Hmmm that is a tough one. I have never cut but I think of it as a form of addiction like from the relief the endorphins bring. It is not really an addiction in the traditional sense. A coping mechanism for sure but other addictions are coping mechanisms too.

I have been clean and sober for many years but I am still addicted to cigarettes. I could be addicted to these forums, or gaming which I was at one time in sobriety. In my using days I switched addictions all the time. Any drug as long as I liked the effects. Alcohol was my favorite.

In sobriety behavioural addictions become much easier to get and are more common. Work, relationships, running and working out..... Not as harmful but still addictions.

In your case I would think it would very much depend on if you really have an addictive personality. Maybe cutting was just a coping mechanism and not really an addiction in like you have very strong addictive tendencies. You may use alcohol as a coping mechanism and not be an alcoholic. Many people do who are not true alcoholics. What is your past experience with substance use?
