It's my opinion that the initial tox report only covered drugs that are implicated in DUI: alcohol, cocaine, meth, opiates, barbs, and pot. It is only my opinion that they didn't test for any other drugs because that would involve multiple tests, some of which may be impossible because of the way the drug breaks down in the body, or because it doesn't show up in blood to be tested for.
Again, if ANYONE can show me a criminal investigation that showed a tox report that included every drug a person could have been taking, including OTC drugs, I'll retract what I said. But I still aver that just because the tox report that was made didn't show anything but alcohol and marijuana, it doesn't mean that other drugs weren't present in her system. It only means that they weren't tested for--and how would they know what to test for unless Daniel Schuler said, "She took OTC antacids, she had allergies so she was taking OTC antihistamines, she had pain so she was taking Tylenol."
But they wouldn't say, "do a test for every possible drug she might have taken"--that's virtually impossible to do. And if Schuler didn't know what drugs she might have been taking (who knows? I got a friend to give me a Vicodin once), he couldn't point law enforcement in that direction.
If she'd popped a double dose of Tylenol upon waking and then started to drink, the combination could have caused confusion. She might have figured a joint would smooth her out. Her liver may have been very busy trying to metabolize alcohol on top of acetominophen, and failed. And I still think there's a possibility that she was secretly taking carelessly prescribed ADs and had no idea that they could react on her.
