Lebensgefährliche synthetische Cannabinoide bedrohen Bevölkerung

Berlin. Der Deutsche Hanfverband ruft Bundesgesundheitsminister Spahn dazu auf, die Gesundheit von Millionen Cannabiskonsumenten zu schützen. Es gibt in den Medien alarmierende Berichte über Menschen, die sich unwissentlich mit synthetischen Cannabinoiden vergiftet haben. Viele Erfahrungsberichte, die beim DHV eingehen, bestätigen das. Synthetische Cannabinoide, die bis zu hundert Mal stärker als das in Cannabis enthaltene THC wirken und ein höheres Abhängigkeitspotential besitzen, werden auf CBD-Hanf oder minderwertige Cannabisblüten aufgetragen und sorgen so für zum Teil tödlichen Vergiftungen. Sie bergen unkalkulierbare gesundheitliche Gefahren, da die Konsumenten annehmen, sie würden herkömmliches Cannabis und keine hochpotenten synthetischen Cannabinoide konsumieren. (DHV – Deutscher Hanfverband, 25.01.2021)

Cannabis use prompts need for more anesthesia during surgery, increases pain 

CHICAGO - Not only might cannabis users require more anesthesia during surgery than non-users, they may have increased pain afterwards and use higher doses of opioids while in the hospital, suggests first-of-its kind research being presented at the ANESTHESIOLOGY® 2020 annual meeting.
