The one we come across lately is named Black Mamba, we had others by some other wierd names I don't remember... pretty sure its all the same type of synthetic stuff.
The most common complaints by all the pts of mine were Feeling wierd ( in not a good way, like he was going to pass out or die ), vision problems ( described as blindness ), dizzyness and the feeling of a rapid heart rate.
One girl had abd pain, nausea and headaches.
I have heard about worse reactions, but have not come across them yet.
You can smell the stuff in the house, which has been clue #1. Symptoms from the pt direct me to ask about incense, most have been very honest.
Most have been younger folks ( under 30 ). I had one 65 year old that said he was trying to cover up the smell in the house with it, I am pretty sure he was lying his A^% off that he was not intentionally using it... social history made me lean that way.
Treatments have been the same. IV... monitor and transport.
Guess being high on life just is not enough for these folks.
