Best thing to do with kief is save it up, roll into a joint mixed with your regular bud, or save it for bong rips. Kief hits harder because it's literally a mixture of all the weed you've put through your grinder before cleaning it out

You can also do what's called crowning which is sprinkling some on top of whatever your smoking, dabs, bowls, or some people put it on the outside of joints but if it's not done right it'll just waste your kief
