Recent evidence suggests that long-time steroid users and steroid abusers may experience the classic characteristics of addiction including cravings, difficulty in stopping steroid use and withdrawal symptoms. "Addiction is an extreme of dependency, which may be a psychological, if not physical, phenomena," says Dr. Wadler. "Regardless, there is no question that when regular steroid users stop taking the drug they get withdrawal pains and if they start up again the pain goes away. They have difficulties stopping use even though they know it's bad for them."
