I really believe that we are on the right side of history – one day people will look back on global drug prohibition with the same sense of whimsy and incredulity that we look back on alcohol prohibition in the USA in the 1920s: “well, of course that didn’t work – what a stupid idea”! But until we get to that place, people are still being killed, still overdosing, still facing unacceptable harms and risks, still being demonised.
