What Causes Blurred Vision And Vomiting After Drinking A Bear?

so saturday night i was with a friend and that friend gave me a tiny bit of a weed gummy bear.. i ingested this gummy bear and then went to a&w for a little burger.. about an hour after i had already ate and the high started.. i was fine and then shortly after i start feeling really weird.. it progresses to the point where my vision went blurry, i threw up about 3 times, my body was shaking, it was very hard for me to breath, i didn t know where i was or how i got there, i started having hallucinations of things that weren t actually happening, my pupils were fully dilated and that actually lasted till later the next day but i still feeling really crappy.. my body are still having chills and i don t feel like throwing up but not myself. i have smoked pot before and i have never felt this way.. should i be worried? was it laced with something?
