weed and stuttering

weed and stuttering is it only me but i noticed when i smoke weed for a few consecutive days or if i smoke weed heavily, my stuttering gets worse later when im sober. I noticed that last year when i was smoking regularly my stuttering was very bad, i haven't stuttered like that since i moved abroad 5 years ago (used to stutter very bad when i was a kid, couldn't speak at all, but it improved when i moved abroad). Now i speak better but it still gets bad if i smoke weed
