Visitors to Colorado are turning up at the emergency room with marijuana-related issues in higher rates than people who live here, according to a study by the University of Colorado School of Medicine.

The study, which appears in the New England Journal of Medicine on Feb. 25, found that the number of marijuana-related emergency room visits to the University of Colorado Hospital doubled among those from out-of-state from 2013 to 2014, while remaining steady for residents.

The study can’t positively peg marijuana use as the cause of the visit, said Andrew Monte, assistant professor of emergency medicine and toxicology at the CU School of Medicine.

America is in the midst of a drug crisis—and the War on Drugs may be making it worse.

There were 47,000 deaths in 2014 as a result of opioid overdoses (or some 128 overdoses per day), according to data from the Centers for Disease Control and Prevention (CDC). That figure isn't just more than any other year on record; it marks a 200 percent increase in opioid overdose deaths since 2000.

VANCOUVER - Canada's marijuana confusion has become chaos.

The nation's medical cannabis scheme was found unconstitutional Wednesday by the Federal Court of Canada.

Federal Court Justice Michael Phelan said the Marihuana for Medical Purposes Regulations, which replaced the Medical Marihuana Access regulations in April 2014, violated the liberty and security interests of the charter.

He gave the government six months to fix the law.

"The access restrictions did not prove to reduce risk to health and safety or to improve access to marihuana — the purported objectives of the regulation," wrote Phelan, who heard evidence in the case last spring.

A federal court judge in Vancouver on Wednesday ruled that medical marijuana patients have the Constitutional right to grow their own cannabis, striking down a ban introduced by Canada's previous Conservative government.

The court suspended its decision for six months to give Ottawa time to respond.

A group of British Columbia residents took Canada to court in 2013, arguing a new law requiring medical marijuana patients to buy cannabis from licensed producers, instead of growing their own, was unconstitutional.

They said marijuana grown under the government system was too expensive and did not allow them to control the strains and dosages of their treatment.

We like to think of ourselves as leaders…

But this time we’ve fallen behind.

Australia became the first continent to legalize medical marijuana after the Australian Parliament passed a measure earlier today. The amendments to the Narcotic Drugs Act legalizes the cultivation of medical marijuana for medical and scientific purposes.

Following the passing of this amendment, the Australian Minister for Health Sussan Ley made the following statement:

A Federal Court judge has struck down federal regulations restricting the rights of medical marijuana patients to grow their own cannabis.

In the ruling issued on Wednesday morning in Vancouver, Judge Michael Phelan ordered the Marihauna for Medical Purposes Regulations has no force and effect, but suspended the declaration for six months so that the government can come up with new rules.

The judge also ordered the injunction that has allowed thousands of Canadians with an authorization to use medical marijuana to grow marijuana will remain in effect.

ADHD Hyperactivity, impulsiveness, mood swings, hypersensitivity, crankiness, lack of concentration and organisation, as well as difficulty falling asleep.

As more states legalize marijuana for medical use, the cannabis customer base has reached an older demographic.

Nearly 85% of medical marijuana patients had some form of higher education — nearly 15% held a postgraduate degree — and about 45% of patients were parents, according to a survey of 1,400 patients ages 18 to 80 — one of the largest patient surveys to date — by HelloMD, a digital health care platform that provides doctor consultations via live video chats for cannabis patients. Medical marijuana is legal in 23 states, while cannabis for recreational use is legal in four states and the District of Columbia.
