I'm going to help you out. With teenagers if they are mature and old enough you can tell them, otherwise just smoke when they are out, or search on what a doob tube is and how to smoke hiding from your parents. Put the weed in the pipe, just put a small piece of weed, and grind up a little and put that on top. Light, inhale, exhale, repeat as needed. If your pipe has a carb you should use it, by putting your finger over the hole while you inhale, until the last second to clear the chamber. You can google how to roll a joint. I treat my condition daily for one of them(insomnia), and as needed for other things. Don't really tell anyone about it, read these boards up some, and you should be fine with cannabis knowledge.
