During recording, bassist Sixx was involved in a serious car crash after drunkenly stealing a friend's Porsche in Los Angeles. At around the same time, actress and friend Demi Moore told Sixx he needed Alcoholics Anonymous, though Sixx dismissed her concerns. Sixx badly injured his shoulder in the crash and was prescribed Percocet, a combination of acetaminophen and the powerful opioid oxycodone which was commonly prescribed to treat severe short-term pain. Sixx's use of Percocet transitioned directly to a crippling addiction to heroin which would cost him $3,500 a day and almost claim his life later in the decade.
