And dabs are not hash. Well it's kind of a high grade hash. We don't get it in the Uk, if we do it's rare. It basically made with butane and is concentrated THC I assume, I know it's mostly for "medicinal" purposes but most people now use it recreationally.
Some videos I've seen of people taking large dab hits are hilarious. They look like rookies on their first bong hit. :|
