developing a stronger stutter after drug usage

developing a stronger stutter after drug usage has this happened to anyone else? i feel crazy trying to see if this is something that can actually happen, since ive seen nothing when i google it. i used to use coke regularly when i was 18-20, and dropped it considerably this year. ive always had a small stutter that never impeded on conversations, but now it's gotten worse. i can only attribute it to using drugs while my brain is developing, because i can't see what else would have affected me, neurologically. (besides one concussion, but my stutter was there before it)
