Many of the reasons above bust mostly because I'm addicted. I get high when I do it, I go through withdrawal when I don't, as soon as I'm done I'm thinking about when I'm going to get my next fix. I need to do it increasingly more to get the same high. I've spent a ton of money on it. I'm willing to risk my body for it. And to justify the addiction I keep trying to get others- even my family members- hooked also.
