A brain circuit that helps create new memories to erase scary ones has been identified, at least in mice.

The circuit connects two brain regions associated with emotion and decision making, researchers said in a new study. Other studies have suggested that these brain circuits operate very similarly in both humans and rodents.

"It translates across species very effectively," said study co-author Andrew Holmes, a neuroscientist at the National Institute on Alcohol Abuse and Alcoholism and the National Institutes of Health. "Immediately, we've got an idea of what may be going awry in the human brain in those folks who experience [post-traumatic stress disorder] and anxiety."

CHICAGO — Medical and recreational marijuana might be on the brink of becoming big business for growers and dispensaries, but Rudy Medrano and his company, RM Global Security, see opportunity for the security and enforcement side of operations, too — so he's encouraging Chicago dispensers to shop local.

The news media will certainly focus a lot on marijuana in the 2016 election. Unless you have been living under a rock, you know that marijuana is covered a lot in the media these days.

But the state's medical board has just ruled not to recognize marijuana as a treatment for PTSD.

High There! a cannabis-sharing social network teamed up with Grow4Vets to host an impromptu rally on their Save a Million Vets Tour.

“Now we've created a tour around the country called the Save a Million Vets Tour," Co-founder and CEO of High There! Todd Mitchem said.

Veterans lined up early in Rino's Taxi district, most wearing their colors, letting folks know where they served.

Mitchem came up with the first social sharing network for cannabis users. Now he is partnering with Grow4Vets, helping vets get medication.

Minnesota Medical Solutions, one of the state’s two medical weed manufacturers, has jacked up prices by 15-20 percent on all its products, forcing chronically ill patients to head back to the streets to treat their pain.

Marijuana reform is a very popular political topic these days. I remember as recently as the beginning of this decade when supporting marijuana reform was considered to be political suicide. But more and more elected officials are getting on the right side of history every day it seems. Many local elected officials are particularly supportive of marijuana reform.

ANNAPOLIS, Md. (AP) -- The first specialty clinic for medical marijuana opened in Annapolis in June and has seen more than 100 prospective patients even though the Maryland Medical Cannabis Program isn't expected to be operational for another year.

Greenway Consultation, located in the Conte Lubrano Office Building, has three consultants and three physicians, who are not yet registered to recommend the drug through the Maryland Medical Cannibis Commission. The commission develops and oversees all licensing, registration, inspection and testing.

The clinic's spokesman Nick Petrucci said opening in advance of the program has advantages, such as beginning to build the patient-doctor relationship to expedite a recommendation for marijuana when the program begins.
