A.I. has an all-encompassing high that is so intense that it's not really safe to think about doing anything that could hurt you while you're smoking it. It's an intense mind and body high that mentally puts you in that beautiful thought provoking, mind expanded condition of invention. If you have pains, you won't notice them while high on this stuff.
Couch lock? Not really, unless the couch is where you choose to do your trippin. I love to take a couple of tokes and wander around town watching people and enjoying the air and day.
With no doubt what-so-ever, it's the most mind expanding MJ I've ever smoked. I've harvested it early, on time and late. It's awesome stuff no matter when you harvest. My favorite is at 50-50 cloudy/amber trichs. Like I said, one toke and you're off to join Alice in Wonderland.
