That's crazy. For me, its the opposite. Alcohol greatly improves my speech as long as I'm not too drunk. lol. It starts off by making it worse but once i have a little buzz going, I can speak pretty fluently. Weed on the other hand, makes my stutter severely worse. I get anxiety when I know I need to talk. But could that be because i only smoke Indica? That's mainly why I only smoke when I'm home and about to call it a night. MDMA practically takes it away. One my most fluent times in recent memory was when i was constantly on E. My good 'ol raver days. lol Do you find any difference in your speech when you smoke indica vs sativa?
