Wie wirken Cannabinoide auf lange Sicht? Das will offenbar die <a href=www.basqueresearch.com target=_blank>Uni im baskischen Leioa herausfinden: According to a research team at the Pharmacy Faculty at the Basque University at Leioa (Bizkaia) Campus, one of the keys to the problem presented by opiates and cannabinoids could lie in nitric oxide. Nitric oxide is a neurotransmisor found in the brain in gaseous form. According to the hypothesis, if nitric oxide inhibitors are supplied together with the opiates and cannabinoids, the therapeutic effect is maintained and, moreover, the dependence on and tolerance to the narcotic can be avoided.
