Yeah - thanks. Exactly that - weight and potency. Imagine adding a bit of niqotine and stuff like that. Last year we could buy very very soft black hash, that if it was pure would have been awsome. It was just too cheap. I bought a couple of grams (didn't want to miss the opportunity to buy a good ball of hash for 25% of normal price) It just gave me headache. Definitely added some kind of oily stuff to that hash - ew.i feel u guys, brimi looks like u got a nice selection, i have also wondered why people spray and contaminate good weed for, what is the purpose, added weight or to fuck u up?
