Let's be honest here, for those on the left, if David Miller was caught smoking crack you'd defend his actions at all costs simply because of his political affiliation. Now that Rob Ford does it, and you hated his guts since day one, you rail against him like he just raped and pillaged an entire African village.
Is Rob Ford a crack addict? He's way too fat to be a crack addict. Go to Hamilton and you'll see what a crack addict looks like, they're paper thin and scary to look at. One of the biggest signs of a crack addict is loss of appetite and extreme weight loss, Rob Ford looks like he has a very healthy appetite to me. He smoked it once and made a mistake, I doubt he'll ever do it again, but based on his obesity we can definitively conclude that he's not a crack addict.
