Why do people do crack cocaine when it makes you look like a homeless man?

Like it is so good for you?<br><br>Edit: wow this blew up quick<br><br>Edit2: I use to work at a grocery store and I had to move a rock we found in the trash and it smelled like death. I looked in a hole and there was a crack pipe so I assumed it was crack lol so it smells horrible like death
