I've had a very bad trip using weed. It was a horrible experience, my head was spinning and everything is dizzy, i've had bad trips b4, but nothing like this one. I thought i was going to die. My friends said i was as white as a ghost it was a very scary experience that would def. cause a newby smoker to never do it again. Also i was with my friend during lunch and i had some chubbaca with my vap, and he freaked out and has vowed never to smoke again. The dif. between a bad weed trip and acid trip is that the bad weed trip will only last like 20 min and u'll forget about it a week later.
