, medical board) argue it reduces energy costs and patient prices while keeping testing and security; opponents warn it risks program expansion and notice rules could politicize local sites.
Sen. Tara Reardon introduced SB 468 FN as a measure to allow regulated alternative treatment centers (ATCs) to operate additional greenhouse cultivation locations subject to department rules, testing and security requirements. Reardon and multiple supporters told the House Health Committee the bill has been refined to address prior concerns and has recently passed the Senate.
Opponents at the hearing, including Sue Hamola of the New Hampshire affiliate of Smart Approaches to Marijuana, said the therapeutic cannabis program was created with finite boundaries to prevent proliferation and that the proposed changes risk expanding the program beyond its original intent. Hamola flagged a provision requiring the department to solicit input from qualifying patients and caregivers near a proposed cultivation site, warning it could effectively mobilize cardholders to lobby particular towns.
Terry Kernark, chair of the Therapeutic Cannabis Medical Oversight Board, testified the board approved the bill by a 7‑0 vote (one abstention), emphasizing that greenhouse cultivation can lower production energy costs and reduce prices for patients while maintaining mandated security and laboratory testing. Kernark said greenhouse buildings would be required to meet existing security standards and that the department could adopt greenhouse‑specific rules if needed.
Matt Simon of Granite Leaf Cannabis, representing industry operators, said New Hampshire’s ATCs already test every batch and comply with labeling and potency rules. He provided enrollment and price context, estimating about 17,500 registered patients in the state and saying ATCs have reduced prices in recent years (he cited current company price points of $33–$39 for an eighth of an ounce and noted Maine retail prices can be much lower). Simon said greenhouse cultivation is legal in neighboring states and would let New Hampshire operators reduce costs over time.
Committee members asked detailed questions about security, lab testing, THC potency labeling, zoning and the department’s review of proposals. Proponents repeatedly told members that security and testing requirements remain in force and that greenhouses are intended to be subject to the same or stronger safeguards than indoor cultivation.
The public hearing record closed on SB 468 with supporters and opponents on the record; no formal committee action was taken at the hearing.
