The size of your joint, hand pipe, bowl and amount of times per day you use will determine how long your cannabis will last. Many long time users tend to roll larger joints or use larger pipes and smoke more, so for those folks the scale may be skewed. Many times when you are with others alot more tends to get stuffed in a rolling paper.
