Europe is still big on regular ole' hash. BHO, wax, shatter, etc is a highly more concentrated type of extract. I'm sure there's people blowing trim in Europe but my cousin in the UK tells me he's never seen anything besides just hash. Maybe some other Euro head can tell me about the scene there. Might be different in certain countries. The concentrate scene is still relatively new, started to catch on real big in California only about 5 years ago and most of the US without medical/legal still doesn't have much access to concentrates outside of hash.
