I used to quite enjoy shrooms but I never really noticed it making my stutter better or worse but there's two psychedelics that every time I've taken my stutter disappears completely for the length of the high. LSA and 25I Nbome( Synthetic acid) I definitely don't recommend the Nbome but I guess everything is worth experiencing. Definitely worth experimenting with LSA and see what happens. :) I couldn't tell you how or why it affected me like that but yeah every single time, I'd say 10-15 times. Pretty interesting tbh.
