I personally recomend that you roll a joint. Now you CAN do this. Roll a paper around a pen and stick it down so you just have a tube. Put a little rolled up piece of cardboard in the end for filter. then just fill it up with your broken up bud. I guess if your not sure of your tolerance...take a few hits then extinguish the rest of the joint. Full effects take 10-15 minutes to manifest and at that point you can determine how much or how little you need.
