And on the subject of 'bath salts' - another problem with this term is that it's a catch-all for quite a number of drugs: early on it was often various phenethylamines, a class of psychedelics which at least has been studied and documented by Alexander Shulgin in his book PiHKAL, but more recently it has come to mean one or more substituted cathinones (including MDPV, mephedrone, and methcathinone, all of which have proven to have horribly unpredictable and sometimes violent results) for which research on human consumption does not exist, save for the experiences of the crazy people out there who are basically experimenting on themselves. You can search youtube and find any number of videos showing users displaying absolutely frightening, uncontrollable dyskinesia. Users often run high body temperatures are are thus often found in states of undress, having removed articles of clothing in an attempt to cool off.
Last year I happened to encounter a neighbor who had taken bath salts. I first became aware of a young man rolling in a patch of dirt, making the most inhuman cries and yells. He sounded so anguished that I thought he must have just lost a relative or a beloved pet. I was walking to the mailbox at the time and he was across the street, so I didn't try to interact with him. On my return I saw him in the middle of the street, shirtless, trying to tap on the windows of cars passing by. Suddenly he took off running at top speed down my block. After he went about 2-3 houses down, he abruptly stopped, looked around wildly, then jumped over a fence and begin looking in some trash cans. I was walking towards him because my house was in that direction. When he saw me, he ran out of the yard and farther down the street, and then basically repeated the process of jumping into the neighbor's yards and looking in bushes or trash cans, periodically shouting unintelligibly. I've seen a lot of psychedelic drug use but I've never seen anything like this before. His repetitive, start/stop behavior continued the entire way down my block. Guess where he stopped? At my driveway. I had failed to take my cell phone with me so I couldn't call the cops. I actually hid behind a parked van until he once again took off running and yelling in the direction from which he'd came. At that point I went in my house, got my phone, and called it in. Uniformed officers responded, called for paramedics, and he was transported to the hospital. He later admitted buying bath salts at a local head shop.
I think we can say with a fair degree of likelihood that GG was not taking bath salts on the day he attacked Jenise; otherwise, people would have taken note of his behavior.
