Hmmm...The truth is that this is a muc more difficult addiction to address in a lot of ways - most people are not going to end up in the hospital because of a lust addiction (as opposed to an alcohol addiction). It's much more difficult for outsiders to see the problem.
One difference, though, is that for alcohol, a little drinking is fine - it only becomes a problem when it's an addiction.
With these issues, though, even for those who DON'T have an addiction (or don't know it, or haven't gotten there yet), it's still an area that they should be working on.
I've read in the chizuk emails about the rebbe who's working with his students in this area.
I wonder if there couldn't be some kind of program for helping teenagers, or even people older, deal with this issue, maybe even before it becomes an addiction, or before the addiction gets as far as it can.
