I spoke to someone today about Xylocaine actually and they seemed to think that as much as you try to localize the effects of it, apparently it has slight pain killing effects all over the body.

If this were true, I'd question whether it should be allowed..But then again if you take a shot on the chin or temple, you can be on any kind of pain killer you want right? You would involuntarily be disorientated.

Then again, not sure if this is true so just food for thought more than anything
