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)

How long does cannabis impairment last? Researchers are starting to find out
If rules about cannabis consumption for Canadian police are any measure, we know precious little about how long cannabis impairment lasts. The wait time for police to show up for work after consumption ranges anywhere from the next day to 28 days, with some forces prohibiting members from using the drug altogether.
University of Alberta psychiatrist Scot Purdon agrees the science is scant on impairment beyond the first few hours. (medicalxpress.com, USA, 18.10.2018)

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.

Editorial: Watching Canada’s experiment with legal cannabis
Diane Kelsall
CMAJ October 15, 2018 190 (41) E1218; DOI: https://doi.org/10.1503/cmaj.181287
On Oct. 17, 2018, the government of Canada will launch a national, uncontrolled experiment in which the profits of cannabis producers and tax revenues are squarely pitched against the health of Canadians. When Bill C-45 comes into force in mid-October, access to recreational marijuana will be legal 1 making Canada one of a handful of countries to legalize recreational use of the drug. Given the known and unknown health hazards of cannabis,2,3 any increase in use of recreational cannabis after legalization, whether by adults or youth, should be viewed as a failure of this legislation. The government of Canada should commit to amending the act if cannabis use rises.

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)
