Last week, Governor John Lynch vetoed a bill to legalize medical marijuana in New Hampshire. The bill originally passed the House and Senate with a veto-proof majority. An override vote is planned for tomorrow. While the issue is being hashed out in the Granite State, a new study on legalized pot has gone viral online. the study -- which is still in the review process -- found that in states that have legalized medical marijuana, the number of traffic fatalities have been reduced by an average of nearly nine percent. To find out more, Word of Mouth intern Emma Ruddock spoke with Mark Anderson, professor of economics at Montana State University, and lead author of the study.
