It is dirty resin. The worst type of resin u can buy i think. it is cut by so many dealers along the line so by the time it gets to u it is so unpure. i have no idea what it is made from and i dont know what other chemicals other than thc are in it, i hear rumours of boot polish every now and then!!! u can tell how unpure it is by how brittle it is, good hash shud be bendy after warming it in your hand but u need a lighter to make this evn crumble off. my advise DO NOT BUY IT- but it ia dirt cheap-£40 on the ounce in LOndon apparently. it gets u high but its horrid.

happy toking
