Ok, ive been smoking for like a year and i had never had this experience. I went to go chill and smoke with my friends down at the canyon. My friend had hooked me up with some shitty chronic so we went to go smoke it. I took about 10 hits from a glass pipe and at the end i packed a bowl and saw that there was some white stuff on the weed. It was like the weed color like it wouldnt come off if you tried to scrape it off. So i take my last hit and off i go and like 10 minutes later i start feeling really dizzy. A couple minutes later i was sitting down and everytime i closed my eyes i felt like a was flying and i could see all these types of patterns in my mind. I felt dizzy, nauseas, i felt like i couldnt walk i was stumbling and seeing like in frames almost slow motion. I took a cold shower and it helped a little but i just felt horrible. I was tripping out so hard and i thought i was gonna die. I felt like time was going soooo slow and every 10 minutes seemed like an hour. This lasted for about 5 hours after i started feeling better and hungry but what could have hapened, was the weed laced or is this a normal bad trip from smoking too much? i really dont remember much because everything felt like a dream. I couldnt write or concentrate on something and i felt like everything was melting around me. Really scary moments.
