I just learned last night about packages of incense that are sold behind the counter at a hookah "lounge" in town. The word, from their competitor down the street--who really is a hookah lounge (the other mainly sells cigars, tobacco, etc and hookah is just something they've added) is that this place is using some sort of additive that has caused certain Navy people who were in town to have positive drug screens and so word is not to go there if you need to be tested. It is not known what is popping up on those screenings. So last night I stopped in and bought some shisha and went to the counter to chat with the 2 guys running the place about it. He denied that they use any additive. But he grabbed a packet of Black Mamba from behind the counter to show me...not sure why...and told me this is an incense. I looked at the ingredients. He denied that they put this in there, that it is burned just like incense--for aroma. They also had packets of Dead Man Walking, Cloud 10 Storm, and some others. Rather than writing down all the names--as I wanted to research it at home--I just used my cell phone camera and took a photo of each for reference. At that time he became very defensive and very rude. So today I started trying to research these products but for some reason can't find anything out. Does anyone know about this stuff and is it used as an additive in hookahs???? I'm interested from a clinical standpoint as I am a medical professional. Also though I do smoke shisha and don't want to have to do a uds for work and patron this place where they might be doctoring up their bowls. Any info would be greatly appreaciated!! Thanks.
