I roll the powder bubble hash right into the herb, mix it up before rolling.
I roll pressed hash into long thin snakes and put in the middle of a good size joint......not a fatty, but cant be a pinner either.

My favorite joint is Sweetskunk with about 25%powder hash, then roll the joint on 6week flowering Purple Kush buds in the grow room, get her good and greasy, then light it up and share with your friends!
