New Hampshire lawmakers are attempting to override a gubernatorial veto of legislation that would expand medical marijuana cultivation via greenhouses, according to Marijuana Moment. The governor vetoed the bill on June 12; the override effort began this week. The measure, which had drawn scrutiny over local control issues during earlier debate, represents a shift in legislative priority toward cultivation access rather than broader legalization.

The override attempt occurs as New Hampshire's medical marijuana program shows expansion momentum: the state added 2,100 new patients over the past year, per Concord Monitor reporting. However, the legislature's broader cannabis agenda has stalled—the Senate rejected House-passed legalization bills three times since February 2026, and no marijuana policy changes advanced in 2025. The greenhouse override suggests lawmakers may find more consensus on production expansion within the existing medical framework than on full legalization.

Watch whether the override secures the supermajority required. Success would signal legislative appetite for incremental medical-program growth despite gubernatorial resistance, while failure would reinforce that New Hampshire's cannabis reform momentum remains constrained.
