So long story short, all through last year, I used to smoke weed and drink coffee. It was habitual, like I would always have them together. In turn, I experienced the side effects of both things consumed - the alert, energetic feel from the coffee and the stoned, scatter-brained feel from the weed. Recently, I've been drinking coffee by itself, and I still have, though to a lesser extent, the stoned, scatter-brain feel. Has anyone had a similiar experience or know what's going on from a biological/psychological viewpoint?
