yeah there is a big call for it round here, tac it is sometimes called which i understand is melted down upon entry to the UK and has engine oil etc added, also plastic. This explains why sometimes you find small bits of plastic inside. If the seller tells me his solid is pollen it is a similar but softer substance which sprinkles out more and has a much better stone to it, this is better than tac but about double the price, Ive had pollen what gets you more stoned than green and the resins in the dam are beyond belief
