I'm pretty sure you meant 'toxicology', and I would love to know where you read that. Those kind of reports take WEEKs to get back. Also, the report she passed out in a bath tub is nothing more than rumor at this point. So, while truth may not be trolling, I would contest your definition of truth.
Yes, that is what I meant. Simple typed the wrong word and didn't proof-read. History of substance abuse. Seen drinking and known to be taking pills the night before. Showed up to Grammy practice smelling of liquor and looking a bit out of it. Half a dozen prescription bottles in her room. Various outlets reporting different things. Some reporting very, very little and some reporting that a bottle of pills were scattered around her when she was found in the bathtub. A few of the pills found were Lorazepam, Valium, Xanax, and sleeping medication. Drink heavily and mix pills = not a good combination.
PS. Several reputable sources have stated that witnesses (friends) saw her drinking heavily and mixing Xanax. But once again, her substance abuse isn't my issue. Caring more because it is someone famous is. Many wouldn't care at all if it was someone down the street.
