California has entered a potentially landmark legal fight against some of its own cities over one of the most basic questions in the nation's largest legal marijuana market: Where can you buy it?

Beverly Hills and 24 other local governments sued California regulators Friday to overturn a rule allowing home deliveries statewide, even into communities that banned commercial pot sales. Ultimately at issue is who is in charge: the state bureaucracy that oversees the market or local governments where pot is grown and sold.

The U.S. cannabis industry has been severely restricted in its ability to access banking services because of federal prohibition. Two Canadian bank heads say they too will steer clear of the sector until new laws are passed.

It’s indicative of the limitations facing U.S. pot companies even as their market values surge and they engage in large-scale M&A like Cresco Labs Inc.’s $820 million deal last week to acquire Origin House.

As more states make it legal to smoke marijuana, some government officials, researchers and others worry what that might mean for one of the country's biggest public health successes: curbing cigarette smoking.

Though there are notable differences in health research findings on tobacco and marijuana, the juxtaposition strikes some as jarring after generations of Americans have gotten the message that smoking endangers their health.

"We're trying to stop people from smoking all kinds of things. Why do you want to legalize marijuana?" a New York City councilman, Republican Peter Koo, asked at a recent city hearing about the state's potential legalization of so-called recreational pot use.

This week the Georgia General Assembly passed a bill that would create a system for patients to purchase medical marijuana in the state. The legislation is expected to be signed by Republican Gov. Brian Kemp whenever it hits his desk, according to his spokesman.

Under the current system, medical marijuana is legal in Georgia, but patients have no legal methods available in the state to purchase it. Current state law prohibits the selling, buying, or transporting of cannabis. The bill passed by the Assembly, HB 324, would license private companies and universities to grow medical marijuana to be processed into low-THC cannabis oil.

Legislation that will allow the interstate transport of hemp and a hemp-derived extract called CBD through Idaho — where it's illegal — has been introduced.

The House Ways and Means Committee on Wednesday introduced the bill that would allow the director of the Idaho State Police to issue permits for the interstate transport of hemp and CBD.

The Senate on Monday approved legislation involving hemp that caused some House members to withdraw their support because of the amendments done in the Senate.

Republican Rep. Judy Boyle says the House legislation legalized hemp, but the amendments by the Senate undid that.

New Jersey has halted training state police dogs to sniff out pot.

Attorney General Gurbir Grewal told lawmakers Wednesday that a pending proposal to legalize recreational marijuana led police to stop training them to detect the odour of burnt cannabis.

He says dogs already trained to detect the scent could be used in other settings where marijuana would be prohibited, such as jails and schools. He added that it’s possible to train the dogs to detect marijuana in the future if needed, but it’s impossible to “un-train” dogs who already recognize the odour.

Grewal spoke at an Assembly budget hearing after a lawmaker asked how police dogs would be affected if recreational weed becomes legal.
