ummm.....ok, never used it and i cant see myself using it in the near or distant future. Ive never smoked etc......

Very much a case of "i dont think i would be desperate enough to go there" !

Having said that - i am not judging anyone who would choose this as a form of induction. I think it wouldnt be wise if you were a first time user, but if you have used before and know how you would react then.....

An interesting topic though......
