New Hampshire's medical marijuana bill, House Bill 648, passed the House and Senate in 2009 but was vetoed by the Governor and fell only two votes short of becoming law.  Here's the full story:

After hearing testimony from patients and experts in March, 2009, the House Health, Human Services, and Elderly Affairs (HHS) Committee voted 13-7 that HB 648 "Ought to Pass."  Then, March 25, the bill was passed by the full House in a 234-138 vote.  

The Senate Health and Human Services Committee heard testimony in April and voted 4-1 to recommend that HB 648 "ought to pass."  Then, April 29, the full Senate voted 14-10 to pass the bill, with minor changes. 

Unfortunately, Governor John Lynch then stepped in and privately suggested to legislators that he would veto the bill if it came to his desk as written.  Rather than approving the Senate's minor changes, the House opted for a "committee of conference" to rework the bill.

The bill as it was passed originally would have allowed qualifying patients to cultivate up to six plants and possess up to two ounces.  Although 13 states allow qualifying patients to cultivate their own plants, this was the part Governor Lynch objected to most strenuously.  The revised bill instead allows for the creation of 3-5  non-profit "compassion centers" that would distribute marijuana to qualifying patients.

The House and Senate voted June 24 to approve the amended bill, but even though it had been amended to address Governor Lynch's stated concerns, he vetoed the bill July 10.

When the vote to override Gov. Lynch's veto was held Oct. 28, the House voted by more than a two-thirds (240-115) margin for the override, but the effort fell two votes short of reaching two-thirds in the Senate (14-10).
