Welcome back to The Week in Weed, your Friday look at what’s happening in the world of legalized marijuana.

One of the problems with a new industry is coordinating supply and demand.  Maybe Oregon and California could work together to solve both their problems.

Oregon’s top federal prosecutor said the state has a “formidable” problem with marijuana overproduction that winds up on the black market.

California’s top cannabis regulator said the state deserves credit for a successful rollout of retail marijuana sales, but acknowledged that significant issues loom in the near future.

Another week, another bit of marijuana banking news, as Fourth Corner Credit Union will be able to serve the industry – but there’s a catch.

Fourth Corner Credit Union will be allowed to bank marijuana related business but has to stay away from dispensaries, Fed says.

Fourth Corner won’t serve dispensaries, focusing on ancillary businesses such as accountants and landlords.

And finally, a useful survey from The Cannabist.

It’s been a month since U.S. Attorney General Jeff Sessions rescinded the Cole Memo, Obama-era Department of Justice guidance on enforcement of federal law in states that legalized marijuana in some form.
