After a debate pitting compassion for those suffering from the pain of cancer or HIV-AIDS against concerns about abuse and violence from expanded availability of a "gateway drug," the Minnesota Senate gave tentative approval Wednesday to the use of marijuana for medical purposes in the state.

The 36-28 vote came despite questions about whether the measure fully defines who would be eligible and whether it provides proper safeguards against potential abuse. [Star-Tribune]

The bill could still get blocked in the House and a veto from Gov. Pawlenty is a definite possibility. If you're in Minnesota, click here to contact your legislators in support of medical marijuana.
