Cannabis resin looks like a dung ball or comressed brown stuff. The "Solid" can be heated and the smoke given off is directly breathed in this is now as "Hot Rocking" (
Rock another term for Solid). If it is lightly heated it can be crumbled and mixed with tobacco to make a
joint. For the best effect use a cheese grater to
grind the "Solid" into a power and add to a joint with tobacco.
