Edit: Nevermind misread the qustion at first.
No. I'd stick with the rule of thumb that if a spell doesn't say it does damage, it doesn't do damage. If you do allow it, then you have to decide what the damage is, does it scale, is there a cap, can it impose a condition like dismembered, can a knife be 'stuck in an arm' or does it come out.... a can of worms easilly avoided. A DM however may allow it to happen if it makes the story more intersting or memorable, but no reason why he would be obligated to by the rules.
More Spam anyone?
