This doesn’t work for addicts who are stutterers who can’t cope with stuttering, to just go “low dopamine” would be a host of psychological problems if the person is addicted. Also can you elaborate or show evidence that dopamine is higher in individuals who stutter? I don’t even know what you are saying so if you could elaborate I’d be appreciative. In most peer reviewed articles I’ve seen they mention how the quality of life of a stutter is low.
