I kind of agree with Sadiq Khan here, but this is not anything like full #decriminalisation and I doubt it would reduce #crime levels that much - most stoners don't really do much crime (other than maybe #DUI ), its the hustle culture of low to medium level dealing that leads to bloodshed, and that could only be reduced by having tolerated and regulated distribution networks (you rarely hear of rival vape shop owners stabbing each other!)
