The effect is pretty much immediate with a gummy. It's legal in my state so I got the standard gummies from the grocery store. I started taking them when work and life stuff was too stressful and I couldn't sleep. I did notice that it calmed me down in general and I was speaking much better. It's the opposite effect that alcohol does (for me). I took CBD for about 2-3 months when I was able to find a better job and move to a better position:). I still stutter of course but it's better when I am not anxious
