The Netherlands — Lower house of parliament passed bill, which allows cultivation of cannabis

The Dutch lower house of parliament on 21 February by 77-72 passed a bill to decriminalize cultivation of cannabis in the Netherlands. The bill has still to be passed by the senate. Cannabis is available in "coffeeshops" for personal use but the actual production of the plant to supply those shops is illegal. As a result, retailers must open themselves to potential prosecution by growing their own cannabis or buying it from criminal networks.

Germany — Presentation of cannabis agency

On 3 March the Federal Health Ministry presented detailed plans for the new cannabis agency to oversee the cultivation of cannabis and the subsequent production to be used medicinally, in line with a new law approved by the Bundestag in January and is expected to take effect mid-March 2017.

Science/Human — Cannabis use not associated with higher risk of cardiovascular diseases

In a study with 5113 adults aged 18 to 30 years at baseline (1985-1986) from the Coronary Artery Risk Development in Young Adults study, who were followed for more than 25 years, cannabis was not associated with an increased risk for cardiovascular events. Compared with no cannabis use, cumulative lifetime and recent cannabis use showed no association with incident cardiovascular diseases, stroke, coronary heart disease, or mortality from cardiovascular diseases.

Denmark — More than 80% support the use of cannabis for medicinal purposes

More than 80% of Danes are in favour of legalising the medical use of cannabis, a new survey has found, increasing the chance that a pilot scheme planned for next year will lead to an end to prohibition. Denmark plans from January 1 next year to launch a four-year trial which will allow “a defined patient group” to be treated with medical cannabis, after an agreement was reached in the Danish Parliament last November.

Science/Human — Prolonged withdrawal symptoms in young cannabis users with psychiatric diseases

In 50 young adults, aged 18-25 years, withdrawal symptoms after cessation of cannabis use depended on psychiatric illnesses. Those without psychiatric diagnosis had significantly reduced withdrawal symptom severity in the first abstinent week and had shorter duration of cannabis withdrawal.

Science/Animal — CBD improved cognition in a rat model of schizophrenia

Using a rat model of schizophrenia, researchers examined the effect of chronic CBD treatment on cognition and social interaction. CBD treatment significantly improved recognition, working memory and social interaction deficits in this model. Authors wrote that “these novel findings present interesting implications for potential use of CBD in treating the cognitive deficits and social withdrawal of schizophrenia.”

Science/Human — High academic ability reduced the risk of tobacco smoking but increased the risk of cannabis use in adolescents

In a study with 6059 children, who were followed from age 11 to age 20, high academic ability at age 11 was associated with a reduced risk of cigarette smoking but an increased risk of drinking alcohol regularly and cannabis use. These associations persisted into early adulthood.

Science/Animal — Dose-dependent influence of THC on glucose uptake in the brain

THC influenced glucose uptake in the brain of rats. Low blood THC levels of < 1 ng/ml corresponded to an increased glucose uptake (6-30 %), while blood THC levels > 10 ng/ml coincided with a decreased glucose uptake (-2 to -22 %). There were differences between different brain regions.

Science/Human — No association between cannabis use and depression

In a longitudinal study with 2,348 patients with major depressive disorders level of cannabis use was associated with significantly more depressive symptoms at follow-up. However, after adjusting for baseline confounding factors, no associations were found between cannabis use and suicidality, functionality and quality of life. Authors concluded “that many of the associations between cannabis use and a more severe course of major depressive disorders do not seem to be attributed to cannabis use itself but to associated sociodemographic and clinical factors.”
