I find it nearly impossible to even speak on weed, never mind fluently. I can’t drive, walk or even think with any semblance of clarity whatsoever on that stuff. People find that odd, because I’m anything but a novice when it comes to drugs. I can do meth, coke, crack, opiates, opioids or anything else considered a “hard” drug, and I can basically go about my day as I would if I were sober… but weed completely slays me, turning me into a non-communicative, drooling blob on the couch who just can’t seem to get enough to eat. That being said, none of the before-mentioned substances have a positive effect on my fluency. Oh, hell no… As the OP mentioned, alcohol can help a bit sometimes. Unfortunately, as an alcoholic on an eleven-year recovery streak, alcohol is no longer in my inventory of crutches.
