Thanks for all the answers, even the serious ones, I've had a funny time reading all that.
Sooo... the conclusion is that there isn't a conclusion, right? I'll probably clean the pipe with alcohol and then wait until that part of its life gets erased from my memory. Then I suppose I'll be able to smoke in it without problem.
Thanks again!
PD: I'm selling a pipe on eBay, if anyone is interested...
