I found it useful? How was I to know you were a marijuana smoker?
I can easily presume that your speech impediment is caused by anxiety, which you just mentioned you have. That, combined with the fact that you care what people think, lets me know that you have no physical problems with your speech. Your problem is a neurological (which is what stuttering boils down to) insecurity.
You don't need to learn to speak properly, you simply need to practice speaking in front of people, and over coming your fear of what people are saying.
Marijuana slows your perception, yet seems to heighten your senses. If it helps with your anxiety, I'm sure it will help with your speech problem. And so what if it's short term? Enough smoke and your voice will become hoarse. And yes, it does affect the speech center, that's why you talk, and respond slower when you're high.
Enough time, and work, and it will correct itself.
(This post was every bit as helpful as my previous post, you'll simply think it was less spammy because it was longer, resulting in you thanking me, or appreciating what I've said more than you did priorly. Though I did not elaborate on what I said, it was every bit as helpful as this post.)
