i dont think my weed has ever been laced mabye when i was a little kid getting street weed in middle school then id beleive it but i know for a fact that around the time it happend to me i wasnt eating good and wasnt well hydrated either that day .the weed was dank too i never smoke mids or schwag .. i do inhale my hit for too long so all that triggered my 'passin out' and my friends for the same reasons right after a cup of water or liquid would make us feel better .maybe yours was laced
