Anne Heche's blood test "revealed the presence of drugs," Fox News Digital can confirm. A Los Angeles Police Department Public Information Officer told Fox News Digital on Thursday: "Based on the blood draw, it revealed the presence of drugs, however additional testing is required to rule out any substances that were administered at the hospital as part of her medical treatment." Per the LAPD, "additional testing has been sent out "to rule out anything that was administered at the hospital." "Any secondary drugs [takes] up to 30 days for [a] secondary test to come back," authorities tell Fox News Digital. According to TMZ, Heche was under the influence of cocaine and possibly fentanyl when she crashed her vehicle into a home in Mar Vista on Friday and caused a fire, which destroyed a home and sent the actress to the hospital where she's currently in a coma.
