i would like to share my experience on 2cb. I had blown 35mgs of 2cb in less than 90mins. about 2 hours later i started feeling the mdma... so im feeling maad good and all and i smoke a nice fat blunt... 4 hits into it i start trippppiiiinnnnn... I was staring out the window and theres a school there next to some powerlines! they come to life and i had Infected mushrooms playing really really loud. so they started to dance with each other and the more i concentrate the more i tripped. I had full control of my vision, i was able to till my view left and right like a boat and completely upside down. i was also seeing in 2 different views. one eye was seeing maaad trrippy paterns and the other eyes saw everything melting.. it was insane! then it started coming down im like oh noeeee fuck that! i spark up the same blunt and take 4 more hits... triiipppppy laaaaand all over again!!! and this happen one more time after that. This has got to be the most best thing i ever messed with! *siiiigh* its very rare >.<
