I have only smoked for a about a year and I'd say it was daily for a good 5-6 months. I really regret it obviously why I'm sitting on this forum. I've been off pot for about 30 odd days and I seem to have a brain fog. I'm hoping this isn't permanent because it's really getting to me. If anybody has had any similar experience let me know because I've done my research and most of the studies on marijuana are inconclusive and get me no where.
