>>8886747yeah this has happened to my friend. he took a 200mg hit to the face, and was out so fast he forgot to exhale for 45 seconds. then when he finally exhaled after being totally out of his body, he started throwing up on himself. i had to keep his head up and forward, after he came back I asked if he had taken anything else that day, and found out he had taken 3or4 xanax bars that day, I threw up this morning when i was smoking some spice in a joint, sometimes if your stomach is empty or you mix with other chemicals throwing up can happen. try taking dramamine prior to launching
