A single paragraph 13 pages into the Regulation and Taxation of Marijuana Act, also known as Arizona's Prop 205, may create an insurmountable obstacle to prosecutors who are trying to convict people of driving under the influence of marijuana.

"This provision protects marijuana-using drivers unlike any other substance-using drivers within the state of Arizona," said Bill Montgomery, who is the Maricopa County Attorney and a vocal opponent of the initiative.

Denver voters will decide this November whether marijuana consumption should be allowed in bars and restaurants.

Just days after the rejection of a competing measure proposed by the Denver chapter of NORML, elections officials announced last week that the issue of social marijuana use would still go before voters this fall.

On Thursday, organizers with the Neighborhood-Supported Cannabis Consumption Pilot Program received confirmation from the Denver Elections Division that the group collected enough signatures to earn a spot in the upcoming election.

Hillary Clinton's husband has a famous history with marijuana. 

During his 1992 run for President, Bill Clinton said he had "experimented" with cannabis but "didn't inhale and never tried it again," he said, in a nod to the "just-say-no" culture of the time. 

That was four years before California would become the first state to legalize medical marijuana and two decades before Colorado and Washington legalized recreational weed. 

This year is very different. More than half of Americans want to see marijuana legalized. Patients in 25 states and the District of Columbia use marijuana for medical use. Four states allow possession and sale of marijuana. Five more may approve recreational use in November. 

Veterans and others in New Jersey can now legally treat their post-traumatic stress disorder with marijuana.

Republican Gov. Chris Christie signed a measure Wednesday allowing people to use marijuana if their PTSD isn’t treatable with conventional therapy. In a statement sent with the announcement of the bill signing, Christie noted that federal officials estimate up to 20 percent of veterans returning from combat in Iraq and Afghanistan have been diagnosed with PTSD.

But Christie also directed the state’s health commissioner to promulgate additional regulations that provide “clear objective criteria” regarding the drug’s use for PTSD. Christie has said he wants to make sure legalizing medical marijuana doesn’t become a backdoor into legalization for recreational use.

Cannabis should be made legal for medicinal purposes, say a cross-party group of U.K. MPs.

The All Party Parliamentary Group on Drug Policy Reform says that clear evidence from a seven-month study shows the drug can play a therapeutic role for individuals with certain conditions—including chronic pain and anxiety.

The influential Ontario Chamber of Commerce is urging Premier Kathleen Wynne to allow recreational marijuana to be sold by government-licensed private retailers as long as local municipalities approve.

In a letter being released Wednesday, the chamber’s president urges Wynne “to immediately begin a robust consultative process aimed at developing a regulatory framework for the distribution of recreational marijuana.”

At TechCrunch’s Disrupt SF event on Tuesday, U.S. Secretary of Defense Ash Carter said the military should be more flexible about hiring people who’ve previously used marijuana or other federally illegal drugs.

Arkansas Governor Asa Hutchinson, who is apparently still brainwashed from his days with the Drug Enforcement Administration, has been out in the public spewing hard core devotions of reefer madness in an attempt to persuade the voters to completely disregard a couple of medical marijuana initiatives when they head to the polls later this fall.

Standing alongside a panel of supposed medical professionals earlier this week at the State Capitol, Governor Hutchinson told reporters that he was not in favor of the medical marijuana ballot measures that are set to go before the voting public in November because neither one of them comes with the same federal safeguards that leads to effective medicine.

Governor Asa Hutchinson held a news conference Monday to detail his opposition to medical marijuana proposals going before voters this fall.

He plans to give $10,000 from his political action committee, called Asa Pac, to a group fighting against two medical marijuana proposals.

During the press conference, Governor Hutchinson was backed by doctors as he talked about his opposition to the Arkansas Medical Marijuana Amendment and the Arkansas Medical Cannabis Act.

Both ballot questions will be before voters in November.

In addition to concerns about regulation, cost to taxpayers, and violating federal law, Hutchinson disputes those who say the proposals will help suffering patients.

Debilitating diseases and chronic conditions severely impair the quality of life of patients; for those suffering from Crohn’s disease, or multiple sclerosis, or arthritis, or the aftereffects of chemotherapy, the ability to find relief from pain can make a real difference.

Fortunately, advances in medical technology are finding answers. An increasing number of people suffering from these conditions are finding that medical cannabis can make a difference that their prescription medicines simply cannot.
