Yes. When u are addicted to a substance you suffer physical withdrawal symptoms. You may also have emotional and mental withdrawal but it's not a physical thing. When you act compulsively you want to do that thing for many mental emotional and varied reasons. Bumif you do not you will not get sick throw up or have any truly physical symptoms.
Treating compulsive symptoms is more like treating OCD than addictions. But I am coming from a therapeutic point of view not that of a laypersons. I feel that people use the word addictions in lieu of compulsions for many reasons but they are not the same.
I will answer more when I am not on my phone and on vacation. ;-)
