Colorado's efforts to ease regulations against the drug lead to a different type of discussion with dental patients who use it.

The headlines were splashed across all national media. Governor John Hickenlooper signed an executive order that makes an "official declaration of the vote" related to Amendment 64. That declaration formalizes the amendment as part of the state constitution, and makes legal the personal use, possession, and limited home-growing of marijuana under Colorado law for adults 21 years of age and older.

In December of last year, Nebraska and Oklahoma (the “NO States”) filed suit against Colorado in the United States Supreme Court, seeking to invalidate Colorado’s recreational cannabis laws. Last week, the Supreme Court invited the Obama Administration to weigh in with its position on the lawsuit.

Oklahoma and Nebraska want to rollback Colorado’s legalization of pot, calling it a “cross-border nuisance.”

Here’s a round-up of Monday’s Supreme Court developments.

Justices ask White House to comment on marijuana case: The Supreme Court asked the Obama administration to weigh in on a lawsuit brought by two states seeking to rollback marijuana legalization in Colorado, reports WSJ’s Jess Bravin:

Oklahoma and Nebraska asked the Supreme Court to invalidate laws implementing a 2012 voter initiative approved by their neighbor state, which legalized recreational use of marijuana.

Oklahoma took a small, first step Thursday toward legalizing one form of medical marijuana after Gov. Mary Fallin signed a bill that would allow medical trials of a cannabis derivative known as cannabidiol, or CBD, to move forward. Many say CBD is beneficial in treating children with debilitating seizure conditions. While Fallin, a Republican, made it clear that she remained opposed to legalizing marijuana outright, she said the bill would give researchers the opportunity to study the effects of CBD on children with epilepsy.

We know the end is coming, but pot prohibition is going to have to be undone state by state. Here are the ones least likely to jump on the bandwagon.

Marijuana prohibition in the US is dying, but it isn't going to vanish in one fell swoop. Even if Congress were to repeal federal pot prohibition, state laws criminalizing the plant and its users would still be in effect—at least in some states.

And it's probably a pretty safe bet that Congress isn’t going to act until a good number of states, maybe more than half, have already legalized it. That process is already underway and is likely to gather real momentum by the time election day 2016 is over.

Last year, The Weed Eater column debuted on 4/20 with a promise to take readers on “a cannabis-fueled culinary journey.” Since then, we’ve made a gourmet marijuana meal at Hunter S. Thompson’s house, sampled Melissa Etheridge’s weed-infused wine, brewed up some pot-fueled bulletproof coffee, explored the Joy of Cooking (while really stoned), concocted strain-specific cannabis cocktails, examined the Grateful Dead’s lasting influence on how we eat, and even shared a meal with Nonna Marijuana, the 92-year-old queen of cannabis cuisine. But perhaps, amid all the munchies and merriment, we’ve failed to make clear something vitally important: Marijuana edibles aren’t safe.

A year of debate, a slew of labeling regulations and multiple educational campaigns have not been effective in answering a critical question surrounding marijuana-infused edible products: How do you stop a consumer from eating too much?

Colorado Attorney General Cynthia H. Coffman announced Friday that the state will defend its legalization of marijuana for sale medicinally and recreationally against a lawsuit filed by the attorneys general of Nebraska and Oklahoma. Friday was the final day for Colorado to respond to the lawsuit, which alleged its voter-backed legalization initiative, Amendment 64, has sent a wave of uncontrolled cannabis across the two states’ borders since becoming law in 2012.

On February 28 some 75 tribal leaders from across the country met to discuss forming the first “Tribal Cannabis Association” at the Tulalip Resort Casino on the Tulalip Reservation in Washington State.

This followed a packed day on February 27 of “Tribal Marijuana Conference” presentations and panels with speakers as diverse as former U.S. Attorney Troy Eid (current chair of President Barack Obama’s National Indian Law and Order Commission) to the city attorneys of both Seattle and Boulder, Colorado, who gave in-depth overviews of how implementation of state laws legalizing marijuana possession and usage is proceeding in their respective cities.
