i find that the enviroment you smoke in your personality determine a lot how much you enjoy mj. my heart used to feel like it was beating a million miles per hour and id think i was gonna die but if you take your pulse your heart isnt going so fast. I just get really stupid when I smoke, like retard stupid but put an instrument in my hands and i just go to town. for some reason all music just makes sense to me when im stoned.
