Well, to sum up my feelings, I think that globally the "legalisation front have gained in power of credibility" as the very old receipes are too big too be taken seriously.
Officially no one dare to say it, but the Global Commission on Drug Policy report has made its effect, and the current dynamic in South and Central America give more power to the trend for reform at country or regional levels.
Like Drug Reporter (see link below) analysed it : after 100 years of US worldwide leadership, now the new imperialistic antidrug kingpin is Russia (remember that in 1961 at the shape of nuclear crisis US and USSR were totally friends with French and other to implement the current non-scientific drug narcotics schedule).
