Which drugs should be demonized for Hegstrand’s death?

The Road Warriors, a professional wrestling tag team, were first that introduced bodybuilding-type muscularity in this sport. This tag team was composed of Hawk (Mike Hegstrand) and Animal (Joe Laurinaitis). Hegstrand died in 2003. The death of this wrestler came suddenly because of a heart attack. This wrestler died when he was just 46. It is known that popular media usually reports about deaths of professional wrestlers, connecting the cases with intake of anabolic steroids. The death of Hegstrand was not an exception. After the death of this wrestler numerous articles appeared in newspapers that blamed anabolic steroids for this case.
Joe “Animal” Laurinaitis admitted to administration of steroids by this professional wrestling team. But he pointed out that these products hadn’t caused Hegstrand’s death. He added that other conditions were responsible for Hegstrand’s death as well as deaths of other wrestlers. Joe Laurinaitis noted that such drugs, as cocaine and Xanax had to be demonized for such cases. Joe Laurinaitis announced that he wanted to explain that steroids had not been connected with Hegstrand’s death.
Joe Laurinaitis confirmed that cocaine and Xanax had led to Hegstrand’s death. He also noted that these drugs led to deaths of such individuals, as Henning, Rick Rude and Davey Boy Smith. According to Joe Laurinaitis, administration of cocaine frequently leads to administration of morphine. These drugs corrupt health wholly and lead to heart attacks.
Why must explanation of Laurinaitis be true? He was in Australia with Hegstrand. He knows about what he speaks. Recently Laurinaitis collaborated with Andrew William Wright to talk about his experiences with “Hawk”.
