From my POV ive had similar experiences with all sorts of intoxicants. Which in practice is that they just increase the mood I’m currently in. Both from a stuttering POV and an anxiety POV and a general mood POV. But I do feel I care less about my stuttering when high and also since my otherwise insanely fast talking pace slows down to a more normal/slow pace which helps me choose my words better to avoid specific words/sounds I’m struggling with that particular day, which makes my stutter appear to be ”not as bad” when I’m high but in reality I’m just better at managing it and choosing my words more suitably.
