I know I’m kind of late of this post but I’d like to share my experience with stuttering and the devils lettuce. I used to be a heavy stoner. I’m still a stoner, just not as heavy. When I first started smoking it was pure bliss. Everything was better. My mood, stutter, colors, music, sex, food, and pretty much everything else. However, like a year into this marijuana craze I noticed my stutter had worsen. In addition to this I also noticed that I started having bad anxiety. The combination of my worsening stutter and anxiety made my life a living hell. There’s more to the story but it would be too long. I suggest you limit smoking to nighttime and special occasions. This could possibly mitigate your marijuana induced stuttering.
