I think the difference is that SI is a direct attack on and intent to harm the body. Most people use drinking or drugs as an escape (which SI also is for some) but most people are not directly intent on harming their bodies with the drugs and alcohol. Of course, they know the dangers and do it anyway, but the intent is different - escape but not necessarily bodily harm.

I think it scares people in part because we are doing things to our bodies that are meant to hurt, that leave scars, and it is hard to comprehend what could possibly motivate someone to do this.

I don't know...just my two cents. I mean no offense to anyone.
