In my subjective experience, weed-induced brain fog goes away after about three days of abstinence. This is after heavy duty multiple times per day for months at a time levels of smoking. Cravings also go away after about three days. I don't smoke weed any more though because it tends to turn into the aforementioned balls to the wall smoking pattern every single time I pick it up. I've never had that issue with any other substance.
