If I talk when I'm in my own it's fine but it's mainly in front off people when I start stuttering. I was researching and it says you can develop a stutter due to drugs but didn't say anything about cocaine. It did mention an amitriptymine which is an anti depressants I took for a fairly long time. I'm quite worried about going doctor but if it's still here in a couple days Ill go. I can see how sum drugs can cause issues like that but all it said about coke was it improves a stutter whilst on it.
