Sadly, with what he has put his body through over the past decade plus has led him to the dependency on pain killers. Now he has had multiple chances in multiple organizations, but how many of them truly tried to get him help? I really don't know for certain, but what TNA needs to do this time is to check him into a rehab facility and basically tell him on no uncertain terms, clean up or don't come back, and stick by it.
I feel for Hardy and his family, hopefully he gets to help he needs before it's too late.
