I (33M) smoked weed everyday for a long time. I took breaks here and there, 6 months here, a few months there, and have just embarked on another break. I find the stronger the weed the longer it takes me to get a clear head and I tend to stutter more. HOWEVER, I'm unsure if that's the weed or lack of sleep as the strong stuff seems to dull my executive function and I don't go to bed when I should. If I were you I'd try to find some much lighter weed and make sure you're getting a good night's rest.
