I accidentally got my hands on an ounce of JH yesterday and smoked with a few friends.
We were blasting happy and upbeat music and passing it around. Was most definitely a GREAT experience. Everyone was extremely happy and had a pleasant experience. Even people that were depressed before smoking JH instantly felt better.
This is an extremely great strain for curing depression, anxiety, and any sort of similar problems. I suggest playing some happy/upbeat music while smoking (Bob Marley works great).
