USA — The Editorial Board of the New York Times calls for an end to cannabis prohibition

In a statement of 27 July entitled “Repeal Prohibition, Again” the Editorial Board of the New York Times calls for the legalization of cannabis. “It took 13 years for the United States to come to its senses and end Prohibition, 13 years in which people kept drinking, otherwise law-abiding citizens became criminals and crime syndicates arose and flourished," the statement says. "It has been more than 40 years since Congress passed the current ban on marijuana, inflicting great harm on society just to prohibit a substance far less dangerous than alcohol.

The federal government should repeal the ban on marijuana. We reached that conclusion after a great deal of discussion among the members of The Times’s Editorial Board, inspired by a rapidly growing movement among the states to reform marijuana laws. (…) There is honest debate among scientists about the health effects of marijuana, but we believe that the evidence is overwhelming that addiction and dependence are relatively minor problems, especially compared with alcohol and tobacco. Moderate use of marijuana does not appear to pose a risk for otherwise healthy adults. (…) Creating systems for regulating manufacture, sale and marketing will be complex. But those problems are solvable.”

Australia — Norfolk Island allows cultivation of cannabis for medicinal purposes

A Tasmanian company that applied to trial medicinal cannabis in the state has been given the go-ahead elsewhere. Like Tasmania, Norfolk Island has an historic past that struggles financially and depends on assistance from the Commonwealth. But as the island's Health Minister Robin Adams explained, it was keen to pull itself out of that mire. "We are open for investment, we are open for business on Norfolk Island," he said. Norfolk Island is a small island in the Pacific Ocean located between Australia, New Zealand and New Caledonia. The island is part of the Commonwealth of Australia, but it enjoys a large degree of self-governance.

"We see this as a great opportunity both for the economy of Norfolk Island whilst providing a much needed medical product for export," he said. The island's government has given Tasman Health Cannabinoids (THC) approval to grow medical cannabis. THC had wanted to conduct its trial in Tasmania, with the view to it becoming a multi-billion-dollar export industry. "The Health Minister on Norfolk Island Robin Adams has now given us a production licence to go ahead and progress to grow on Norfolk medical cannabinoids," said the chairman of THC, Dr Mal Washer.

Australia — Discussion on medical cannabis

A desperate mother, a dying child, the rigid law and one man's experimental drug. The medical cannabis debate in the Australian Capital Territory (ACT) found a name and a face as it was revealed a 2.5 year-old girl suffering from a rare genetic disorder in Sydney had been treated using small doses of cannabis oil supplied by a Canberra man. Sydney girl Abbey, and her mother, Cherie, have been left without access to the oil after Australian Federal Police raided the ACT home of a supplier who had contacted Chief Minister Katy Gallagher.

USA — Cannabis legalization did not increase use of the drug by adolescents

A rise of cannabis use among teenagers over the past 20 years has no significant tie to the legalization of cannabis for medical use in many states, according to a new research paper. Comparing surveys of cannabis use by adolescents conducted annually by the federal Centers for Disease Control and Prevention, researchers found the probability that a high schooler had used cannabis in the last 30 days was no more than 0.8 percent higher in states with medical cannabis laws compared to states that had not approved medical cannabis.

UK — No influence of legal status on cannabis use

Researchers investigated the effects of declassification of cannabis in the UK in 2004. They found no relevant increases in either cannabis consumption, consumption of other drugs, crime and other forms of risky behaviour.

Uruguay — Plans to legalize cannabis may be stopped

Uruguay's plan to create the world's first national, government-regulated marketplace for legal cannabis may be going up in smoke. Delays in implementing the plan are putting it at risk as polls point to opposition gains in October's election and say most Uruguayans oppose a legal cannabis marketplace. Opposition politicians have said they will seek to repeal or modify the legislation, which gives the national government power to oversee the production, sales and consumption of cannabis.

Science/Cells — Alcohol alters endocannabinoid signalling in the brain

According to a study conducted with brain slices ethanol down-regulates cannabinoid signalling and results in altered network activity in the prefrontal cortex, an important brain area.

Science/Animal — Celastrol exerts anti-inflammatory effects by the activation of CB2 receptors

Celastrol, a major active ingredient of Chinese medicinal herb Tripterygium wilfordii Hook. f. has exhibited a broad spectrum of pharmacological activities, including anti-inflammation, anti-cancer and immunosuppression. Animal research shows that it attenuates inflammatory and neuropathic pain mediated by cannabinoid receptor type 2.

Science/Animal — Inhibition of 2-AG degradation reduces nausea

Inhibiton of MAGL (monoacylglycerol lipase) which selectively elevates the endocannabinoid 2-AG has therapeutic potential in the treatment of acute nausea and vomiting as well as anticipatory nausea, according to a study with rats.

Science/Animal — Reaction of the endocannabinoid system on kainic acid induced seizures depends on age

Increased levels of endocannabinoids protect against kainic acid induced seizures. Research with rats shows that the endocannabinoids anandamide and palmitoylethanolamine significantly increased in the hippocampus of younger rats treated with kainic acid, while decreasing in adults. In contrast, the levels of 2-arachidonoylglycerol (2-AG) were higher in older compared to younger rats.

Studies with rats suggest that the endocannabinoid system may contribute to sexual motivation in female rats by specifically altering approach behaviour. For example, rats treated with anandamide made more visits to a male stimulus than non-treated rats.
