Have to admit in my day (admittedly a very long time ago) we weren't smoking tobacco in our hookahs but sounds like times have changed. I'd still keep an eye out though.
I remember a girl coming into the clinic I was working and had strep throat, and some infection around her mouth. When I inquired about her recent doings, she stated she had not done anything unusual.. oh except she had only went to a hookah bar.
I would use caution.. maybe use your own wipes.
My son told me that they can also be used for MJ but if any are found with traces the penalty is extreem.
That's all I know about them.
