A public hearing is planned this week on the possible legalization of marijuana in Vermont. The Wednesday hearing will be held statewide via Vermont Interactive Television. Earlier this year the Legislature ordered the administration to study marijuana legalization. A report is due in January. The state contracted with the RAND Corporation to examine issues that include production, distribution, and possession of marijuana. The hearing will be held by Secretary of Administration Jeb Spaulding and Beau Kilmer, the codirector of the RAND Drug Policy Research Center. Spaulding and Kilmer will make brief presentations, after which the session will be devoted to questions and comments from people attending the meeting.
