IACM-Bulletin of December 5, 2021
🌐 World — Over 180 civil society groups call for greater transparency at the INCB within its cannabis initiative
One year on from the formal recognition of the potential for cannabis as a medicine by the United Nations 181 NGOs, among them the IACM, call for greater transparency and accountability in the INCB (International Narcotics Control Board) , particularly in relation to its Cannabis Control Initiative. On 2 December 2020 the United Nations Commission on Narcotic Drugs (CND) rescheduled cannabis recognising its medical properties for the first time.
However INCB, a body of the United Nations, has launched its own ‘Cannabis Control Initiative’. In an Open Letter to the United Nations Secretary-General, António Guterres the civil society groups from 56 countries ask:
- Disclose INCB documentation like other similar UN bodies;
- Opt-in to the UN online documentation access and archival system;
- Extend the civil society consultations to all areas of work of the Board;
- Call for and collect written contributions from non-State actors;
- Allow NGOs & non-State actors to participate as observers in INCB meetings;
- Scale-up “country visits,” inspired in the human rights treaty bodies Annual Review Mechanism.
🌐 Switzerland — Pharmacies sell cannabis to adults
In Switzerland, the dispensing of cannabis for recreational use will be tested in several model projects in pharmacies starting 2022. Already from the beginning of next year, consumers in Zurich, Basel and other cities will be able to purchase cannabis in pharmacies and social clubs. The Commission for Social Security and Health of the Council of States - the small chamber of the Swiss parliament - had already laid the legal foundation for this in August 2020 with the so-called experimental article and enabled strictly regulated scientific studies on the use of cannabis.
Pilot trials are to be conducted to investigate the effects of regulated access to cannabis on consumption, health and purchasing behaviour. In this way, they are to provide "a factual basis for a discussion on the further development of cannabis policy and Swiss drug policy", as announced by the City of Zurich.

🌐 Malta — The country is the first in Europe to legalise home growing of cannabis for personal use
Malta is to legalize cannabis. Its citizens will be able to grow cannabis at home and establish cannabis social clubs. The bill also allows growing up to four cannabis plants at home. However, plants shouldn’t be visible from other places. When cultivating cannabis plants at home, consumers can keep up to 50 grams of dried cannabis in the household. Cannabis consumption in public will be forbidden unless the person is authorized to use it for medical reasons.
The cannabis reform bill has now to pass in parliament for the third reading and final vote. It is expected to become law in mid-December 2021. The legalization process started this year, when the Ministry for equality, research and innovation of the smallest country in the European Union introduced in October 2021 a bill to reform law on cannabis.
🏷️ Science/Human — The medical use of cannabis is associated with reduced opioid and benzodiazepines prescriptions in orthopaedic pain patients
In an prospective observational study by investigators at Legacy Research Institute in Portland, USA,
orthopedic pain patients profited from a treatment with cannabis. They were enrolled in Pennsylvania's medical cannabis program by their treating pain management physician, received cannabis education from their physician at the time of certification, and purchased products from state-licensed cannabis retailers.
Cannabis use was associated with clinical improvements in pain, function, and quality of life with reductions in prescription drug use. 73% either ceased or decreased opioid consumption and 31% discontinued benzodiazepines. Significant clinical benefits of cannabis occurred within 3 months of initiating cannabis therapy and plateaued at the subsequent follow-ups.

🏷️ Science/Human — Patients with psychotic disorders may need lower doses of neuroleptics if they get an additional treatment with CBD cigarettes
According to a small placebo-controlled trial with 31 acutely psychotic patients by investigators of the University Psychiatric Clinics Basel, Switzerland, participants needed lower doses of neuroleptics if they got an additional treatment with CBD cigarettes. CBD-rich cannabis with less than 1% THC was given in addition to standard psychiatric treatment. Outcomes were assessed after 4 weeks of acute treatment and long-term follow-up after discontinuation of CBD-cigarettes after 25 weeks.
There were no significant differences between the placebo group and the CBD group with regard to symptom severity. However, patients in the placebo group needed higher doses of neuroleptics. Authors concluded that “the presented findings might suggest an antipsychotic medication sparing effect of CBD-cigarettes as adjunctive treatment of acute psychosis. However, the low number of participants did not allow for further statistical analysis.”

🏷️ Science/Human — Cannabis may be helpful in paediatric palliative care
According to a case series of 6 children presented by investigators of the Pediatric Pain and Palliative Care Service of the Department of Women's and Children's Health at the University Hospital in Padova, Italy, a cannabis extract may improve pain and epilepsy in palliative care. Caregivers reported changes in intensity and frequency of pain and epilepsy events. The participants received a titrated plant extract of cannabis for 1 year.
Only mild and transient adverse events occurred: drowsiness, euphoria, restlessness and tachycardia; the resolution was either spontaneous or obtained by modifying the administration schedule. Treatment was never discontinued. All patients experienced seizures during the pre-treatment observation period, and obtained a reduction in seizure frequency, although with variable extent while receiving cannabis. In addition, a benefit on pain was observed, based on the caregiver's evaluation, and a reduction of analgesic use.

🏷️ Science/Human — An inhibitor of endocannabinoid degradation improved symptoms of Tourette Syndrome in clinical study
In a placebo-controlled study with 20 adults patients with Tourette syndrome administration of Lu AG06466, a selective inhibitor of the degradation of the endocannabinoid 2-AG (2-arachidonoylglycerol), was associated with symptom improvement. Participants were on standard-of-care medications and randomized to a single fasted dose of Lu AG06466 (40 mg) or placebo in period 1, followed by the other treatment in period 2.
There was an overall trend of tic reduction, with two out of three tic scales showing a significant effect at various time points. In addition, the study medication resulted in a significant reduction in premonitory urges versus placebo. The treatment was well-tolerated, and the most common adverse events were headache, somnolence, and fatigue.
