Chris Sullivan won the super bowl with Tom Brady and the New England Patriots, but he spiraled out of control. He started taking pain killers, after an injury.
Chris Sullivan said, "It's just such a small pill, you know, you're like what can this really do to me?"
Chris didn't think he had a drug problem, then a friend turned him on to heroin, and he was hooked. His $25,000 a month habit took over his life.
Doctor Wes Boyd says 10-percent of the population is true addicts; others don't use drugs at all. In between are recreational drug users and many might be considered almost addicted.
Boyd said, "Consider as seriously as possible exactly how you are using substances a how they make you feel."
The doctor tells us these people fall short of being diagnosed as addicts, but drugs can still hurt their health, daily lives, and relationships.
There's a chance, that like Chris, they could become full blown addicts. Here are some warning signs. Users can only relax in social settings when they're on drugs. They miss functions or obligations because they're high. Their careers suffer, and they have conflicts with co-workers, family, or friends.
Chris has been drug free since 2008, and hopes his experience will help stop other almost addicts, from crossing the line.
"You really got to pay attention, you know. I didn't. And it can happen to anyone," Chris said.
