can you roll a blunt with 0.7 g(almost a gram.)?!
if by blunt you mean mix it with tobacco, then what a stupid question.
if you mean roll it up with a cigar paper or one of those flavored tube papers, then probably not enough to fill one of those wrappers
if you mean roll with a standard rolling paper then yes, you can roll as small as necessary to get a good firm joint.
As far as the smart aass "answer my question then leave" , why don't you just take your .7 and try to roll it, numbnuts.
Ya, old school it's called a pinner.
**** yeah i did it with an eighth work that **** out
