Can I ask a question?  Where does one get this OI

Can I ask a question?  Where does one get this OIL to put in it.  I don't live in a MMJ state and I am not familiar with this oil and don't know where to get it? It is hard enough to get good old bud, but oil?  Also, what is the big deal with this cigarette?  What is so special about it?  There are many vaporizers available that use just good old plain old bud, why would I want to buy something that I can't get the product to put in it?
