Of course you do. It't the nanny government socialist in you peering out from behind the mask of libertarianism.
You are all for allowing pople to get stinking drunk or stoned and allowing others to pay for the consequences. Admit it: you prefer that devil over the devil of prohibition. Just be honest and admit it. That's all we ask of you nanny government pro-dope socialists--just a little bit of honesty.
People already pay consequences for others getting drunk or stoned. I don't have any problems with punishment for injuring others.
