Happy cake day! Not really. I’ve tried acid and shrooms more than once and I haven’t noticed a significant long term effect on my stutter. I can stutter less during the first day or two after a trip, but that’s more from being less stressed because of the trip. The only direct chemical way I have seen my stutter almost completely disappear is whenever I take adderall. I have ADD and I’m pretty sure it’s what causes my stutter, so it always made sense to me that taking adderall also helps my stutter. Edit: Haven’t tried DMT yet, but I’m keen to see if it’ll do anything.
