The cause of death was a combination of multiple drugs including cocaine, angel dust (PCP), Quaaludes, and Seconal, which led to what the coroner described as one of the most massive overdoses he had ever seen

. Jones had struggled with drug use, which intensified after she gained access to the nearly $200,000 she earned from her acting career, most of which she spent quickly. On the night of her death, she was at a party in Oceanside, California, with her boyfriend and friends, where she consumed the fatal combination of drugs. She was found unresponsive and pronounced dead at the scene

. In summary, Anissa Jones died from combined drug intoxication involving several substances at a young age, marking a tragic end to the life of a child star who faced significant personal struggles after early fame
