A group opposed to pot legalization unveiled proposals on Thursday for the U.S. government to ease restrictions on scientific research into marijuana’s potential as medicine, after three U.S. Senators this year introduced a bill that would require the federal government to recognize pot’s medical value and allow states to set their own medical cannabis policies.

With Washington state overhauling its medical marijuana law, Seattle Mayor Ed Murray says the city is planning to shutter dozens of dispensaries. Murray on Tuesday announced plans to require a new special business license for marijuana establishments, akin to those required for taxi operators and pawn shops.

While the domestic War on Drugs has been supported for nearly four decades by Michele Leonhart, it appears as though some of her misguided policies, mostly those rooted in Reagan’s anti-reefer regime, may finally come crashing down with the recent appointment of the new leader of the DEA.

Sen. Bernie Sanders (I-Vt.) said Tuesday that he supports the decriminalization of marijuana possession and the legalization of medical marijuana, and suggested that he’s also open to considering further reforms when it comes to recreational marijuana.

When Erik Christiansen started smoking pot, he became fascinated by the look of different marijuana strains. But the photographs of marijuana he saw didn’t capture the variety. So he went to the hardware store and picked up two lights and a cardboard box. “I didn’t even have a macro lens — I was shooting through a magnifying glass,” he says.

While researching into how cannabis interacts with other drugs in the brain, scientists inadvertently discovered why coffee and getting high go so well together. Caffeine reinforces the effects with THC, potentially making it more pleasurable and/or requiring less THC to achieve the same effect.

There has been a tremendous amount of enthusiasm for the reform of marijuana laws in the state of Texas over the past several weeks, but all hope has since been abandoned after the state legislature tossed several pieces of legislation into the garbage. As the deadline approached, it became readily apparent that the legislative gatekeeper was simply refusing to submit the bills to the full House for their consideration.

Legalization keeps rolling ahead. But because of years of government roadblocks on research, we don’t know nearly enough about the dangers of marijuana—or the benefits. This week’s TIME cover story examines how little we know about marijuana’s effects on our brains, even as cities and states around the United States are legalizing the drug.

Launching a business from scratch is tough, and the hardest part can be getting the cash together to make it happen. A number of ganjapreneurs have opted for crowdfunding their projects, with some finding more success than others.

Medical marijuana faced the next hurdle on its way to passage Tuesday as the Pennsylvania Senate considered a bill that would legalize the use of cannabis to treat some medical conditions. Legislation was expected to pass the Senate, which approved a similar measure last year, and it did so with a vote of 40-7, but may face a more difficult vote in the House, which failed to consider it before the end of last session.

Should marijuana businesses pay tax on gross profits or net profits? It sounds like a silly question. After all, virtually every business in every country pays tax on net profits, after expenses. But the topsy-turvy rules for marijuana seem to defy logic. And taxes are clearly a big topic these days.

“Marijuana has many useful uses,” Morgan Freeman says. “I have fibromyalgia pain in this arm, and the only thing that offers any relief is marijuana. They’re talking about kids who have grand mal seizures, and they’ve discovered that marijuana eases that down to where these children can have a life. That right there, to me, says, ‘Legalize it across the board!’”

Elon Musk’s new Powerwall battery allows the average, or not so average, household to affordably use energy storage to lower electric bills. The relatively low price, compact size and high efficiency also means renewable energy might be in store in the near future for cultivating cannabis. This battery could save even a small time grower $1,000 a year.

When news broke that Founders Fund, the proudly contrarian venture firm helmed by PayPal co-founder Peter Thiel, was going to invest a major $75 million in Privateer Holdings, a company focused on producing, distributing and educating consumers about legal marijuana, it opened the floodgates for other investors to barrel in.

Earlier this week, ResponsibleOhio, the organization currently collecting signatures to get their initiative to legalize marijuana on the ballot in the next presidential election, earned the support of the three largest labor unions in the state – a collective force that represents about 70,000 working class citizens all over Ohio.

Puerto Rico’s governor on Sunday signed an executive order to authorize the use of medical marijuana in the U.S. territory in an unexpected move following a lengthy public debate. Gov. Alejandro Garcia Padilla said the island’s health secretary has three months to issue a report detailing how the executive order will be implemented, the impact it will have and what future steps could be taken.

A few years ago, my neighbor Luke went to a bonfire party on a mountain just outside of Beijing. Three busloads of revelers came from the capital, he said, amply provisioned with alcohol and cannabis; a few had mushrooms or acid. But the fun didn’t last. “There was a mole,” he guessed. On the way back, police stopped the buses at a tollbooth.

What to do with the prisoners of a failed war? Since 2012, when voters in Colorado and Washington approved the tax and sale of recreational marijuana, the cognitive dissonance of America’s drug penalties has become even more absurd. Where we once incarcerated people for growing and selling “just a plant,” we’re now incarcerating people for growing and selling “just a plant” that tens of millions of people can grow and sell legally.

New York State has begun accepting applications for its medical marijuana licenses this week. Applicants can submit questions through May 5th and the Department of Health Services (DOH) must answer those questions by May 14th. The deadline for filing an application is May 29th. The nonrefundable application fee is $10,000 and the registration fee is $200,000.

Congressman Dana Rohrabacher (R-CA) has introduced a new bill which appears to target the same aims of the so-called “Rohrabacher-Farr Amendment,” which many advocates claimed would end federal raids in medical marijuana states when it passed by bipartisan vote last year.
