You were just buggin out. It happens... You probably took a bong rip of some decent weed and got jacked up. Its better to sort of ease into Weed or any drug. The first time I smoked, it was a cigarette size joint with 4 friends. I got a nice high, but not smashed. You do need to be in good company, with people you trust and a familiar setting. It makes for a much more enjoyable high.
