Welcome back to The Week in Weed, your weekly look at news concerning marijuana.  Massachusetts is debating the legalization of cannabis for recreational purposes, while Ohio is considering legalizing medical marijuana.  Colorado, meanwhile, is waiting for word on whether the lawsuit filed by its neighbors, Nebraska and Oklahoma, will be heard by the Supreme Court.

Supporters and foes of legalizing marijuana gathered at the Massachusetts Statehouse on Monday to weigh in on a proposal that would allow the recreational use and possession of marijuana up to an ounce for those 21 and older.

The group behind a new push to legalize medical marijuana in Ohio has submitted its first batch of signatures to state officials, paving the way toward a more significant spring and summer push.

The U.S. Supreme Court may finally be nearing a decision on whether to hear a case brought against Colorado by two neighboring states over marijuana legalization.  The states are arguing that cannabis from Colorado is turning up in their states, in violation of their anti-drug laws.
