I disagree that OCD is any form of addiction. In it’s most basic stripped down form an addicts chosen substance is taken to boost / trigger the reward mechanism in the brain (dopamine receptors). OCD does not adhere to that same driver. People with OCD do not do it for a kick of dopamine, they don’t get a rush out of doing it. At no point is OCD a pleasant experience where as drugs and alcohol can be before it becomes an issue.
Yes, addiction can be obsessive and compulsive but is in no way similar or comparable to the actual disease of OCD. x
