The New Hampshire Senate approved a measure Thursday that would remove criminal penalties for cannabis possession. While there are still a few hurdles to clear, the decriminalization bill is widely expected to become law.

Sununu tweeted on Thursday: “I look forward to signing House Bill 640 into law.”

Shortly after he was elected this past November, the Republican governor said he supported cannabis decriminalization but wasn’t ready to endorse a legal, regulated market. “[To] simply jump all the way to full legalization is not a step that we should be looking at right now,” he told Seacoast Media Group in November 2016.

“New Hampshire remains the only New England state where an adult can be arrested, face up to a year in jail, and suffer a lifelong criminal record simply for possessing a personal use amount of marijuana,” NORML Executive Director Erik Altieri said in a statement Thursday. “We commend lawmakers for finally correcting this injustice.”

Proponents have also argued that law enforcement resources could be better spent addressing the ongoing opioid crisis, which has hit New England states hard in recent years—with New Hampshire among the worst in terms of opioid overdose deaths.

Under the New Hampshire measure, possession of up to three-quarters of an ounce would be punishable by a $100 fine for a first or second offense. That penalty would climb to $300 for a third offense within three years of the first offense. A fourth offense within a three-year window could be charged as a misdemeanor, but there would be no arrest or possibility of jail time.

“This is a very important reform for the Granite State, and it has been a long time coming,” said Matt Simon, New England political director for the Marijuana Policy Project. “The walls of prohibition are crumbling in New England and across the United States. It’s encouraging to see New Hampshire finally begin to catch up with neighboring states by passing decriminalization.”

Both Maine and Massachsuetts voted in November to legalize cannabis for adult-use. On Wednesday, the Vermont Legislature voted to legalize cannabis cultivation and possession, but not commercial production or sales. That bill awaits the signature of Gov. Phil Scott, who hasn’t yet said whether he’ll approve it. He’s previously made comments against legalization.

In Delaware, a bill that would legalize adult-use cannabis was released Wednesday by a House committee and now goes to the full House for consideration. The legislation, which seeks to regulate and tax cannabis in the same manner as alcohol, cleared its first legislative hurdle on a 10-2 vote in the House Revenue and Finance Committee.

While the bill would not allow people to grow their own, it would allow adults over age 21 to legally possess less than an ounce of cannabis for personal use.
