Science/UK: New cannabis extract may be helpful in ulcerative colitis according to clinical study

Data of a clinical phase 2 study with a new cannabis extract of the British company GW Pharmaceuticals show promising signals of efficacy in patients with ulcerative colitis. The pilot trial was a 10-week double-blind, placebo controlled study of GWP42003 extract, which contains cannabidiol (CBD) as the primary cannabinoid, but also tetrahyrdocannabinol (THC) and other cannabinoids. The trial included 60 adult patients with ulcerative colitis who continued to have symptoms from the condition despite treatment with salicylates, and in some cases immunosuppressive therapy. GWP42003 was given as a twice daily oral capsule up to a maximum dose of 250mg twice daily.

During the early weeks of the study, more patients withdrew from the active treatment group than from the placebo treatment group so that the analysed group comprised only 17 patients on GWP42003 and 27 on placebo. Most of these withdrawals were due to minor THC-related adverse events such as dizziness. At the end of the study the physician assessed 82% of the patients in the GWP42003 group as having normal or mild disease, compared with 52% in the placebo group. 93% of the patients regarded their condition as “improved,” compared with 60% of the placebo group.

UK: Cost agency says Sativex not cost-effective for the threatment of multiple sclerosis
The cannabis extract Sativex developed by the British firm GW Pharmaceuticals for treating spasticity in multiple sclerosis has been rejected as not cost-effective in the company's home market.

The Netherlands: Court does not punish cannabis growers
A Dutch court has refused to punish two cannabis growers, criticising a government policy that criminalises the drug's production while allowing its sale in coffee shops. “The court finds the suspects guilty,” the court in Groningen said in its judgment, but “no punishment will be applied.” Judges found that the cultivation was done in the spirit of the law on soft drugs, namely “in the interests of public health and so as not to disturb public order.” The Groningen growers were always open with the police about their activities, always declared their cannabis income to the government and paid tax on it.
