Back in 1974 my brother stoped stuttering for a few days. I’m (65M). My brother is 68. When we were teenagers in 1974 we had a habit of smoking marijuana and also took some other drugs. During a party one night a friend gave my brother some LSD. (WHITE MICRODOT). Anyway for the next few days he completely lost his stutter. I’m pretty sure he was as surprised as I was. Of course I wouldn’t recommend taking LSD or other psychedelic drugs as a treatment for stuttering but it seems like a valid question in my mind considering what I witnessed. Is it possible that micro-dosing Psilocybin could help with stuttering? Let me know if I’m out of line or should post somewhere else. I’ll answer any questions if there are any.
