Ex-NBA player Rasual Butler had multiple substances in his system at the time of his fatal crash back in January ... including alcohol, marijuana and painkillers ... according to the autopsy obtained by TMZ Sports.
As we previously reported, Butler was behind the wheel of a Range Rover -- with a female passenger, Leah LaBelle -- when he lost control around 2:30 AM and crashed into parking meters and a concrete wall. Both died immediately from injuries suffered in the crash.
Toxicology results show Butler's blood alcohol level was tested from blood collected from his heart and leg. The heart sample showed a BAC of .118, above the legal limit.The leg sample showed a .062, which is under the legal limit. One law enforcement source told us the results are consistent with a person who was legally drunk. Tests also show Butler tested positive for cannabinoids (marijuana), methamphetamine and oxycodone.
