Damn. This sucks. I was trying to be optimistic before but now it's useless. Addiction to pain killers is not something to laugh about or bash him for. People get addicted to them all the time, and it's unfortunate that most people get addicted on accident just by having one or two prescriptions for a real problem.
Karo is still relatively young, and has a lot to learn. I hope he can get cleaned up, judo throw some fools in Strikeforce for a lil while, and maybe eventually get back to his full potential as a fighter. He's always been a favorite of mine and I wish him the best luck overcoming his addictions and anxiety issues as I can relate first hand to them. It's not fun.
