Different people take it differently. I lead a super active life, and am more active than my friends who don’t indulge.
I clean, do stuff, am active, and consume heroic amounts of weed. I wake up early AF and am always early to things. I am not forgetful either or act “confused”.
I know everybody is affected differently, yet I hold the belief that the “stoner stereotype” is not as much about the weed slowing people down but about people being themselves and using weed as an excuse.
Perhaps my belief is due to my experience with it.
