There is a neuro-scientist who’s research is proving that stuttering is a neurological condition. He believes it’s treatable through medication and mentions the positive effects of psychoactive substances such as psychedelics. Check him out on YouTube at ‘Dr Gerald Maguire’. He is the department head of neuroscience at Cal State, Fullerton Medical school and totally reputable. He’s also a stutterer. The drug he’s investigating is now in phase 3 trials and I’m in contact with a subject whose life has completely been changed since he’s fluent. Best, Sue
