Kanada. Canadian Cannabis Research Database

The Canadian Cannabis Research Database is an online tool that allows individuals to search current and ongoing cannabis research activities underway in Canada. Research since 2015 is covered under 40 possible topics.

The database is intended for researchers, healthcare providers and individuals involved in public health policy. It enables them to search research projects related to the health and social impacts of cannabis, while also fostering communication and collaboration between researchers and identifying potential gaps in cannabis research.

Cannabis - A field in flux. 

Fifty years ago, cannabis was known as the drug most emblematic of counterculture. Today, many people promote it as a fount of treatments for almost any ailment imaginable. This immense about-turn is reflected in changes in legal regimes: medicinal use of cannabis is now permitted in many countries, and some also allow the drug to be used recreationally. The times, they have a-changed. (Nature Outlook, 28.08.2019)

EMCDDA. New EMCDDA report highlights greater diversity of cannabis products, increasing potency and the need for close monitoring of health effects 

Cannabis products have become increasingly diverse in Europe and close monitoring of their potency and potential health effects is essential. These are among the conclusions of a new report published today by the EU drugs agency (EMCDDA) ahead of International day against drug abuse and illicit trafficking (26 June) (1). The report — Developments in the European cannabis market (2) — provides an overview of emerging and established cannabis products in Europe. (EMCDDA, Lissabon  25.06.2019 (News release No 5/2019))

Gen des Nikotinrezeptors schützt vor Cannabisabhängigkeit

Aarhus – Menschen mit einer Genvariante im Nikotinrezeptor sind weniger anfällig für eine Cannabis-Abhängigkeit. Dies kam in einer genomweiten Assoziationsstudie in Nature Neuroscience heraus (2019; doi: 10.1038/s41593-019-0416-1). (aerzteblatt.de,20.06.2019)


Chinese tombs yield earliest evidence of cannabis use

Researchers have uncovered the earliest known evidence of cannabis use, from tombs in western China.

The study suggests cannabis was being smoked at least 2,500 years ago, and that it may have been associated with ritual or religious activities. (BBC, 13.06.2019)

CBD kann die Wirkung von THC verstärken

Bislang nahm man an, dass der Cannabisbestandteil Cannabidiol (CBD) keine psychoaktive Wirkung hat und den Effekt des Wirkstoffs THC abmildert. Einer experimentellen Studie zufolge müssen beide Annahmen korrigiert werden. (drugcom.de, 06.03.2019)


Cannabisrauchen in Maßen könnte sich auf Spermien auswirken

Boston – Ein geringer Cannabiskonsum könnte sowohl eine höhere Spermienzahl zufolge haben als auch höhere Testosteronwerte. Das ergab eine Beobachtungsstudie mit fast 700 Männern, die in Human Reproduction veröffentlicht wurde (2019; doi: 10.1093/humrep/dez002). Einen kausalen Zusammenhang konnten die Studienautoren allerdings nicht nachweisen. (aerzteblatt.de, 07.02.2019)

Observations: Is Cannabis Good or Bad for Mental Health? The evidence says it can go either way.

(...) The reality is that cannabis cannot be pigeonholed as strictly helpful or harmful. Instead, meaningful discussion about its potential benefits and harms requires careful and nuanced consideration of the scientific literature, coupled with a humble attitude. As delineated in a recent and thorough review paper in the International Review of Psychiatry,the relationship between cannabis and mental health is especially complicated.

WHO: Die Übersicht zu Cannabis bleibt unter Verschluss 

Die mit Spannung für den 7. Dezember erwartete Veröffentlichung der Ergebnisse der zweijährigen wissenschaftlichen Bewertung von Cannabis, das „Critical Review on Cannabis“, im Rahmen des CND-Treffens (Commission on Narcotic Drugs) in Wien, fand nicht statt. Die letzte Einschätzung der WHO aus dem Jahr 1954 hatte das weltweite Verbot im Rahmen des UNO-Drogenkontrollvertrags gestärkt.

Als es an der Zeit war, die Ergebnisse im überfüllten Saal zugänglich zu machen, waren alle verblüfft, zu erleben, wie der Sprecher der WHO bekannt gab, dass das Ergebnis zu Cannabis vertraulich bleibt, und nicht einmal einen weiteren Termin für die Veröffentlichung nannte. Sprecher von Nicht-Regierungs-Organisationen kritisierten, dass die WHO sich nicht an ihre eigenen Regeln und Richtlinien halte. (IACM, 22.12.2018)
