okay i was at one of my boys house yesterday and the funnest thing happen. he said he got bud from a friend cheap and it was wicked purple. he asked me to go over and smoke with him so i did. i got there and looked at the bud and it wasnt purple it had mold all over it. come to find out he is color blind ive known the guy for 5 years and he has never told me. ok this is the funny part i told him i wasnt gonna smoke it he said he didnt care and preceded to smoke it. next thing you know he is coughing his lungs out then all a sudden crippled over in pain said his back hurt. he went to the hospital last night they told him he blew out one of his lower disks in his back. has anyone ever heard of that happening from coughing? i couldnt help but laugh i told the guy not to smoke it.
