I just recently got my hookah along with a whole bunch of tobacco. Some tasted like crap so my girlfriend tried and experiment, we mixed the horrible tobaccos together and put diet coke in the base. Now, if you want to get very dizzy, this is for you. Not only do you get a huge buzz from crappy tobacco, but the co2 released from the soda floors you so bad, I took about 5 drags and I nearly passed out.
I put some pear slices in the bottom with some water and using pear shisha. I don't think it really enhanced the flavor to tell you the truth
