Blonde hash is from Lebanon and is one of the more prized and rare forms of Hash... I would assume that if you are not in the netherlands there is a decent chance being ripped off.. Hash is much easier to rip people off on..
In the UK alot of hash is shitty, soapbar as it's called, because it is simply quality hash that has been ground down, adulterants added(saw dust, roofing tar), and then repressed.
In the US hash is usually the real deal or "High Times" fake shit, due to the fact it is so rare to begin with here.. The hash i bought awhile back was good stuff and it was dark brown, milk chocolate color, and very hard.. 1/4 of a gram would have you nice and high..
In the future, either ask to try it first, or stick to the green. 8)
