Clare Waismann quoted in Hollywood Life on May 3, 2013:
“Individually [heroin and cocaine] are both lethal drugs, but when they are combined, they become even more lethal. It’s like playing Russian roulette,” Clare explains. “One day your body can handle all the drugs, and next day it can’t. Chris could have died of a heroin overdose, a cocaine overdose or a combination of both. Cocaine can cause a heart attack and heroin can cause someone to stop breathing because it slows down the functions of the body. His death could be either heart or lung related or even both.”
