I noticed my speech is perfect when I do coke

I noticed my speech is perfect when I do coke Before I start yes I know coke is bad and i do not recommend it to anyone, I just do it recreationally. I suffered from cluttering and a mild version on stuttering. I have taken years of speech therapy and it has helped tremendously. My speech also improved when I got medicated for ADHD. I was able to articulate my thoughts better and speak with fewer impediments. I noticed that when I do coke my speech is near perfect. The flow is smooth, no stuttering/cluttering, and Im not even overthinking of what Im saying, it just comes out smoothly. This is something that my friends have pointed out too. At first I thought I was being delusional then I decided to record myself and I was shocked how articulate and fluid I sound. Coke is know to cause rambling, hyperactivity, etc but I tend to go get the opposite when it comes to my speech. It just clears my head and my speech impediments. How come this is the case?
