For me, this was not true. I smoked weed almost daily from my freshman year in high school through college. I was able to zone in and concentrate while high, and every subject was much more fascinating. It did take me longer to do the work but I pulled straight A's and was probably more creative and more willing to take calculated risks. I was probably the exception though because most of my stoner friends did not have this experience.
