Any number of recent developments, beyond the increased interest reform advocates are getting, which I wrote about some time ago, suggest that marijuana legalization is beginning to get serious attention as an option. Anderson Cooper is doing a whole week of segments, and in this one Sanjay Gupta shows evidence of actually having learned something since since previous on-air discussion on the topic. And now Barney Frank has introduced a bill to legalize possession of 3.5 ounces or less -- less market-friendly than I might like, but a huge advance over prohibition. The Rhode Island legislature has overridden a gubernatorial veto to allow medical marijuana dispensaries or "compassion centers." 67-0 in the House and 35-3 in the Senate.
