i get frames only when im super-blazed. i got it a couple of weeks ago mildly and its the first time ive had it in a while. i think its deffinitly an effect that you only get from sativa (and salvia, but thats a different story). the first time i ever got frames was when me and my friends had some of this srgaight killa like a half oz or something and we kept taking these insane gravity hits all day. then we sat down and were playing halo and the frames hit me and i was like "shit, i cant play halo anymore". but other than that, it was one of my most intense experiences ever.
