I don't think anything could compare to the first time. Smoked 5 bowls thinking it wouldnt do shit (I had weed a couple of times before that and it did nothing), got so fucked, freaked out, cant remember ever losing control like that. Awhile ago I came off a month break, smoked a few bowls of some awesome weed sprinkled with speed (apparently), was very fucked but wont match the first time, the surprise factor plays a big part in your first time high.
