The last thing a child wants is for their parents to find their stash of weed. Before they get mad, tell them why you have the weed and, if it is for a good use, your parents may understand and not get as mad. But, if you are using the weed just to get high you will have a lot more to explain. Those desperate may try to claim the weed is not theirs and that it belongs to a friend in hopes that their parents will believe them.
