hash ciggies are awesome, personally i find it best to heat the BHO up first and use a piece of paper clip to spread it as thin as possible so that it burns evenly, sucks when the ciggie is dropping fat embers and burns holes in yer jeans
It works fine but, you won't get nearly as high as dropping bombs on a nail or skillet. Not to mention pretty wasteful. If you have lot's of errl to spare go ahead. I use to do this all the time when I smoke tobacco. Mini G pen is more portable and efficient for me.
